AfterQuery captures how experts reason and turns real-world professional work into high-quality training data for frontier foundation models. Backed by Y Combinator.
About the role
Project and client management: Partner directly with frontier AI labs on their legal data and evaluation needs — scoping the problem, translating it into a deliverable program, and driving revenue. Manage expert contractor teams: Recruit and lead practicing attorneys and specialists across practice areas and jurisdictions — litigation, corporate and M&A, regulatory, IP, tax, employment — and hold a high bar on the quality of what they produce.
What they're looking for
- 3+ years practicing law at a leading firm, in-house at a sophisticated company, a government or regulatory body, or a legal AI startup
- JD (or equivalent qualification) and a track record of substantive legal work: you have drafted, negotiated, litigated, or advised, not just coordinated
- Deep command of legal reasoning and research methodology, and strong opinions about what separates rigorous analysis from surface-level answers
- High agency and the ability to execute in ambiguity, comfort defining the problem before solving it
- Analytical ability, can break down complex legal problems and work flows into component parts
- Genuine passion for AI and interest in entrepreneurship
