Founding Product Engineer
About the Role
This is a founding-level engineering role at a fast-moving B2B SaaS startup building an AI-native intelligence layer for strategic procurement. You will work across the full stack, from frontend interfaces to backend services and LLM agent pipelines, with direct ownership over features used by enterprise customers. The role matters because enterprise demand is outpacing current build capacity, and your output will immediately expand what the product can do.
What You'll Do
Prototype and ship full-stack features end to end, from UX through backend logic to prompt design.
Design and integrate LLM agent workflows that make sophisticated AI pipelines feel invisible and intuitive to end users.
Translate direct customer feedback and real-world usage signals into iterated product experiences.
Reason about system architecture and make pragmatic decisions across frontend, backend, and LLM integration layers.
Use AI coding tools fluently to accelerate development cycles while maintaining production-grade quality.
Work in person with the team in Berlin, contributing to a high-trust, high-velocity environment.
