Founding Engineer

Role details

ABOUT THE ROLE This is a founding engineering role at an early-stage AI startup building autonomous agents that automate complex processes for industrial enterprises. You will own the full stack, from React frontends to cloud infrastructure to LLM-powered backends, and directly shape both the product and the engineering culture from the ground up. WHAT YOU'LL DO - Architect and ship end-to-end features, balancing immediate impact with long-term scalability. - Design agentic systems that leverage LLMs for reasoning, document extraction, and enterprise process automation. - Implement AI best practices to ensure autonomous agents operate with precision, security, and industrial-grade reliability. - Own the complete user journey, refining frontends, architecting backend logic, and managing cloud infrastructure as needed. - Build mission-critical, secure, and resilient AI solutions held to the highest standards for data integrity and security. - Identify and fix critical problems outside your immediate scope, from infrastructure bottlenecks to customer friction points. WHAT WE'RE LOOKING FOR - 3 or more years building full-stack applications with Python backends and React frontends in production environments. - Practical production experience building and deploying LLM-based agentic systems or AI agents. - Proficiency with Python backend frameworks such as FastAPI, Pydantic, and SQLAlchemy. - Strong TypeScript and React skills for building intuitive interfaces for complex workflows. - Hands-on experience with agentic frameworks such as PydanticAI, Google ADK, LangGraph, or equivalent, plus solid prompt engineering fundamentals. - Experience designing and shipping mission-critical systems with high reliability, security, and data integrity requirements. - A pragmatic, ship-first mindset with comfort using AI coding assistants to accelerate development velocity. - Experience with cloud infrastructure deployment and management for production applications. - Familiarity with LLM observability, evaluation, or monitoring tools is a plus. - Experience integrating with ERP platforms or enterprise supply chain software is a plus. - German language fluency is a strong plus given the core industrial customer base. LOCATION This role is based in Berlin, Germany, and requires five days per week in the office. No visa sponsorship is available.
