Job description

About the Role This is a founding-team engineering position at a pre-seed AI-powered SaaS startup operating in the construction technology (ConTech) space. As one of the first engineers, you will own the product technically from day one - partnering directly with the founders to build a category-defining platform that automates project documentation, decision tracking, workflow management, and risk analysis for the construction industry. You will have end-to-end ownership across the full stack, from data models and backend systems to intuitive, responsive user interfaces, with direct and visible impact on customer outcomes in a rapidly evolving market. Important: German language proficiency is a hard requirement for this role. What You'll Do • Build customer-facing features spanning database design through beautiful, responsive frontends. • Design robust, scalable systems capable of handling complex workflows and large, real-world datasets. • Ship code fast - work in a high-velocity environment where ideas go from concept to production in days. • Build sophisticated data workflows leveraging AI and vector data capabilities. • Collaborate closely with founders to shape product direction and key technical decisions. What We're Looking For Required skills & experience: • Fluent German speaker (hard requirement). • Strong proficiency in TypeScript and Next.js for full-stack development. • Hands-on experience with PostgreSQL and Supabase, including vector data. • Familiarity with LangChain, TanStack Query, and shadcn UI for building UIs and data workflows. • A track record of stable tenure - preferably roles lasting 12+ months (internships excluded). • Strong computer science fundamentals; a university degree is valued but not required. Nice to have: • Prior experience in a startup environment, shipping features rapidly. • Experience in or knowledge of the construction or project management industry. • Ability to take full end-to-end ownership from database to UI with a direct eye on customer impact. • Collaborative, founder-ready mindset - comfortable contributing to product and strategic decisions. Location & Work Arrangement This role is based in Munich, Germany and follows a hybrid working model. You are expected to be in the office at least three days per week, with flexibility to work remotely for a few weeks at a time. Visa sponsorship is not available for this position. Compensation & Benefits • Salary: €70,000 – €90,000 per year, depending on experience. • Early-stage equity opportunity as a founding team member. • High autonomy and direct influence over product and technical direction. • Work on a genuinely novel problem at the intersection of AI and construction technology.
