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.

Responsibilities

  • 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.

Requirements

  • 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.
