Founding Engineer, AI and Geometry/CAD

About the Role

Join an early-stage team building AI-first software for architecture and construction. As a founding engineer, you will help create a new BIM authoring tool designed for AI agents, 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 can 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; one to two years may be suitable if paired with substantial personal projects.
• Hands-on experience with 3D geometry or CAD, such as geometry kernels, B-rep or mesh modeling, CAD APIs, or IFC.
• Regular, practical experience building with LLMs and AI agents.
• A generalist mindset, with the ability to work across the stack and get productive quickly in unfamiliar areas.
• Startup or founder experience, strong English fluency, and a willingness to work in an early-stage environment.
• Experience leading engineers or making architecture decisions is valuable, as is AEC or BIM domain knowledge.
• Useful technologies include Python, PyTorch, TypeScript, and three.js, as well as generative or multimodal models for 3D or visual data.
