Senior QA Automation Engineer (Playwright) London /WFH to £90k

Do you have expertise in test automation?

You could be progressing your career in a hands-on Senior QA Automation Engineer role at a scaling Fintech who have built a highly complex, real-time energy trading platform to revolutionise energy buying for large industrial and commercial users.

This is a senior, highly autonomous QA role with a strong focus on test automation, end-to-end integration and data flows. The core platform uses AI to process unstructured data from multiple document types, extract information and move it through a complex network of internal systems. You'll be responsible for ensuring these integrations and data journeys work accurately, reliably and at scale.

As a Senior QA Automation Engineer rather than focusing purely on testing individual applications, you'll take ownership of testing the connections between systems, with internal integrations predominantly API led and built on a modern data platform.

The role is also highly business facing, you'll work closely with stakeholders to understand requirements, define acceptance criteria, support user acceptance testing and ensure the platform meets real operational needs.

Location / WFH:

You'll join the team in the London office three days a week with flexibility to work from home the other two days.
