Senior Software Engineer (m/f/d) Production Platforms

Your mission

• You build and evolve the operations platform and shopfloor tablet app for goods receipt, inventory and outbound logistics.
• You work with operations to turn an initial request into a clear, proportionate scope, and you recommend holding or declining work when the expected value does not justify the effort.
• You steer our AI development setup and assess the agent’s output carefully and bring your own judgment to decisions about architecture and correctness.
• You move between backend and frontend development: Python with FastAPI and async SQLModel on PostgreSQL, alongside React and TypeScript.
• You integrate the platform with SAP S/4HANA, Microsoft Entra ID and shopfloor label printers.
• As the platform expands, you strengthen the practices that keep it maintainable. Automated testing, observability and deployment automation are already in place.
• You make architectural choices, capture the reasoning in accessible documentation and contribute thoughtful feedback in code reviews.

Your profile

• You have built software for production use and supported it after release.
• You have practical experience building Python services with an asynchronous web framework, modelling relational data and managing database migrations.
• React and TypeScript are part of your hands-on toolkit, and you are comfortable building complete user interfaces.
• You use Docker and CI in your daily development work and you are comfortable working with Linux servers. Experience with configuration management, reverse proxies and networking is an advantage.
• You can assess AI-generated code and recommendations on their technical merits and make engineering decisions based on your own technical judgment.
• You can turn an unclear operational need into a specific software requirement and discuss it directly with production colleagues.
• You communicate confidently and fluently in German and English, including technical discussions with colleagues on site.
• Experience in production, logistics or the process industry is a strong plus.
