We are professionals with purpose, beating cancer every day. But we need to go much further and much faster. That’s why we’re looking for someone talented, someone who wants to develop their skills, someone like you.

Cancer Research UK has an ambitious Engineering Strategy and modern Tech Stack with a complex hybrid (on-premise & multi-cloud) infrastructure underpinning an extensive technical estate.

As a Senior QA Engineer, you will be part of our Fundraising & Trading portfolio rotating across a range of change initiatives, products, and in-house solutions that helped raise £597m towards Cancer Research UK's life-saving work (e.g., our events management product which enables mass events such as Race for Life, London Marathon, SU2C, Shine; our Online Fundraising Web Application, our Ecommerce platforms, and many more). You will be involved in the whole Software Development Lifecycle process from initial planning to execution and monitoring. You’ll partner closely with Product teams and end-users to ensure systems are operating effectively and safely by designing, developing, and maintaining test automation frameworks. You’ll also support the QA team in moving away from manual testing to automated processes whilst supporting the development of our QA Engineers.
