AngelList's mission is to accelerate innovation by providing startups and investors with the tools they need to succeed. We have the world’s largest early-stage venture portfolio with $17B+ assets under management and $124B+ on our platform, delivering capital to over 12,000 startups.

We’re Zed Industries, a small and passionate team with a vision for building the world’s best text editor—for you, and for your team.

Zed isn’t our first editor. It’s the culmination of more than a decade of experience building tools for developers.

In the same way image generators have shown the remarkable ability to produce a diverse set of realistic pictures conditioned on a text prompt (and other inputs), we are developing a generative model that produces 3D geological models conditioned on geophysical surveys, bore hole measurements, and other forms of physical observation. The outputs of the generative capture what we know and don’t know about the state of the subsurface, allowing explorers to make maximally informed decisions about how and where to explore for critical resources.

We believe SMBs are the backbone of American society and small business ownership is the best path to wealth creation and economic mobility for many Americans. We're trying to dramatically lower the activation energy in just one of the major hurdles for aspiring small business owners: accounting and bookkeeping.

Our approach is working! We embed directly within an SMB's primary business platform, manage all the data syncing & reconciliation for them, and have real humans (with real AI tooling) handling their books. We do this at ~half the cost of existing bookkeeping services and it's still profitable for us because we're saving so much time with our data access + AI.

Adoption is taking off faster even faster than we hoped and we need to grow the team! We're a team of 5 who like working with a high ownership and high throughput collaboration. We have serious technical challenges across scaling systems, data modeling, and building AI-driven automations of tedious tasks.

We want teammates who love learning and want to be involved in company building from the ground up - even if you aren't familiar with accounting or our tech stack. We have tier-1 investors, thousands of SMBs on the platform, and revenue has 10x'd in the last 6 months - it's a very good time to join us.

Join us in building Ameba, an AI platform that turns supply chain noise into knowledge.

If you've never considered working in supply chains before, everything around you, including the device you're reading this on, has a story of how it got there. From raw materials to the final product in your hands, that story is its supply chain.

If you're the kind of engineer who thrives on solving novel challenges, such as building modern data pipelines to construct a supply chain from unstructured communication streams, Ameba offers you the opportunity to build from first principles in a greenfield space.

We're a seed startup made up of experienced entrepreneurs (who have previously raised $160m+, built supply chains for 30+ brands) and builders (formerly at Meta, Microsoft, Snap, Apple & Palantir). We have big ambitions and are backed by the best investors in Europe, having raised over $9m since our launch just over a year ago — and we're just getting started.

If you're interested, please email me directly via craig (at) ameba (dot) ai with [HN] in the subject. Note we are currently unable to sponsor visas.

And learn more about Lumafield below:

Lumafield was founded in 2019 to upgrade manufacturing.

We are engineers with deep experience across the product development cycle, from initial ideas to shipping hardware, across industries and specializations, who became frustrated by the cost and complexity of modern manufacturing. So we decided to upgrade it.

Engineers make million-dollar decisions every day, and they need tools that give them the greatest possible insight into their products. By offering unprecedented visibility into products, as well as AI-driven tools that highlight problems and generate quantitative data, Lumafield promises to revolutionize the way complex products are created, manufactured, and used across industries. We started with industrial CT scanning, which for us was the most valuable but underutilized tool in the manufacturing toolbox, enabling us to rapidly inspect essential components non-destructively.

We rebuilt the whole system, from X-ray capture, to computer vision analysis, to web-based collaboration, to the entire business model, making the most advanced manufacturing tech more accessible to every industry. Our company, like our platform, is designed for upgrades. We’re building for greater intelligence, autonomy, and speed. For deeper vision, operational excellence, and powerful insights. And then we'll upgrade it all again.

Lumafield is headquartered in Cambridge, MA, and has an office in San Francisco, CA.

Tech used: Python, C#, JavaScript, SQL, Swift

We're hiring for multiple software engineers to help tackle one of the most important sectors for the global economy: maritime shipping.

We’re building the [“strong form”](https://www.youtube.com/watch?v=2ZpJXHiPwtQ&t=498s) AI agent app for business communications. We’re focusing on email initially, as it’s (1) ubiquitous (2) open and (3) has a diverse set of valuable business data. In the future we plan to expand beyond email to include all essential business communications tools, including Slack, Teams, CRMs, document platforms, project management tools, and so on.

Most people’s experience with AI today involves copy & pasting content back and forth from ChatGPT. Not only is this a terrible UX — it severely limits the transformative potential of AI.

Our goal is to unlock 10x (or greater) productivity gains for the average business user by bringing cutting edge AI together with their business communications in a single app designed for effective human-AI collaboration. With Shortwave, users can give the AI access to all of their data and then allow it to take action while still maintaining total control over its output.

You’ll be joining our team as a senior developer eager to find cost-effective, high-quality, pragmatic solutions to our clients' complex problems. You would be tasked to lead technical direction for connected hardware products — consumer devices, bespoke operating systems like the Light Phone OS, and the digital ecosystems of phone apps and web interfaces that talk to them. You might identify as a Technical Lead, a Technical Architect, or a Technical Program Manager, and — as you might expect with “technical” in the title — you would be the person on the project team most responsible for delivering the most appropriate and cost-effective technical solution for the client’s needs.

We're looking for someone to lead our small-but-growing engineering team at our Hudson Yards office. There are about 10 full-timers in the office, with more members being added to the product and engineering teams this year. I'm leading product and the search for this role.

This is a unique opportunity – we're building a comprehensive dataset of mental health services and outcomes while prioritizing user privacy. As a nonprofit, we have no incentive to monetize user data. Instead, we're focused on two things: 1) helping people access care across the full treatment spectrum through our screening process (as developed with our clinical advisory committee), and 2) understanding outcomes by collecting anonymized outcome data to understand what actually works in mental healthcare - something that surprisingly doesn't exist yet at scale.

Our goal is to simultaneously solve the discovery problem for people seeking care while building the dataset needed to improve mental healthcare quality and accessibility.

Sideline is a rapidly growing SaaS product for law firms that enables a track changes feature for draft emails within Outlook.

Around 30 law firms are currently using the product across three continents. Sales have been inbound. The company is bootstrapped. I am the sole founder looking for somebody to take the lead on the technology side so I can focus on growing the business.

Sideline is a web application. You will have full ownership of the codebase and SaaS infrastructure. You will interact directly with customers, being included in product feedback calls and some sales meetings.

Technologies used: JavaScript (some jQuery - not for long), TypeScript, Node.js, Azure, MS Graph APIs, Office JavaScript APIs. Note this is not a .NET/VSTO/COM Add-in.

Background on me: I was a corporate lawyer for 10+ years, as well as doing a bit of legal tech consulting, before founding Sideline. I’m active on LinkedIn.

If interested to learn more, please email: daniel at trysideline dot co.

Flexible hours, minimal meetings, fully remote

Tech: TypeScript, Python, Nix/NixOS

We have a suite of end-to-end tests that each spin up a virtual network from scratch to test our application. This test suite gates our automated release process and has been critical in allowing us to ship updates to users quickly and confidently. We'd like to expand it further and are looking for someone who cares about automation and correctness and can help us greatly expand what we test.

Part of the tests are written in Python (since that's what the NixOS test infrastructure provides) and part of the tests are written in TypeScript (the parts that drive a headless web browser). We developed our own convenience library on top of Puppeteer that make tests easier to write and more reliable than Puppeteer, Playwright, or Taiko (all of which we used previously). The tests can run locally (on Linux/MacOS development machines) and they run automatically on push to our build servers. The build servers are modern bare metal servers with Ampere and AMD CPUs with enough RAM to run dozens of test networks in parallel.

We have a simple review/interview/hiring process and low employee turnover.

DeviantArt was founded in 2000 and has been a part of Wix since 2017. It is the largest online social network for artists and art enthusiasts. For emerging and established artists, DeviantArt is the foremost platform to exhibit, promote, and share works with an enthusiastic, art-centric community. We have over 86 million registered users worldwide, and our users -- lovingly referred to as “deviants” -- upload tens of thousands of original pieces of art every day, from more traditional art like painting and sculpture, to digital art, pixel art, films, anime, and AI art.

We're looking to add another to our very small remote distributed DevOps team. The DevOps team performs all tasks normally inclusive of SRE/DevOps/Infrastructure Engineers, with a bit of database administration mixed in. We are responsible for the day-to-day management of large-scale, mission-critical production systems that run on a public cloud. We automate, manage, and maintain the global infrastructure that makes DeviantArt tick. We respond to and mitigate all system issues. We develop and support the developer environment, and build and maintain CI/CD pipelines. The job lists the location as Kyiv, and although going into an office could be an option, preference would be for 100% remote.

This job requires an on call rotation, and needs a generalist knowledge of a large complicated site infrastructure, excellent linux command line skills, some database skills, and an enjoyment of troubleshooting and solving complex issues, sometimes during system events and outages.

We take our work seriously, but don't take ourselves too seriously :) Come work with us, enjoy remote flexibility, have fun, and build neat things.

Camber is working to improve the messy financial infrastructure for US Healthcare. We've built an automated end-to-end insurance billing system for recurring care, starting with Autism clinics. It’s a product that clinicians need and love.

We automate and abstract the tedious, manual, repetitive work that goes into the administrative duties of running a clinic, so that clinicians can do what they do best — providing care.

It starts with ingesting clinic data, and then create, validates, and submits claims to insurance providers across the country. If claims need corrections or appeals, most of the time we can handle those automatically or our CX and Operations team use our in-house internal tools. We also handle patient invoicing for co-pays, co-insurance, and deductibles (we never send anything to collections). We track money movement on a unified ledger and reconcile transactions with clinics' bank accounts.

There is so much more to build. If you're interested in scaling data pipelines, programmable rules engines, AI, data science, delightful products for small clinics, processing billions of dollars in money movement or solving the unsexy problems that make this country's healthcare broken, come join us!

We are a team of ~40 with strong product market fit. You’ll be working with an engineering leadership team from AWS and Stripe to get clinicians back to work delivering care for kids.

Building stuff in crypto today is really hard. Imagine if you wanted to put up a personal website and all you had to do was start by breaking ground to build a data center. Your personal page probably would not be that good, would it? Small teams can only focus on so many things; we want them to use center so they can focus on the details that truly matter and make products beautiful.

We want to eliminate all of these annoying, cumbersome, expensive problems that devs face so that they can build incredible user experiences that help people flourish and rise to the level of their ambition, without having to think about if their nodes are online or if their indexer is missing any data.

Gel is an open-source data platform built on top of Postgres. It’s designed to give developers a better end-to-end user experience than traditional SQL databases. We provide a more expressive schema modeling & query language (EdgeQL), and "batteries included" features such as built-in schema migrations and a graphical schema browser, data explorer, and access control/auth.

We offer a hosted cloud service for Gel, with the goal of doing developer-friendly cloud hosting "the right way" - we want users to use our hosted service because it's great, not because they're locked-in by restrictive licensing or cloud-only features.

We are looking for experienced SREs / infrastructure / devops engineers to help scale out our cloud. Unlike many infrastructure roles, this is not supporting a separate product team - for us, our infrastructure is our product. We are looking for people who care about not just building reliable infrastructure but also exposing that infrastructure to end-users as a seamless product.

Our tech stack is Hashicorp tools (Terraform, Consul, Nomad, Vault); Postgres; Golang with some Python & Rust; and AWS (with eventual expansion to other cloud platforms). It's a requirement that you have strong experience with Golang.

We are a remote-first company, headquartered in San Francisco, with most of the team working in US/Canada timezones and a few people in Europe. Unfortunately we are unable to provide any visa/immigration sponsorship at this time.

We've scaled to >$3MM annual revenue and 400k MAU with our small team. We're hiring for multiple roles and are primarily interested in people with early-stage company experience, who are comfortable in high-agency, fast-paced teams.

Reasons you might want to join Elicit:

1. We have been thinking about how to apply AI for high-stakes knowledge work since even before GPT-1. Elicit was spun-out from Ought (https://ought.org/) which was more of a research lab.

2. If you're concerned about the potential downsides and risks of super-powerful AI: so are we! Happy to explain more of this story on a call, or you can also check e.g. https://ought.org/updates/2022-04-06-process for a primer.

3. We like spending time with each other, and have get-togethers every 6 weeks, but we're flexible on location.

Reasons you might not want to join Elicit:

1. We've found a level of product market fit (as evidenced by metrics) but we've not proven everything out yet. If you want predictability, Elicit is not for you.

2. We aim to hire people who thrive in low-bureaucracy environments, and let them loose. If you need structure, lots of support, close mentorship, or tightly-defined work assignments, Elicit is not for you.

3. We just raised a Series A, so if you want existential dread (and concomitant founding-team-upside), Elicit is not for you.

Perhaps off field, but I'm recruiting a PhD student in Aarhus University in Denmark (in person or hybrid). It's salaried with pension contributions and help relocating, and the agreed pay is equivalent to a graduate job in Denmark.

Title: Multimodal Medical Imaging – AI and Quantum Physics for Diagnostics

Call for applications for a fully financed PhD fellowship

Project description:

Life creates order in a universe where disorder always increases. The set of chemical reactions enabling this —metabolism— changes as we eat, sleep, exercise, or become unwell. This PhD studentship is for a transformative research project integrating physics, mathematics, artificial intelligence (AI), and cutting-edge medical imaging to unravel and quantify these metabolic processes inside people.

Hyperpolarized MRI (HP-MRI) uses quantum mechanics to boost the sensitivity of MRI by orders of magnitude, allowing real-time imaging of metabolites like pyruvate as they are processed in vivo. Unlike conventional imaging techniques such as PET, HP-MRI avoids ionizing radiation, measures multiple metabolites simultaneously, and directly maps reactions like glycolysis and oxidative phosphorylation. It is uniquely powerful for diagnosing and monitoring diseases like cancer, multiple sclerosis, and Alzheimer’s, with its clinical potential currently being explored in multinational trials.

The EU-funded project "Quantum+AI for Diagnostics" (Q-AID) tackles one of the most fascinating challenges in medical imaging: mapping the relationship between underlying biological "truths" (e.g., tumor metabolism) and the signals captured by imaging systems, which are subject to noise, artefacts, and are imperfect. These mappings are deeply complex, involving layers of transformation —signal generation, reconstruction, and visualization— before even addressing the biological dynamics of living organisms. Metabolic systems are vast, interwoven reaction networks, where only a subset of processes can be measured directly. Using "physics-informed" neural networks, we aim to combine analytical knowledge with AI tools to infer unseen processes.

In this studentship, you will:

• Develop super-resolution models to overcome the spatial resolution limitations of HP-MRI, leveraging data from conventional imaging

• Model imaging processes mathematically, bridging biological truths and observable signals.

• Design AI approaches for semantic segmentation and metabolic classification, integrating multimodal imaging datasets.

• Quantitatively unify HP-MRI with other modalities like PET and CT.

• Work closely with clinicians to build life-saving tools that will impact patient care

A trillion dollars in GPU compute power will be deployed this decade. We are building the framework and tools that will enable them to operate at full capacity. We are looking to expand on our engineering side and are interested in hiring people who can demonstrate proficiency in writing C/C++ code, CUDA, Python and a good understanding of a GPU internal operation.

No bullshit interview process. I would probably talk to you for around half an hour about what you’ve done related to this. I may ask to see some code you’ve produced in the past. No take-home assignments. If there’s promise, you may be asked to work one or two weeks with us, paid.

If you are a student or just graduated, we have a couple internship spots. We don’t mind training people if they show strong interest and adequate fundamental skills.

Manifesto: Manufacturing is important. It’s the fundamental industry on which everything else is built. We take it for granted. In 1989, 35% of the entire software industry was manufacturing systems. Back then, services, hand holding, customization, and consulting were necessary to get the systems to where they are today. What was the first massive burst in productivity from technology has stagnated into incremental diminishing returns and exponentially increasing complexity. We can only continue to add complexity for so much longer until the whole system collapses. "Any intelligent fool can make things bigger and more complex. It takes a touch of genius and a lot of courage to move in the opposite direction." Manufacturing is important.

Roboflow is the fastest way to use computer vision in production. We help developers give their software the sense of sight. Our end-to-end platform [1] provides tooling for image collection, annotation, dataset exploration and curation, training, and deployment.

Over 1 million engineers (including engineers from 2/3 Fortune 100 companies) build with Roboflow. We now host the largest collection of open source computer vision datasets and pre-trained models [2]. We are pushing forward the CV ecosystem with open source projects like Autodistill [3] and Supervision [4]. And we've built one of the most comprehensive resources for software engineers to learn to use computer vision with our popular blog [5] and YouTube channel [6].

We have several openings available but are primarily looking for strong technical generalists who want to help us democratize computer vision and like to wear many hats and have an outsized impact. Our engineering culture is built on a foundation of autonomy & we don't consider an engineer fully ramped until they can "choose their own loss function". At Roboflow, engineers aren't just responsible for building things but also for helping us figure out what we should build next. We're builders & problem solvers; not just coders. (For this reason we also especially love hiring past and future founders.)

We're currently hiring for full-stack engineers to help build our product, field engineers that work directly with our customers to solve their business needs with computer vision, and several technical roles on the sales team.

We just raised our Series B round, led by GV. With this round, we will continue building the open source tools, platform, and community so developers and enterprises can deploy computer vision applications to production. [7]

Felt is building a cloud-based geographic information systems (GIS) solution and have hundreds of customers already using it to run their operations, processing terabytes of data. Our team hails from Uber, Google, Meta, CARTO, Mapbox, The New York Times and a few others. If you have used online maps in the past few years, you have used their work. My co-founder and CEO, Sam, is a former YC founder who sold his previous company [1] and I'm an early Uber engineer.

We are on the lookout for a Senior Infrastructure Engineer who will help build our GIS architecture in the cloud. Felt built the world's most advanced cloud-native GIS systems. We are able to processes almost all types vector, raster, and tabular data you can throw at it. You can throw a basic CSV or a multi-band raster file with NDVI encoding. Felt can also natively connect to STAC repositories, process data from your Snowflake installations, or download things from your Redshift.

We are looking for a senior or a staff level engineer who will help us take this architecture to next level. We are always adding support more types of files and connectors. We also have some ongoing projects to make this infrastructure more modular and work in VPCs.

Ideal candidates will have experience working with infrastructure as code tools such as Cloudformation, CDK, Terraform or similar. We handle many different types of data on a daily basis and it's key that we iterate really fast; our IaC tools enable us to do that with confidence.

Also, for the first time, we are hiring a product manager that is going to be focused on our growth funnels within our service. This person will own the onboarding journey and help those first-time customers become loyal users. . Ideal candidates will have 4+ years of experience focus on growth and onboarding within B2B SaaS and/or PLG companies. They will have a proven track record, own metrics such as time to value, be comfortable owning touchpoints, and designing and running experiments.

We are well-funded and just raised our $15M Series A. You can read more about it our funding here [5], and our announcement here [6]. Our terms are employee-friendly terms such as early exercise, a 10-year exercise window and even a matching 401(k).[7]

1. Impact: An opportunity to join an exciting deep tech startup that will challenge conventional thinking in Edge AI and TinyML.

2. Career progression: We are a small company so you will have an opportunity to shape the role depending on your strengths and ambitions (I promise to help you as much as I can here).

3. Friendly, knowledgeable teammates: Our team is experienced and enjoys sharing knowledge. We document our work, hold literature reviews and casual show and tells to help each other grow professionally.

4. Flexibility: We are a remote team and this provides you with genuine flexibility over where and how you work in collaboration with our team.

5. Unlimited Holiday: Beyond the UK minimum (20 days + 8 bank holidays), we offer the option to take additional paid holiday within reason and mutually convenient.

6. Equity: All permanent employees will receive meaningful share options in the company; we are currently in the process of implementing the option pool.

7. Pension: Literal Labs will contribute 5% of qualifying earnings to your pension.

In general, I'm determined to make Literal Labs a really positive experience for everyone working with us.

Chorus One operates validators on many proof-of-stake blockchains (the ones where security is based on a Byzantine fault-tolerant consensus algorithm rather than wasting energy). We are hiring for several roles, but the one I will highlight is what we call Platforms Engineer. Some companies call this Site Reliability Engineering or Devops.

The main thing we do is take upstream software, build it, run it on our infrastructure, and then monitor it and optimize that setup. Some things that make this interesting are:

    * Building automation that enables us to do this for many networks (70+ currently).
    * Doing this with high uptime, building automation for failover, etc.
    * Working with software that is on the one hand cutting-edge and doing interesting things (consensus algorithms, distributed systems, cryptography), but on the other hand that means it’s immature and often not easy to operate and monitor. Often we have to build custom tools, and dive into the source code of the project. We contribute patches upstream when it makes sense.
    * Some of these projects are exercising the limits of what a machine can do, we have to do some low-level investigation that requires understanding of what the Linux kernel and network hardware are doing to properly identify what’s going on.

A very recent example of what I personally find fascinating: last week Ethereum’s Holesky testnet experienced loss of liveness. This is a real-world, globally distributed system that implements Byzantine fault tolerance, with multiple independent implementations of the protocol. Several of these implementations had a bug in an update, which caused a split in the network. The protocol is designed to handle this situation in theory, but in practice it is triggering previously unexplored failure modes in the implementations, that are hard to test for in synthetic small-scale tests. I think there are very few places where you get to be involved in a planet-scale distributed system exhibiting “interesting” behavior, especially one that is not in control of a single entity. Of course, there is also the less fun part that the testnet is now broken, alerts are firing, and it’s hard and chaotic to coordinate a fix when the network is not controlled by a single entity. Fortunately it’s a testnet.
