Software Engineer

This is a rare opportunity to join a pre-seed AI-powered construction tech startup in Berlin as one of the founding engineers. You’ll work on a browser-based platform that uses AI to automate complex building design workflows - including technical building equipment (TGA) planning and electrical schematic generation - reducing planning timelines from weeks to hours.

Required:

• Proficiency in C# or Python for backend software development.

Strongly preferred:

• Experience with CAD data processing and implementing data structures and algorithms for scalable software.
• Proven ability to design, build, and ship production-ready MVPs.
• Hands-on experience contributing to infrastructure setup.
• Ability and enthusiasm to influence architecture and tooling decisions, including backend and plugin architecture.
• Comfort working across multiple ecosystems and with large, complex datasets.
• Strong computer science fundamentals.

Nice to have:

• Background in the AEC (Architecture, Engineering, Construction) software space.
• Experience with BIM tools or platforms such as Revit.

• Contribute to the design and delivery of prototypes for AI-powered building design features.
• Drive the MVP to production-readiness across multiple software ecosystems (including integrations with tools such as Revit).
• Process and handle large quantities of CAD data at scale.
• Help define backend and plugin architecture, as well as infrastructure setup.
• Write clean, maintainable, and well-structured code with strong CS fundamentals.
• Deliver solutions that span multiple platforms and ecosystems.
