Job description

Technical Skills

• Core .NET & C# Skills: A senior .NET engineer must have deep expertise in C# (generics, async/await, LINQ, reflection, delegates and events), the .NET ecosystem (Core / .NET 5+, Framework, Standard), ASP.NET Core (Web API, middleware pipeline, dependency injection, filters), and Entity Framework Core (migrations, query optimisation, relationships). Strong understanding of the CLR, memory management, and garbage collection is expected.
• Architecture & Design: They should be comfortable designing systems using SOLID principles, design patterns (Factory, Repository, CQRS, Mediator, Decorator), clean/hexagonal architecture, microservices, service‑oriented architecture, and domain‑driven design. Experience with API design (REST, GraphQL, gRPC) is increasingly important.
• Data & Storage: Proficiency with SQL Server (query tuning, indexing, stored procedures, transactions), ORMs (EF Core, Dapper), NoSQL databases (Redis, MongoDB, Cosmos DB), and basic data modelling.
• Cloud & DevOps: Hands‑on experience with at least one major cloud platform — Azure (App Services, Functions, Service Bus, AKS) is most common in the .NET world. CI/CD pipelines (Azure DevOps, GitHub Actions), containerisation (Docker, Kubernetes), and infrastructure‑as‑code (Bicep, Terraform) are expected at senior level.
• Testing & Quality: Strong unit testing (xUnit, NUnit, MSTest), integration testing, mocking (Moq, NSubstitute), TDD/BDD mindset, code review practices, and static analysis tools (SonarQube, Roslyn analysers).
• Security: Authentication and authorisation (OAuth 2.0, OpenID Connect, JWT, ASP.NET Identity), OWASP awareness, secrets management, and secure coding practices.
• Performance & Observability: Profiling and benchmarking (.NET Diagnostics, BenchmarkDotNet), distributed tracing and logging (Serilog, OpenTelemetry, Application Insights), and caching strategies.
