Role Description We are looking for experienced Python developers to join our engineering team and help us create dynamic software applications for our clients. In this role, you will be responsible for building a Backend for Frontend (BFF) service to power a new React Native mobile application. You will join a cross-functional team, working alongside frontend, cloud, and test engineers to implement a production-grade Python BFF that bridges mobile clients with enterprise backend services. - Assess and determine the viability of an existing AI-generated BFF codebase as a starting point - Implement and extend the BFF using FastAPI, contributing hands-on alongside the mid-level developer - Integrate with a custom-built internal OAuth2 auth service backed by an Oracle identity database, with a future migration path to AWS Cognito - Integrate with backend APIs via Azure APIM using Entra B2B service-to-service authentication - Acquire, cache, and refresh tokens for downstream API calls - Orchestrate and aggregate multiple backend service responses into mobile-optimised payloads - Implement resilience patterns: circuit breakers, retries with exponential backoff, and timeouts - Design and enforce authorisation policies (RBAC/ABAC - exact model TBD) - Set up structured logging, distributed tracing, and metrics using Grafana / Grafana Faro - Implement rate limiting, input validation, and secure data handling - Integrate with a feature flag service once defined (potentially a custom-built solution) - Contribute to CI/CD pipeline configuration (GitHub Actions) - Contribute to Terraform IaC alongside the client's dedicated cloud team - Collaborate with principal engineers to define an API versioning strategy for mobile backward compatibility Technical Context - BFF will be containerised and hosted on AWS (specific service TBD - App Runner, ECS, or EKS) - Dual-cloud environment: AWS is the primary platform; Azure is used for APIM and Entra ID - Some backend APIs will be available at the start; others will be built in parallel by internal teams during the engagement - Caching layer not yet defined - likely AWS-based (e.g. ElastiCache) - Observability: Grafana / Grafana Faro (migrating away from Datadog and Google Analytics) - IaC: Terraform, with support from a dedicated cloud team - CI/CD: GitHub Actions (confirmation pending) - Streaming (WebSocket/SSE) is on the product roadmap but is not a near-term deliverable Qualifications - 5+ years Python development with strong async programming (asyncio) - Proven production experience with FastAPI or a comparable async Python framework - Solid understanding of OAuth2/OIDC flows and token lifecycle management - Experience integrating with Azure APIM and Entra ID for service-to-service auth - Knowledge of distributed systems resilience patterns: circuit breakers, retries, bulkheads - Experience designing REST APIs for mobile consumption: response shaping, batching, payload optimisation - Security-first approach: TLS enforcement, rate limiting, input validation, data masking - Observability experience: structured logging, metrics, and distributed tracing - Comfortable reviewing and making quality judgements on an existing codebase - Comfortable working in a CI/CD environment (GitHub Actions or equivalent) Nice to Have - Experience with AWS Cognito or custom OAuth2 provider integration - AWS container hosting experience (ECS, EKS, App Runner, or similar) - Grafana stack experience — Grafana Faro, Loki, Tempo - Redis or ElastiCache caching experience - Terraform familiarity - Prior experience implementing a BFF or API Gateway pattern - Familiarity with React Native or mobile-first API design - WebSocket or SSE implementation experience
