About the Role
This is a founding-team engineering role at an early-stage B2B AI startup in the construction technology space, sitting at the intersection of engineering and customer success. You'll own AI automation use cases end-to-end — from understanding enterprise customer problems to shipping production-ready solutions — with real influence over product direction and company trajectory from day one.
What You'll Do
-
Own new AI automation use cases end-to-end, from customer discovery through production deployment.
-
Turn ambiguous customer problems into scoped, buildable solutions and ship them within weeks.
-
Build with modern applied AI — LLMs, agentic workflows, vision models, embeddings, and heuristics — to solve high-impact enterprise problems.
-
Design and implement data pipelines for document ingestion, extraction, validation, and orchestration.
-
Identify recurring patterns across projects and codify them into reusable templates.
-
Work directly with enterprise stakeholders on-site to gather requirements and validate solutions.
-
Help shape the technical direction of both the product and the company.
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 — formal degree or clearly equivalent grounding.
-
Full-stack capability: backend API development (Node.js/TypeScript or Python) and frontend (TypeScript/React or similar).
-
Experience designing data pipelines for document processing, extraction, and validation with unstructured data (PDFs, images, documents).
-
Experience integrating multiple LLM providers (e.g. OpenAI, Azure, Gemini, Cohere) and solid prompt engineering skills.
-
Familiarity with vector databases, semantic search, or knowledge graphs is a plus.
-
Prior B2B experience, ideally in a customer-facing or requirements-gathering capacity.
-
Background in early-stage startups or founding teams; comfortable with ambiguity and rapid iteration.
-
C1+ German language proficiency — this role involves direct engagement with German enterprise stakeholders.
-
Pragmatic, action-oriented, and excited about applied AI over pure theory.
