About this role
About the Role
This is a founding-team engineering role at an early-stage construction technology AI startup, sitting at the intersection of engineering and customer success. You will own AI automation use cases end-to-end, from scoping problems with enterprise customers through to shipping production-ready solutions, and have real influence over product direction and company culture from day one.
What You'll Do
- Own AI automation use cases end-to-end, from customer discovery through production deployment.
- Turn ambiguous enterprise customer problems into scoped, buildable solutions and ship them quickly.
- Build with modern applied AI, including LLMs, agentic workflows, vision models, and embeddings, to solve high-impact problems.
- Design and implement data pipelines for document ingestion, extraction, validation, and orchestration.
- Identify recurring patterns across projects and codify them into reusable, scalable templates.
- Balance speed, accuracy, and pragmatism, knowing when to keep humans in the loop.
- Visit customers on-site and work directly with German-speaking enterprise stakeholders to gather requirements.
- Help shape the technical direction of both the product and the company as an early hire.
What We're Looking For
- 2 or more years of experience as a software engineer or data scientist building production systems.
- Hands-on experience deploying applied AI solutions (LLMs, agentic workflows, vision models, embeddings) in production.
- Strong CS fundamentals, through a degree or clearly equivalent formal grounding.
- Full-stack capability: backend API development in Node.js/TypeScript or Python, and frontend development in TypeScript/React or similar.
- Experience designing data pipelines for document processing, extraction, and validation with unstructured data (PDFs, images, documents).
- Experience with vector databases, semantic search, or domain ontologies.
- Comfortable integrating multiple LLM providers (such as OpenAI, Azure, Gemini, or Cohere) and writing effective prompts.
- Proven ability to own problems end-to-end, from requirements gathering through deployment.
- B2B experience with enterprise stakeholders, and a background in early-stage startups or founding teams.
- C1-level German proficiency or above (this is a customer-facing role with German enterprise clients).
- Comfortable with travel to customer sites and working fully on-site in Berlin five days a week.
