Purpose of the job

We’re looking for a SDET who’s passionate about quality; not just as a phase, but as a core part of how great software gets built.

This role requires strong software development skills, deep understanding of distributed systems, and the ability to influence quality across the entire software development lifecycle (SDLC).

You’ll be embedded in a collaborative environment where software is shipped fast, iteratively, and often. Your work will focus on making sure things don’t just work but work well together. You’ll bring clarity, structure and confidence to the way we test by balancing automation with human insight and keeping the end-user in mind.

You would drive the automated testing efforts covering contract testing, smoke testing, regression testing, cross-device compatibility testing, end-to-end testing ensuring that we deliver quality and performance of mobile applications through manual and automated testing. You’ll bring your considerable knowledge of test automation to help us build new products that are reliable, secure, performant, and resilient.

If you’re curious, love asking the awkward questions, and want to support software engineers build and iterate quickly, you’ll thrive here.
