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.
