One bit I’d love to see if you keep maintaining it: a layer for ambiguity / cross-functional weirdness. A lot of postings look like engineering, research, product, policy, and GTM all got blended into one JD. That can be a great role, but it is also where candidates waste a lot of time because the title does not match the actual day-to-day.

Even a simple “function confidence” or “role blend” field could help: e.g. 70% infra eng / 20% research support / 10% product ops.

Nice project — especially because the taxonomy problem is harder than it looks from the outside.
