Role Overview
We are looking for experienced Python Backend Engineers to work on an API migration initiative. The role involves migrating existing REST APIs from a Nuclio/Iguazio serverless workplace to Python + FastAPI microservices running on Kubernetes, while maintaining functional and API contract parity with the existing services.

Nuclio/Iguazio experience is mandatory. If Nuclio/Iguazio experience is not available, candidates must have strong and clearly demonstrated API migration experience, with detailed migration responsibilities visible in the resume. Simple API development experience will not be sufficient.
The engineer will work closely with the technical lead, QA, client SMEs, and platform teams to understand existing implementations, migrate business logic, integrate with existing backend systems, and validate migrated services.





Key Responsibilities
- Analyze existing Nuclio-based REST APIs, handlers, business logic, and dependencies.
- Migrate API business logic to Python/FastAPI microservices.
- Maintain functional and API contract parity with existing services.
- Work with existing shared libraries/SDKs and FastAPI frameworks.
- Integrate APIs with backend systems and data stores.
- Implement request validation, error handling, authentication/entitlement logic, and API transformations.
- Develop unit and integration tests for migrated services.
- Perform API contract and functional validation against existing services.
- Troubleshoot application, integration, and performance issues.
- Participate in code reviews, technical discussions, and design reviews.
- Prepare API/OpenAPI documentation and operational handover documentation.
- Follow established coding, CI/CD, security, and development standards.
