Senior Test Engineer

Join a high-performing engineering squad working on complex backend microservices that power large-scale digital customer experiences. This is a great opportunity for a Senior Test Engineer – or a strong Intermediate looking to step up – to play a key role in uplifting automation, improving test coverage, and ensuring quality across a cloud-native, microservices-based environment.

About the Role

You’ll join the Messaging Squad within a modern cloud environment, working closely with Developers, QA, SRE, Product and Architecture teams. Your focus will be on both manual and automated testing across backend microservices, with a strong emphasis on C# automation and API-level testing.

The role is available now, and the team is ready to onboard the right person as soon as they’re able to start.

What You’ll Be Doing

• Designing, developing, and executing automated tests using C#
• Expanding and maintaining automation frameworks
• Conducting API, integration, backend and microservices testing
• Completing manual testing where required (approx. 40%)
• Identifying, raising, triaging and documenting defects
• Collaborating with Developers, Team Leads, Product Owners and QA
• Contributing to CI/CD testing practices
• Ensuring test cases, documentation and automation are kept to a high standard
• Supporting production incidents when required
• (For Seniors) Mentoring junior/intermediate testers and contributing to testing strategy

Key Skills & Experience

• Strong understanding of QA fundamentals, defect management and documentation

Nice to Have

• Performance testing experience (e.g., JMeter)
• Familiarity with TDD/BDD
• Exposure to mobile testing (not essential)

Who This Will Suit

• A Senior Test Engineer who wants to own automation, influence best practices, and work across a modern cloud-native microservices domain
• OR a high-level Intermediate Test Engineer with strong automation skills who is ready to step up
• Someone who enjoys close collaboration in a cross-functional squad
• A tester who is comfortable working in ambiguous or evolving environments and improving testing maturity

Why Join This Team?

• Work on meaningful backend systems within a modern cloud tech stack
• High visibility role within a growing engineering function
• Supportive Engineering Team Lead and collaborative squad
• Real opportunity to uplift automation coverage and leave your mark
• Strong culture of learning, quality and continuous improvement
