Software Engineer

This is a founding-team software engineering role at an early-stage, AI-powered construction tech company based in Berlin. The company builds browser-based software that automates the generation of building design plans - covering technical building equipment and electrical schematics - dramatically reducing planning timelines from weeks to hours.

As one of the first Software Engineers on the team, you will have a direct impact on core architecture, infrastructure, and plugin/backend design decisions. You’ll help shape the tech stack, deliver prototypes, and drive the MVP to production across multiple ecosystems - all within a fast-moving, high-ownership environment.

What You’ll Do

• Contribute to the design and delivery of early-stage prototypes.
• Ensure the MVP is production-ready and built to scale.
• Deliver robust solutions across multiple software ecosystems.
• Write clean, maintainable, and well-structured code.
• Process and handle large volumes of CAD data efficiently.
• Participate in backend and plugin architecture decisions alongside the founding technical team.
• Contribute to infrastructure setup and tooling decisions.

Required:

• Proficiency in C# or Python for backend software development, underpinned by strong computer science fundamentals.

Strongly valued:

• 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 and backend/plugin architecture.
• Comfort working across multiple ecosystems and with large, complex datasets.
• An early-stage mindset - you’re energised by ambiguity, ownership, and building from scratch.

Background in AEC (Architecture, Engineering & Construction) software, or experience with tools such as Revit or similar CAD/BIM platforms, is a plus.

Compensation details have not been specified for this role. As an early-stage company, equity participation is likely part of the overall package. Specific details will be discussed during the interview process.
