The role
An applied AI lab is building society-level simulations to help governments and policymakers tackle complex challenges. They're extending the frontier of LLMs and simulations in policy and social sciences, backed by leading investors. This is about bringing cutting-edge AI to bear on real-world societal problems, with transparency and auditability built in.
As a Founding Engineer, you'll bridge research and production. You'll benchmark models on new policy problems, build specialized research agents, and own the entire AI/ML layer end-to-end. This is a rare seat for someone who wants to do applied research that actually ships, not just publish papers. You'll be deeply involved in user research, ensuring your work solves real problems, not just theoretical ones.

Strong Python skills, modern ML tooling proficiency, and experience fine-tuning models. A track record of taking research ideas to working systems, with a clear view on practical application vs. hype. Comfort navigating ambiguity and the gap between model capability and user reliability. A genuine interest in public-sector problems and their real-world impact.
