Founding AI Engineer

We are looking for a Founding AI Engineer with 2-8 years of experience to join a mission-driven team automating architecture to solve the housing crisis. You'll work at the frontier of agentic AI for the built world, running high-autonomy experiments to improve multimodal agents that check blueprints for building code compliance — your work will directly impact how fast apartments get built in America.

**What will you be doing?** • Generate hypotheses and run time-boxed experiments to improve the accuracy of multimodal AI agents • Reflect on experiment results and update mental models to direct your own research roadmap • Work on supervised fine-tuning, model distillation, auto-research, retrieval tasks, and context engineering • Run computer vision evals and build internal tooling to accelerate experimentation • Talk to users and dogfood the product weekly

**Key Requirements** • Highly autonomous and self-directed — able to manage your own workload and generate experiments without being told what to do • Daily usage of AI coding tools (e.g., Claude Code, Cursor, or similar) • Blends SWE speed with ML rigor — not too researchy, not lacking experimentation skills • Must work in-person 5 days/week in San Francisco • Resonates with the mission of solving the housing crisis and wants to work at a seed-stage startup
