I built this website while exploring job opportunities at AI companies. Coming from an economics policy background (I ve done a good deal of research on the business/economics side gen AI, quantum and other emerging tech but I m not an AI engineer), I wanted to understand how different roles fit together inside these companies.So I started building a taxonomy to map job postings into departments and functions that is consistent across labs, making it easier for me to understand where each lab is hiring and for what. Out of curiosity, I expanded to see what s hot, etc. in technical areas too. It ended up being both job search and personal research project.Coming up with a standard taxonomy is challenging. I m still figuring out matching jobs to functions/departments, looking at other labs, and thinking of alt ways to organize this, eg., I see that companies associate job postings to specific teams, but I still don t have good descriptions of the scope of those teams to create crosswalks. I m also looking at other companies.So, sharing it here for others who may find it useful or want to comment. It d be great to have feedback from those who have insight into how these companies organize their departments/functions, and from technical job seekers too, if this is something that helps them better understand job opportunities. If people find it useful, it could become something I maintain over the longer term (particularly if I don t end up finding a job at one of these labs).
