.NET software engineer

We're looking for a .NET software engineer to join our small team building the platform that powers Koala Legal, a modern conveyancing firm based in Sheffield.

You'll work across the full stack: server-rendered Razor Pages, PostgreSQL, Azure Container Apps, and a Tailwind CSS frontend enhanced with Alpine.js and Alpine-AJAX for partial page updates without full reloads. No SPAs, no GraphQL, no microservices for the sake of it. We use server-side rendering because it's the right tool for the job, and we keep things simple because simple systems are reliable systems.

This is a greenfield platform built from scratch in 2026. There's no legacy to wrestle with, but there's plenty to build. You'll ship features end-to-end, from writing the EF Core migration to deploying via our GitHub Actions pipeline.

You don't need to tick every box. We care more about how you think than what you've memorised.

• $ Strong experience with C# and .NET (ASP.NET Core, EF Core)
• $ Comfortable with relational databases (PostgreSQL or SQL Server)
• $ You write clean, readable code and care about getting the domain model right
• $ Happy working across the stack, including HTML, CSS, and a bit of JavaScript
• $ You prefer simple solutions and know when not to add an abstraction
• $ Bonus: experience with Azure, Docker, IaC, or CI/CD pipelines

We deploy to production multiple times a day. Every migration is backwards-compatible for zero-downtime rollouts. We use feature branches, pull requests with preview environments, and automated pipelines that build, test, and deploy.

We don't have a QA team. Engineers own what they ship. We write tests where they matter and use server-side validation everywhere. We keep dependencies minimal and don't reach for a library when 20 lines of code will do.

We pair when it helps. We work independently when it doesn't. No standups for the sake of standups.
