About the role

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.

Location

Remote within Europe, including Switzerland and the United Kingdom. The primary location is Karlsruhe, Baden-Württemberg, Germany. Candidates should be based in Europe or willing to relocate there.
