About the projectWe're looking for a Backend Developer Python to build and evolve the internal platform that supports the AI team of a leading client in the renewable energy sector.It's an event-driven platform that needs to handle variable load, recover from failures without manual intervention, and scale at the pace demanded by a fast-growing AI team.What you'll do- Design, build, and maintain Python backend services within an event-driven architecture.- Design and manage queues and consumers (RabbitMQ): load balancing across consumers, retry and failure-recovery strategies, handling messages that can't be processed.- Containerize services with Docker and take part in deployment infrastructure decisions.- Work directly alongside the platform's AI team, understanding their consumption needs and integrating their work into the backend.- Contribute to architecture decisions: integrations between microservices, dependency management, and packaging.Requirements (must-have)- Solid Python experience in production environments, with at least one of these frameworks: FastAPI, Django,



or Flask (experience with async frameworks is especially valued).- Real experience building or maintaining event-driven architectures / distributed systems with message queues (RabbitMQ, Kafka, or similar).- Ability to explain, with real judgment, how consumer failures are handled: what happens when a message can't be processed, how to prevent it from blocking the queue and affecting the rest of the system, and what retry/discard strategies are applied.- Experience creating your own Dockerfiles and working with Docker Compose; solid understanding of what a Docker layer is and how it works.- Experience working with microservices and their integrations (APIs, queues, events).- Comfortable with Python dependency management (pip, PyPI; experience with uv is aplus).Nice-to-have- Experience with Apache Airflow for workflow/pipeline orchestration.- Integrating uv inside a Dockerfile.- Experience with AI agents or agentic systems.- Regular use of AI as part of your own development workflow (Cursor, Claude Code) — not just code generation, but critical review and validation of generated code.- Prior experience in energy or industrial sector projects.#J-18808-Ljbffr
