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.

Compensation & Benefits

Stock options are available. Visa sponsorship is not available; candidates must already be authorized to work in the EU, UK, or Switzerland.

Location

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