Founding Engineer (AI + Geometry / CAD)
About the Role
This is a founding engineering role at an early-stage AEC software startup rethinking building design from the ground up for AI. You will help build the geometry and data core of a new BIM authoring tool, working directly alongside founders who have shipped widely-used CAD and real-time rendering products used by architects worldwide. There is no CTO yet, and the right person can grow into that seat.
What You'll Do
Design and build the geometry and data core of a next-generation BIM authoring tool, written from scratch for AI agents.
Develop AI agents that plan, generate, and edit real building models.
Build generative design systems that respect building codes and client-specific constraints.
Work across the full stack, picking up whatever area needs you most each week.
Contribute to architecture decisions and, over time, help shape the engineering team and culture.
What We're Looking For
Shipped production software; one to two years of experience is fine if you have been building serious projects independently for years, with more experience welcomed.
