Lead Full Stack Engineer (Berlin)

GeneralMind builds AI Systems of Action for complex enterprise workflows. We deploy AI employees that automate messy operational handovers across supply chains - processing orders, validating invoices, coordinating suppliers, and handling exceptions directly on top of enterprise systems like SAP, Oracle, JDE, and Dynamics. Our platform combines AI agents, operational context graphs, and real transaction data to achieve Autopilot-grade automation in real operational environments. We work closely with leading global companies across manufacturing, retail, and logistics to deploy AI into mission-critical workflows. Tasks Design, build, and evolve production-grade full-stack applications using Python (FastAPI) and React (Next.js). Architect and develop next-generation interfaces for our Systems of Action, enabling seamless human-in-the-loop interactions and complex data visualization. Build durable backend workflow systems using tools like Temporal to support asynchronous AI agent execution. Improve reliability, observability, and operational tooling across both client and server applications. Integrate with enterprise systems such as ERP platforms (SAP, Dynamics, etc.) and external APIs, surfacing that data intuitively on the frontend. Scale multi-tenant systems, database architectures (PostgreSQL), and platform abstractions. Work closely with product and forward-deployed engineering teams to translate real customer problems into cohesive end-to-end features. Requirements Strong full-stack engineering fundamentals and production experience owning end-to-end feature delivery. Deep experience with React and modern frontend ecosystems, coupled with a strong eye for user experience and interface design. Deep experience with Python and distributed / backend systems. A strong ownership mentality and systems thinking - you care just as much about UI state management as you do about backend database query optimization. Ability to design reliable, observable, maintainable sy
