Original job description

Our client is seeking a hands-on Senior Platform Software Engineer (Backend) to implement shared cloud-native services and reusable .NET SDKs for a next-generation enterprise application platform. The role focuses on security, API standards, session management, resilient integrations and developer enablement across independently delivered domain services.

Platform engineering

 Build shared services, middleware, templates and reusable NuGet SDKs using C#, modern .NET and ASP.NET Core.

 Implement authentication integration, BFF session management, token lifecycle controls and tenant-aware, resource-level authorization patterns.

 Establish API standards for validation, versioning, structured errors, idempotency, configuration and service-toservice integration.

 Develop reusable patterns for PostgreSQL access, Redis caching/session storage, observability and resilient messaging as appropriate.

 Contribute to AWS-based deployments, including API Gateway, ECS/Fargate, Aurora/RDS PostgreSQL, ElastiCache, SQS and EventBridge where relevant.

 Publish packages through Azure DevOps Artifacts and support domain teams in adoption without unnecessary coupling.

AI-assisted development and quality

 Use Claude Code or comparable AI coding assistants for design exploration, implementation, refactoring, testing and documentation.

 Apply structured, specification-driven AI-assisted delivery approaches, including AWS AI-DLC 2.0; turn requirements into reviewable plans and acceptance criteria.

 Review and verify AI-generated code for security, correctness, maintainability and compliance with platform standards.

 Contribute to Azure DevOps CI/CD pipelines, automated tests, peer reviews and engineering quality gates.

Required qualifications

 Typically 5+ years of professional backend engineering experience, or equivalent demonstrated capability.

 Strong C#, modern .NET, ASP.NET Core and secure REST API development experience.

 Solid knowledge of OAuth 2.0, OIDC, application security, authentication and authorization.

 Experience with SQL/relational databases, transactions, asynchronous programming and failure-resistant service design.

 Experience with AWS or comparable cloud platforms, automated testing, Git and CI/CD.

 Ability to contribute to architecture and implement production-grade components independently.

Preferred qualifications

 AWS ECS/Fargate, API Gateway, Aurora PostgreSQL, ElastiCache, SQS, EventBridge, Secrets Manager and CloudWatch.

 BFF patterns, enterprise federation (Entra ID/PingFederate), Redis, multitenant authorization and OpenTelemetry.

 Transactional outbox/inbox, event versioning, duplicate-message handling, Flyway, Terraform and Azure DevOps Artifacts.

 Demonstrable hands-on use of Claude Code, GitHub Copilot or similar AI tools; familiarity with AWS AI-DLC 2.0.

Expected deliverables

 Production-ready shared backend components and versioned .NET SDKs.

 Reference services, secure authentication/session and authorization integration patterns.

 Automated tests, pipeline integration, operational instrumentation and adoption documentation.
