What do we need
We are seeking a Senior Full Stack .NET Engineer to support the team with exciting growth. You’ll build and maintain a variety of .NET Core applications—from WPF desktop clients to ASP .NET Core Web API/MVC backends and Minimal APIs—turning loosely defined product ideas into working software with a relentless focus on code quality. You’ll own features end-to-end (design → code → tests → docs), champion best practices (code reviews, static analysis, refactoring), check in regularly with the team, and occasionally work directly with customers to troubleshoot or refine requirements.

In this role you will get to:

Develop .NET Core solutions across WPF, ASP .NET Core (Web API/MVC, Minimal APIs) and related technologies

Translate high-level product requirements into detailed technical designs and implementation plans

Write thorough unit & integration tests (MSTest, NUnit/xUnit) and leverage Docker/Test Containers for reliable testing

Collaborate with PMs, QA, Dev Ops, and occasionally customers—to review designs, demo progress, and iterate rapidly

Maintain clean code, clear documentation, and version control (Git/Azure Dev Ops)

We are looking for
people who have 7+ years experience in C# / .NET Core along with 5+ years delivering production applications. Ideally with a degree in Computer Science or related engineering degree. You will be able to demonstrate advanced analytical skills with great attention to detail.

The key skills we are looking for:

Desktop & Web:
Hands-on with WPF and ASP .NET Core (Web API, MVC, Minimal APIs)

Blazor:
Web Assembly/Server component experience

Entity Framework Core: ORM usage, migrations, and performant data access

Testing:
Solid experience with MSTest (or NUnit/xUnit) and writing reliable automated tests

Async Programming:
Expert in async/await and task-based patterns

Visual Studio & Debugging:
Proficient with the IDE, debugger, and related tooling

Autonomy:
Able to take vague specs through design and delivery with minimal supervision

Code Quality:
Strong commitment to writing quality code with a focus on domain best practices, codebase standards, with an excitement for code reviews, static analysis (e.g., Sonar Qube/FxCop), and refactoring

You may also have

Docker & Test Containers:
Containerizing apps and test environments

Cloud

Infrastructure: Secure deployments on Azure/AWS/GCP

Security Best Practices: OWASP principles and secret management

CI/CD:
Azure Dev Ops or Git Hub Actions pipelines
