HSL is a partnership between The Doctors Laboratory (TDL), Royal Free London NHS Foundation Trust and University College London Hospitals NHS Foundation Trust (UCLH). HSL was formed to provide pathology services to the NHS Trusts and has expanded further to provide services to other NHS Trusts. Over 3,500 staff work at Sonic Healthcare UK, primarily under the TDL or HSL banner. Our purpose is to deliver medically-led diagnostics, innovation, value and long-term investment to healthcare. With our core laboratory based at The Halo Building in London WC1H 9AX, we also have an expanding site in Manchester as well as smaller hospital-based laboratories across the country. We maintain rigorously high standards of quality, whilst also delivering efficiencies to healthcare through careful workforce planning, pioneering technology and significant investment in infrastructure and IT.

About the role

We are looking for an experience Senior Developer (Automated Testing), to help us raise the bar on quality for our next generation laboratory results system. The platform records patients' test results and makes it easier for doctors to get to the information that matters, so quality and reliability are non-negotiable.

C#.NET Core, Kubernetes (AKS), VueJS, Azure SQL, Database. Deployed via Azure DevOps (CI/CD). On the testing side, we have an established Cypress suite that we're planning to migrate to Playwright (TypeScript), and we use xUnit for backend unit and integration tests in C#.

Where will you work?

This is hybrid role based in London. We use Teams for meetings and instant messaging. Our head office is brand - new laboratory near Kings Cross. It's one of the biggest diagnostic labs in Europe with advanced robotic systems and high spec lab facilities covering everything from blood sciences to genetic testing. We may ask that you visit our labs to understand what we do, but that's not often.

What are we doing?

Hospital lab systems are very niche, so haven't evolved much over the years. There is enormous scope to innovate in this area. We have built a solid web platform deploying to Kubernetes services in Azure. The system has been running the labs for multiple hospitals across London for few years. It connects up to the machines that run our blood tests and to the hospital systems to send results to patients.

As the platform grows, we want automated testing to be a first class part of how we build and ship software. You will own the migration from Cypress to Playwright our end to end coverage of the journeys that clinicians and lab staff rely on everyday, and expand xUnit coverage across the. NET services so that CI gives fast, trustworthy feedback. You will join a team with three developers, an IT operations team and many experienced scientists.

You take quality personally. You enjoy designing tests as much as writing code, and you think about edge cases long before bugs reach production. You're fluent writing browser tests in TypeScript and comfortable jumping into a C# codebase to add xUnit coverage where it's missing. You should be the kind of person who takes ownership of the test estate and actively looks for ways to improve it, whether that's coverage, flakiness, CI runtime, or developer experience of running tests locally. You write your test code clearly and in a way that other developers can pick up, support and extend.
