Software Test Engineer

As a Software Test Engineer for Secure Thingz Ltd, you will be expected to work across teams, understanding requirements for new features, identify how these should be tested and produce tests for these. You will have the opportunity to learn from other STZ employees and support the test team in other areas.

Test Debug:

  • To analyse when CI tests are failing, reporting if a genuine bug has been found or a test case error has been detected.
