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'll work across the full stack — from React frontends to cloud infrastructure to LLM-powered backends — with direct influence over both the product and the engineering culture being built from the ground up. WHAT YOU'LL DO - Architect and ship end-to-end features, balancing near-term impact with long-term scalability. - Design agentic systems that use 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. - Proactively identify and resolve critical problems outside your immediate scope, from infrastructure bottlenecks to customer friction points. WHAT WE'RE LOOKING FOR - 3+ 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. - Strong proficiency with Python backend frameworks — FastAPI, Pydantic, and SQLAlchemy. - Production experience with TypeScript and React for building user interfaces for complex workflows. - Hands-on experience with agentic frameworks such as PydanticAI, Google ADK, LangGraph, or equivalent tools. - Experience designing mission-critical systems with high reliability, security, and data integrity requirements. - Comfortable shipping rapidly using AI coding assistants (e.g. Cursor, Copilot, Gemini) to increase velocity. - Experience with cloud infrastructure deployment and management for production applications. - Nice to have: Experience with LLM observability/evaluation tools, ERP or enterprise supply chain integrations, document extraction and unstructured data processing, or fluency in German. LOCATION Hybrid — Berlin, Germany. Visa sponsorship is not available.
