Role Overview
As a Senior Software Tester, you will work on the continued build of our MDA platform, which ingests large volumes of streaming data from satellite, terrestrial, and other sensor sources. You will play a key role in validating the behaviour of a distributed, event‑driven system operating on real‑time maritime data, performing both automation and manual testing. The role is hybrid, based from our Cardiff office, with a requirement to attend the office one day per week as needed.
How We Work
Tickets move across the Jira board through the delivery workflow. Tickets reaching the Test stage are assigned to a tester, who validates functionality using a mix of automated and manual testing approaches.
Every six weeks we conduct a dedicated two‑week QA phase where the focus shifts to release‑wide regression testing. Both manual and automated test suites are executed to validate the full platform.
