Software Engineer

ABOUT THE ROLE 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. WHAT WE'RE LOOKING FOR 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. LOCATION - Based in Berlin, Germany. - Hybrid working arrangement — approximately 3 days per week in the office. - Visa sponsorship is not available for this role. COMPENSATION & BENEFITS 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.
