You will own the middleware layer: secure APIs, Azure API Management policies, real-time order and inventory sync, and the reliability patterns that keep a customer-facing app fast during peak trading.\n\nLocation: Remote / hybrid (to be confirmed by client)\nType: Full-time or contract\nExperience: 6–10 years in backend development, at least 3 in integration-heavy roles\nReports to: Integration / Solution Architect\n\nKey responsibilities\nBuild and maintain backend APIs in .NET 8/9 (ASP.NET Core) that serve the POQ mobile app: product catalogue, pricing, basket, checkout, customer account, loyalty and order history, built on SAP Commerce OCC REST APIs.\nDesign real-time commerce integrations that sync orders, inventory and stock availability between SAP Commerce Cloud, ERP/OMS and the warehouse system (WMS), using event-driven patterns (Azure Service Bus, Event Grid, Functions, webhooks).\nOwn Azure API Management (APIM): write and maintain policies for JWT validation, rate limiting and quotas, caching, request/response transformation, CORS, IP filtering, backend routing and retries.\nSecure the platform: validate JWT/OAuth 2.0 / OpenID Connect tokens server-side (signature, issuer, audience, expiry, key rotation via JWKS), and keep all secrets in Azure Key Vault accessed through Managed Identity.\nEngineer for failure: implement timeouts, retries with exponential backoff and jitter, circuit breakers, rate-limit handling (HTTP 429 / Retry-After) and dead-letter queues using Polly / Microsoft.Extensions.Resilience.\nGuarantee data integrity: make sync processes idempotent (idempotency keys, upserts, de-duplication, outbox pattern) so duplicate or out-of-order messages never create double orders or wrong stock.\nOptimise performance: call independent downstream APIs in parallel (async/await, Task.WhenAll), manage HttpClient correctly via IHttpClientFactory / typed clients, and keep mobile response times low.\nAccelerate delivery with code generation: generate API clients and models from OpenAPI/Swagger specs (NSwag, Kiota, AutoRest, Refit) rather than hand-writing them.\nModernise legacy code: support existing .NET Framework 4.8 services and plan their migration to modern .NET.\nOperate what you build: monitoring and alerting with Application Insights / Azure Monitor, CI/CD with Azure DevOps or GitHub Actions, and production support during peak trading.","description_format":"text","description_chars":2610,"description_truncated":false,"requirements":{"experience_years_min":6,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial
