Founding Engineer, AI and Geometry / CAD

About the Role

Join an early-stage AI and construction technology team building a new BIM authoring tool designed for AI agents. You will help shape its core architecture and may have 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 agents that plan and edit real building models.
• Create generative design capabilities that account for building codes and client constraints.

What We're Looking For

• Experience shipping production software, typically one or more years; substantial personal projects can complement shorter professional experience.
• Hands-on experience with 3D geometry or CAD, such as geometry kernels, B-rep or mesh modeling, CAD APIs, IFC, or Revit.
• Daily practical experience building with LLMs and AI agents.
• A generalist mindset, with the ability to work across the stack and become productive in unfamiliar areas.
• Startup or founder experience, and an interest in an early-stage environment.
• Fluent English; German is not required.
• Experience with Python, PyTorch, TypeScript, three.js, AEC or BIM workflows, or generative and multimodal models is useful.
