About the role

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.
Half is hands-on manual testing of new mobile features before each release cutoff.

Able to move fast without cutting corners, you've worked in environments where release cycles are short and you've figured out how to maintain quality anyway.

Proven mobile QA experience at a product-focused company, not short-term projects or outsourced QA work, somewhere you saw a product evolve through many iterations.
Experience with agentic engineering tools like Claude or Codex to assist in testing workflows, not to replace judgment, but to scale it.
Improve our AI testing harness to reduce the volume of repetitive manual verification, using agentic tools to do the tedious work so you can focus on the hard calls.

(Plus) Experience writing or extending automated tests, whether in a mobile-native framework or otherwise.
(Plus) Background in fintech, crypto, or trading products where accuracy and real-money outcomes raise the stakes on every bug.

Competitive salary & equity
Full Health, Vision, & Dental coverage
Extend automated test coverage across core trading and market resolution flows, identifying gaps and closing them systematically.

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.
