Back-End & Microservices * .NET 8 / ASP.NET Core (required): REST API development with minimal APIs or controller-based approaches, middleware pipelines, dependency injection, and configuration management. * C#: clean, idiomatic C# - LINQ, async/await, records, pattern matching. * Microservices patterns: independently deployable services, API contracts, loose coupling, domain-driven service boundaries, circuit breakers (Polly or equivalent). * Messaging: AWS SQS and SNS for asynchronous service communication; AWS EventBridge for event-driven patterns. * API design: RESTful design principles, OpenAPI/Swagger specification, API versioning, and documentation. * Authentication & security: OAuth 2.0, JWT, OWASP standards, PCI-DSS awareness for payment-adjacent services. AWS Hosting * AWS Lambda: serverless .NET 8 functions for event-driven compute, lightweight APIs, and scheduled tasks - using the AWS .NET Lambda runtime. * AWS ECS/Fargate: containerised .NET microservice deployments for longer-running or higher-throughput services. * Supporting AWS services: API Gateway, S3, CloudWatch, X-Ray, Parameter Store/Secrets Manager * Docker: containerisation of .NET microservices for ECS/Fargate deployment. DevOps & Engineering Practices * CI/CD: GitHub Actions - automated build, test (xUnit, Jest), lint, Docker build, and deployment pipelines. * Testing: xUnit and Moq for .NET unit and integration tests; Jest and React Testing Library for front-end; Playwright for end-to-end testing. * Version control: Git - branching strategy, pull request workflow, semantic versioning. * Observability: structured logging (Serilog or equivalent), AWS CloudWatch metrics and alarms, distributed tracing with AWS X-Ray. Beneficial * AI/conversational integration: OpenAI API or equivalent LLM integration for the AI concierge feature. * WhatsApp Business API and Amazon Connect integration experience. * Hospitality domain: iStay (CRS) and Maestro (PMS) API familiarity - useful but not required. ## Description Front-End Feature Development * Build and maintain features across Warner's guest-facing digital products using React and Next.js - implementing server-side rendering, static generation, and client-side interactions to the agreed architecture patterns. * Contribute to the continuous improvement of WarnerHotels.co.uk - search experience, IBE booking funnel, conversion optimisation, and promotional campaign delivery - in partnership with the commercial and marketing teams. * Build and maintain the MyWarner guest portal - delivering logged-in guest journeys including pre-stay upsell, activity booking, and in-stay engagement features. * Contribute to Club Warner loyalty platform features - enrolment flows, member personalisation, and loyalty mechanics - consuming APIs from back-end services. Back-End Microservice Development * Design and build .NET 8 / ASP.NET Core microservices that form the back-end of Warner's digital platform - implementing REST APIs, domain logic, and integration with Warner's core systems (iStay, Maestro, Bloomreach, Optimizely, Amazon Connect). * Deploy and operate microservices on AWS using a mix of Lambda (for event-driven and short-lived compute) and ECS/Fargate (for longer-running, containerised services) - selecting the appropriate hosting model for each service's requirements. * Implement event-driven communication between services using AWS SQS, SNS, and EventBridge - ensuring loose coupling and resilience across the microservices estate. * Contribute to integrations with the WhatsApp Business API via Amazon Connect for inbound customer engagement. API Design & Integration * Design RESTful APIs to agreed standards - implementing OpenAPI specifications, versioning, and API documentation for all services you build. * Work with the Integration Architect to ensure services are built to Warner's API governance standards and registered in the API catalogue. * Consume and integrate third-party APIs from Optimizely, Bloomreach, iStay, and Maestro - implementing appropriate error handling, retry logic, and circuit breakers. Engineering Quality * Write unit tests, integration tests, and end-to-end tests for all features and services - maintaining test coverage to agreed standards * Commit code through CI/CD pipelines (GitHub Actions) - following branching strategy, automated build, test, lint, and deployment processes consistently. * Participate in code reviews - providing constructive feedback to nearshore partners and internal colleagues, and actively responding to feedback on your own code. * Monitor production services and respond to incidents within your service domain - investigating root cause and implementing permanent fixes. Collaboration * Participate fully in sprint ceremonies - sprint planning, stand-ups, reviews, and retrospectives. * Work collaboratively nearshore engineering partner - sharing architectural context, reviewing their pull requests, and contributing to a high-performing cross-geography engineering culture. ## Related Videos - [How a Small Team Shrank a Microsoft Monorepo by 94%](https://www.wearedevelopers.com/videos/1236-how-a-small-team-shrank-a-microsoft-monorepo-by-94) - [Keeping applications secure by evolving OAuth 2.0 and OpenID Connect](https://www.wearedevelopers.com/videos/100152-keeping-applications-secure-by-evolving-oauth-2-0-and-openid-connect) - [100 million days in Vienna: A story of APIs & AI in tourism.](https://www.wearedevelopers.com/videos/93-100-million-days-in-vienna-a-story-of-apis-ai-in-tourism) - [Git for Code Reviews](https://www.wearedevelopers.com/videos/429-git-for-code-reviews) - [WeAreDevelopers LIVE – AI, Freelancing, Keeping Up with Tech and More](https://www.wearedevelopers.com/videos/1786-wearedevelopers-live-ai-freelancing-keeping-up-with-tech-and-more) - [Delay the AI Overlords: How OAuth and OpenFGA Can Keep Your AI Agents from Going Rogue](https://www.wearedevelopers.com/videos/1637-delay-the-ai-overlords-how-oauth-and-openfga-can-keep-your-ai-agents-from-going-rogue) ## Related Articles - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Dev Digest 132 - Binging WADFlix?](https://www.wearedevelopers.com/magazine/473-dev-digest-132-binging-wadflix) - [Dev Digest 133 - Back to Front](https://www.wearedevelopers.com/magazine/474-dev-digest-133-back-to-front) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Dev Digest 101 - the XXX edition](https://www.wearedevelopers.com/magazine/382-dev-digest-101-the-xxx-edition) - [Dev Digest 131 - AI'm not sure about OSS](https://www.wearedevelopers.com/magazine/472-dev-digest-131-ai-m-not-sure-about-oss)
