Job description

10+ years in API, integration or backend engineering, including 3+ years owning API architecture and design at an enterprise scale.
Strong hands-on Java with Spring Boot and Spring WebFlux / Project Reactor: reactive streams, backpressure, non-blocking I/O, and streaming large payloads and files without exhausting memory.
Deep API design skills: REST and OpenAPI, contract-first development, versioning, pagination, error and status-code semantics, and idempotency.
Secure file-transfer patterns at scale, including SFTP, signed URLs, and multipart and resumable uploads and downloads.
Proven ability to design and architect, not just build: you can produce target-state designs, sequence diagrams and interface specifications, and defend the trade-offs to a client architecture forum.

Hands-on API Delivery In An Azure Environment

Compute and hosting: App Service, AKS or Container Apps, with containerised deployment.
Azure API Management for gateway policies, throttling, subscriptions and developer portal.
Entra ID, managed identities, RBAC, Key Vault and private endpoints.
Messaging and event-driven integration with Azure Event Hubs, Service Bus or Kafka.
Working knowledge of Python for automation, testing and operational tooling around the API estate.
Strong SQL and data modelling, plus schema and contract design for integration.
CI/CD and IaC in anger: Git branching strategy, automated pipelines in Azure DevOps, Terraform, and automated contract and integration testing.
Clear technical writing, and the ability to present and defend a design to both engineers and non-technical stakeholders, including client-side teams.
