Project description

The programme is building a resilient, secure, production-grade platform of Python backend services, REST APIs, asynchronous processing components and external integrations, backed by MongoDB and delivered through a React/TypeScript operational user interface with auditable operations and role-based enterprise user journeys. As an experienced Python engineer, you will develop the platform's backend services, APIs, processing components and external integrations, with emphasis on asynchronous execution, resilience, data validation, automated testing and production-quality engineering.

Responsibilities

Design and build maintainable Python services and REST APIs. Implement asynchronous workers and non-blocking integration patterns.

Create typed domain models and validate complex JSON/API payloads.

Engineer timeouts, retries, backoff, idempotency and failure recovery.

Integrate securely with MongoDB and external services.

Create comprehensive unit, component and integration tests.

Support code reviews, engineering standards, CI/CD and production troubleshooting.





Contribute to design decisions and support B8 engineers.
