Lead Test Engineer

Remote

Permanent, full time

We are seeking an experienced Lead Test Engineer to take ownership of our automated testing capability and help drive the next phase of our quality journey. We already have a strong foundation, including a Playwright based automation framework and a substantial automated UI test pack. This role will focus on expanding and evolving that capability: increasing coverage, improving reliability, integrating automation into delivery workflows, and shaping how we test new functionality and new components.

You will work closely with engineers and QA colleagues, and provide guidance and practical support to our manual QA testers as they develop their own automation skills. The ideal candidate is hands‑on, pragmatic, and self‑directed, someone who can identify what needs doing, propose sensible improvements, and deliver at pace with minimal direction. You will report directly to the Chief Technology Officer and provide regular updates to our IT Delivery Manager.

• Own and evolve the Playwright UI automation suite, expanding coverage across critical user journeys and high‑risk areas.
• Design, develop, and maintain robust, scalable Playwright based automated tests (.NET preferred with BDD knowledge using Reqn Roll), following best practices for reliability and maintainability.
• Improve automation quality (stability, speed, diagnostics), including reducing flaky tests and strengthening reporting/observability of failures.
• Define and drive the test approach for new functionality and new components, including services and integrations (e.g., Azure Functions, APIs, background processes), not just UI.
• Collaborate with developers and QA to ensure testability is built into delivery (clear acceptance criteria, suitable test hooks, pragmatic test strategies).
• Integrate and optimise automated testing within CI/CD (e.g., Azure Dev Ops), including gating, smoke/regression strategies, and environment‑aware execution.
• Assist in defect triage and support timely resolution by providing clear evidence, repro steps, and technical insight into root cause patterns.
• Mentor and support manual QA testers as they progress towards automation, including pairing, coaching, and creating simple patterns they can follow safely.
• Create and maintain clear documentation, standards, and “how we test here” guidance that enables consistent delivery across the team.
• Proactively identify gaps and propose improvements across the wider quality approach (e.g., API automation, contract testing, performance checks, data/test environment strategy).

• Proven experience building and maintaining test automation in modern software delivery environments, with a bias for pragmatic outcomes over theory.
• Solid understanding of testing strategy and how to balance UI, API/service, and integration testing to achieve confidence efficiently.
• Experience working with CI/CD pipelines (ideally Azure Dev Ops), including test execution, reporting, and quality gates.
• Comfortable testing systems built on a .NET backend and JavaScript‑based frontend; able to work effectively with engineers across both stacks.
• Experience testing APIs and service components (including…
