Founding Engineer

About the Role

This is a founding engineering role at an early-stage AI startup building autonomous agents that automate complex processes for industrial enterprise customers. You will architect and ship features across the full stack, from React frontends to LLM-powered backends to cloud infrastructure, and play a direct role in shaping both the product and the engineering culture.

What You'll Do

• Architect and ship end-to-end features, balancing immediate 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 high standards for data integrity.
• 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.
• Hands-on 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.
• Practical experience with agentic frameworks such as PydanticAI, Google ADK, or LangGraph, and prompt engineering.
• Experience designing and shipping mission-critical systems with high reliability and data integrity requirements.
• Comfort using AI coding assistants (such as Cursor, Copilot, or Gemini) to ship features rapidly.
• Experience with cloud infrastructure deployment and management for production applications.
• Experience 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.
