About the Role
This is a founding-team engineering role at a construction technology AI startup, sitting at the intersection of engineering and customer success. You will own new AI automation use cases end-to-end, from discovery with enterprise stakeholders through production deployment, and have real influence over what gets built and how the company scales.
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.
-
Design and implement data pipelines for document ingestion, extraction, validation, and orchestration.
-
Identify recurring patterns across projects and codify them into reusable templates.
-
Balance speed, accuracy, and pragmatism, keeping humans in the loop where appropriate.
-
Travel to customer sites and work directly with German enterprise stakeholders.
-
Help shape the technical direction of both product and company as an early hire.
What We're Looking For
-
2+ 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, from 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 workflows.
-
Comfortable working with unstructured data (PDFs, images, documents), vector databases, and semantic search.
-
Experience integrating multiple LLM providers (such as OpenAI, Azure, Gemini, or Cohere) and solid prompt engineering skills.
-
B2B experience, ideally in a customer-facing technical role with direct enterprise engagement.
-
Experience in an early-stage startup or founding team environment.
-
C1-level German proficiency or above (required for enterprise customer interaction and on-site visits).
-
Bonus: familiarity with domain ontologies, knowledge graphs, or construction industry workflows.
Compensation & Benefits
Salary range: 72,000 to 100,000 EUR annually. Visa sponsorship is not available for this role.
Location
On-site, 5 days per week in Berlin, Germany, with occasional travel to customer sites across the region.
