You're a strong full-stack engineer. You build complex, performant frontends in TypeScript and React/Next.js and the backend APIs behind them, and you have real instincts for database design and query optimization, because construction data is deeply interconnected. You prototype fast and measure everything. You also care about reliability, because on a live construction project, wrong has consequences. Level is open. If you're exceptional, we'll build the scope around you. Nice to have, not required: comfort integrating AI features even if you don't build the models yourself, strong open-source work, an earlier stint as an early employee at a startup, domain depth in construction or complex B2B workflows, or a good eye for design so you can build clean interfaces without detailed mockups. We work in English. German helps for customer calls but isn't required. We have native speakers for that.
