Join a world-class team of engineers at Grid Dynamics as we build mission-critical engineering tools. We are hiring an ownership-driven Backend Developer to architect the Python-based workflow engines and state machines that bridge the gap between complex hardware requirements and streamlined digital approvals.
Essential functions
- Design and implement high-performance, asynchronous Python backend services using FastAPI and asyncio to power complex review workflows.
- Translate intricate business logic into robust state machines, managing requirement transitions from Draft through Active to Approved/Rejected states.
- Build and maintain the integration layer with JAMA Connect’s REST API, ensuring seamless data synchronization and handling edge cases like rate limiting and retries.
- Serve as the primary architect for the client-server contract, collaborating with Swift/macOS engineers to define JSON schemas, error codes and status enums.
- Design relational database schemas in PostgreSQL that support comprehensive audit trails and versioned records for every approval decision.
- Maintain high code quality through rigorous pytest coverage and document the API lifecycle to ensure long-term maintainability for QA and future engineers.
Qualifications
- Proven experience with async I/O patterns (FastAPI, asyncio, or aiohttp) and a deep understanding of writing non-blocking, scalable code.
- Strong background in designing and consuming RESTful APIs, including experience with pagination, error handling, and third-party service integrations.
- Advanced skills in PostgreSQL, specifically in schema design for version tracking, complex migrations, and high-integrity audit logs.
- Demonstrated experience building state machines or complex workflow engines involving multi-step approvals and status transitions.
- A "test-first" mindset with professional experience using pytest for unit and integration testing against both mock and live endpoints.
Would be a plus
- prior experience working with JAMA Connect, IBM DOORS, or similar ALM (Application Lifecycle Management) tools
