- Visa sponsorship is not available for this role.
- Hybrid working arrangement — approximately 3 days per week in the office.
Founding software engineer at an early-stage ConTech startup in Berlin. Hybrid ~3 days/week, C#/Python backend with CAD data focus, equity likely, no visa sponsorship.
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.
