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. Find Jobs in Germany on Arbeitnow
