Founding Engineer (AI + Geometry / CAD)

ABOUT THE ROLE Join an early-stage team building AI-first software for architecture and construction, including a new BIM authoring tool designed for AI agents. You will help shape its technical foundations, with the opportunity to grow into a technical leadership role. WHAT YOU'LL DO - Build the geometry and data core of a new BIM authoring tool. - Develop AI agents that plan and edit real building models. - Create generative design capabilities that account for building codes and client constraints. - Work across the stack, moving quickly between unfamiliar technical areas as the product evolves. WHAT WE'RE LOOKING FOR - Production software experience; candidates with 1 to 2 years of experience should also have a long history of building substantial projects independently. - Hands-on experience with 3D geometry or CAD, such as geometry kernels, B-rep, meshes, CAD APIs, IFC, or Revit. - Daily practical experience building with LLMs and AI agents. - A generalist mindset, strong English communication, and experience in a startup or as a founder. - Experience with Python, PyTorch, TypeScript, or three.js is useful, as is knowledge of AEC, BIM, generative models, or visual data. - Experience leading engineers or making architecture decisions is a plus.
