What You'll Do

  • Build the geometry and data core of a new BIM authoring tool.
  • Develop agents that can plan and edit building models.

What We're Looking For

  • Experience shipping production software, with one to two years considered for candidates who have built substantial projects independently over several years.
  • Hands-on experience with 3D geometry or CAD, such as geometry kernels, B-rep or mesh systems, CAD APIs, IFC, or Revit.
  • Daily engineering use of LLMs and AI agents, with experience building production AI features.
  • A broad engineering skill set, comfort working across the stack, and the ability to become productive in unfamiliar areas.
  • Startup or founder experience and fluency in English.
  • Experience with Python, PyTorch, TypeScript, three.js, AEC or BIM workflows, generative or multimodal models, or technical leadership is useful.
