Your role with us

You will be responsible for the services and interfaces of our platform: from clean schema design in PostgreSQL and TimescaleDB to efficient API logic with Python and FastAPI, all the way to testing, observability, and CI/CD. You will take a holistic approach to architecture, actively shape technical changes, and develop into a reliable sparring partner within the team. 

Together with Embedded Systems, Customer Excellence, and Analytics, you will translate business and technical requirements into reliable, well-tested services. With automated tests, high code quality, traceable documentation, and clear guardrails, you will ensure that new features are deployed safely and reliably to production.

Your tasks

• Development, maintenance and optimization of backend services, REST APIs and automations based on Python.
• Design and maintenance of data models in PostgreSQL and TimescaleDB - including queries, indexes and migrations.
• Participation in architectural decisions regarding API structure, service layers and interfaces, as well as comprehensible documentation of the decisions.
• Further development of MQTT-based communication between gateways and backend, as well as the associated message processing.
• Ensuring and further developing quality standards and production stability
• Close collaboration with embedded systems, analytics and other product roles, as well as support for requirements up to stable handover into production.

This is what you bring with you

• Excellent Python practice for backend development, data processing, and API logic.
• Expertise in automated testing and the development of quality standards, as well as a structured, reproducible way of working with tickets and agile processes with a focus on security and clean code.
• Experience with relational databases, ideally PostgreSQL/TimescaleDB (schema design, indexing, migrations).
• Safe handling of REST interfaces and clean, versioned documentation.
• Familiarity with modern backend frameworks (e.g., FastAPI).
• Experience with Git, GitLab, CI/CD and containerized development or production environments, especially Docker.
• Willingness to familiarize yourself with new topics, take on responsibility and actively participate in shaping technical changes in exchange with other team roles.
