Why we need the role

As a Network on demand Senior QA Engineer you'll have the mission to ensure that the capability we build for our 2 award winning B2B customer-facing Network On Demand applications is of high quality to continue to delight our customers.

The team is small and nimble, and as a result has made amazing progress in the industry, but as we build new features into our applications we want to make sure we don’t accidentally break something.

We work in a business with lots of other applications which are integrated with one-another, so interaction with our peers is key to ensure that our testing is collaborative, effective, and robust.  Sometimes we also have to test the water with new stuff, and so there will be a need to develop spikes/proof-of-concepts to evaluate tools and approaches to ensure the evolution of our testing approach makes best use of new technologies and techniques.
