Job description

About The Role

We are looking for a Full Stack Developer who is strong on the backend with .NET Core and comfortable working across the application in Angular or React when the feature demands it. You will build and run REST APIs and business logic for enterprise clients, work directly with SQL Server, and take features from API contract through to UI without handing off at the boundary.

Key Responsibilities

• Build and maintain backend services using .NET 8 / ASP.NET Core - REST APIs, business logic, background jobs and integrations with third-party systems.
• Design and work with SQL Server - schemas, queries, stored procedures, indexing, and reading an execution plan to explain why something is slow.
• Develop frontend features in Angular 16+ or React 18+ - reusable components, forms and validation, typed API clients, predictable state management, and clean integration with backend APIs.
• Deliver features end to end - API contract, data access, UI, tests and deployment - rather than stopping at the layer boundary.
• Maintain and incrementally modernise existing ASP.NET MVC applications, moving logic into services and APIs without destabilising what is already in production.
• Debug production issues using structured logs, traces and metrics (Application Insights, Serilog); find the root cause, ship the fix, and add the test that would have caught it.
• Write secure, maintainable code - input validation, parameterised queries, correct error handling, structured logging, and no secrets in source control.
• Use AI coding assistants (GitHub Copilot, Claude Code) as a daily tool - and be able to explain, test and defend everything you raise in a pull request.
• Write unit and integration tests (xUnit / NUnit on the backend; Jasmine / Karma, Jest or Vitest on the frontend) and keep the CI pipeline green.
• Participate in code reviews and technical discussions as both an author and a reviewer.
• Work closely with product, QA and DevOps through the sprint, from grooming to release.

Mandatory Requirements

• 3+ years of hands‑on development experience in a product or enterprise delivery environment.
• Strong C# and .NET Core / ASP.NET Core - dependency injection, middleware pipeline, async/await, configuration and options.
• Practical REST API experience - status codes, versioning, pagination, error contracts and authentication headers.
• Hands‑on SQL Server - joins, stored procedures, indexes, and the ability to read a query plan.
• Working experience with Entity Framework Core or Dapper.
• Strong TypeScript, with production experience in either Angular (v15 or later) or React 18+ - component design, routing, forms and validation, state management, and HTTP / API integration.
• Good experience with ASP.NET MVC and legacy application maintenance.
• Solid grounding in OOP, SOLID and common design patterns.
• Git‑based workflow - branching, pull requests, code review and conflict resolution.
• Strong debugging and problem‑solving skills - able to work from a stack trace to a verified fix.
• Clear written and spoken communication in a distributed, client‑facing team.
