An early-stage AI startup seeking a Technical Co-Founder to automate the public tender process for architecture and engineering firms. You will own a core technical domain, building a generation engine for performance concept documents, a reference database, and LLM/RAG pipelines. This role requires strong full-stack engineering, LLM/NLP experience, and an entrepreneurial mindset. The position is equity-based and located in Berlin, Germany, with remote options within the DACH region.
This is a co-founder opportunity — not an employment contract. A pre-seed AI startup in the DACH region is automating the public tender process for architecture and engineering offices. These firms spend 3–5 unpaid working days on each of the 40–60 procurement procedures they handle annually — up to €110,000 per year in unrecoverable time. The platform cuts that burden by 70–90%, handling everything from tender discovery and go/no-go scoring to the automated generation of complete, office-branded performance concepts (25–35 pages per application).
The founding team currently consists of two people: one covering strategy, sales, and procurement law, and one Full-Stack & AI engineer. You would be the third co-founder, taking ownership of a core technical domain alongside the existing engineer.
The product is already live with an early customer, a second pilot is in preparation, and a public funding application (IBB Berlin ProFIT) is underway. The structural market opportunity is anchored by a multi-year, €500B German federal infrastructure programme that feeds public procurement pipelines through at least 2036.
