Founding Engineer (AI and Geometry/CAD)

About the Role

Join an early-stage AI and AEC software team building a new BIM authoring tool designed for AI agents. You will help shape its geometry and data foundations, and may grow into a technical leadership role as the team develops.

What You'll Do

• Build the geometry and data core of a new BIM authoring tool.
• Develop AI agents that plan and edit building models.
• Create generative design capabilities that account for building codes and client constraints.
• Work across the stack and take ownership of the areas that matter most as the product evolves.

What We're Looking For

• Production software experience. One to two years may be a fit if you have also spent years building substantial projects independently; more experience is welcome.
• Hands-on experience with 3D geometry or CAD, such as geometry kernels, B-rep or mesh workflows, CAD APIs, IFC, or Revit.
• Regular experience building with LLMs and AI agents, with production experience in AI or generative models.
• A generalist mindset, strong ability to get productive in unfamiliar areas, and startup or founder experience.
• Fluent English. German is not required.
• AEC or BIM experience, technical leadership, Python, PyTorch, TypeScript, three.js, or generative and multimodal models for 3D or visual data are useful.

Compensation & Benefits

• Stock options are available.
• Visa sponsorship is not available.
