Senior Backend Python Developer

About the Position

We are seeking a Senior Backend Python Developer with expertise in Python 3.10 to develop backend services and APIs for our CryoFlow project.

Responsibilities

• Contribute to the refactor of existing backend capabilities into Python 3.10 services aligned with CryoFlow architecture and deployment practices.
• Create and maintain BFF services using FastAPI and Uvicorn, exposing clear API routes for product workflows, integration screens, and front-end consumers.
• Help define service boundaries in a microservice architecture, with a pragmatic approach to simplifying or consolidating backend services when it improves maintainability.
• Integrate workflows into CryoFlow, including vitrification experiments, worklists, grid details, user/session consistency, and navigation between application contexts.
• Help the team design, implement, and deliver new product features after the initial integration work, with ownership from analysis to tested delivery.
• Implement backend logic for status updates, validation, data persistence, device/session edge cases, report-generation helpers, and user-facing error handling.
• Collaborate with front-end developers on Angular integration; Angular v17 or similar modern Angular experience is a strong plus for debugging and small feature delivery.
• Write and maintain tests for Python services and integration flows, including API tests, BFF route tests, mocked external calls, and regression tests for known issues.
• Investigate and fix product behavior issues by reading logs, reproducing scenarios, checking data consistency, and validating fixes end to end.
• Work with DevOps and CI/CD owners on deployment-related needs such as Docker images, pipeline behavior, SBOM/release build expectations, and environment validation.
• Use Kubernetes knowledge when available to inspect pods, readiness/liveness behavior, service health, configuration, and deployment problems in DEV or integration environments.
• Document API behavior, BFF responsibilities, and known edge cases so the team can operate and evolve the integrated product sustainably.

Requirements

• Must have

  • 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.

• Nice to have

  • Angular v17 experience is a major plus, especially for integrating BFF routes with user workflows and helping with front-end debugging.
  • Experience with Kubernetes basics: pods, services, logs, readiness/liveness probes, ConfigMaps, 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.

We Offer

• Competitive salary
• Opportunity to work on cutting-edge projects
• Professional development opportunities
