Senior QA Engineer, Platform

About the Role

Our Mobile Platform Team ships fast. We're iterating constantly on a product that millions of people use to make real-money predictions on real-world events, and quality is not optional. This role exists because we need someone who can hold the line on quality without slowing us down, someone who sees every release as a responsibility, not a formality.

You'll split your time roughly in half. Half is hands-on manual testing of new mobile features before each release cutoff. The other half is making that manual work increasingly unnecessary by improving our AI testing harness and extending automated coverage across our core flows. This isn't a role where you're just running scripts someone else wrote or checking boxes on a test plan. You'll have real ownership over how quality gets defined and verified on this team.

The right person for this role has worked at a product company where the app was always evolving and where "we'll fix it later" wasn't an option. You've seen what it looks like when quality slips at scale, and you don't want to be the reason it happens here.

What You'll Do

• Manually test new mobile features end-to-end before each release cutoff, catching issues that matter to real users before they ship.

• Sign off on releases and communicate quality status clearly to engineers, product managers, and leadership, no ambiguity, no hedging.
