Python Backend Engineer

Mandatory Skills

• Solid Python development experience, ideally with Python 3.10 in backend services or API-oriented applications.
• Hands-on experience with FastAPI and Uvicorn, including route design, validation, dependency injection patterns, async behavior and operational logging.
• Experience creating or maintaining BFF layers that adapt backend/domain services for front-end workflows.
• Good understanding of REST APIs, data validation, error handling, service-to-service calls and backend integration testing.
• Familiarity with microservice architecture and the trade-offs around splitting, combining or simplifying services.
• Ability to debug product issues across backend code, API responses, logs, databases, front-end symptoms and deployment state.
• Strong autonomy and ownership, with enough communication discipline to keep product, QA and other developers aligned.
• A practical testing mindset: unit tests, API tests, integration tests, mocks/fixtures and regression checks for realistic product scenarios.

Preferred skills

• Angular v17 experience is a major plus, especially for integrating BFF routes with user workflows and helping front-end debugging.
• Experience with Kubernetes basics: pods, services, logs, readiness/liveness probes, config maps, secrets and deployment troubleshooting.
• Experience with Docker and CI/CD pipelines, especially for Python services, release builds, SBOM generation and automated test execution.
• Experience helping a team develop a product after initial delivery, including triage, reproduction, root-cause analysis and close collaboration with QA.
• Knowledge of authentication/session handling, token refresh and multi-user edge cases.
• Familiarity with scientific, device-driven or laboratory workflows where state transitions and data consistency are important.
