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.
