Full Job Description
đź“‹ Description
- • As a Senior QA Engineer at Polymarket Inc., you will be responsible for ensuring the quality of our mobile platform, which enables individuals to express views on real-world events by trading on outcomes across politics, economics, sports, culture, and current affairs.
- • You will split your time roughly in half between hands-on manual testing of new mobile features before each release cutoff and improving our AI testing harness to reduce the volume of repetitive manual verification.
- • Your primary goal will be to catch issues that matter to real users before they ship, and to communicate quality status clearly to engineers, product managers, and leadership.
- • You will work directly with mobile engineers to surface bugs early in the development cycle, not just at the end of it.
- • You will be expected to adapt quickly when priorities shift, treating a last-minute scope change as a problem to solve rather than a reason to escalate.
- • You will be responsible for extending automated test coverage across core trading and market resolution flows, identifying gaps and closing them systematically.
- • You will be expected to dig into product behavior with genuine curiosity, asking why things work the way they do and flagging when something feels off even if it technically passes.
- • You will be expected to 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.
🎯 Requirements
- • 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.
- • Comfortable testing on both iOS and Android, with a strong eye for platform-specific behavior and edge cases.
- • 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.
- • Strong communicator who can give a clear, honest quality assessment to a room of engineers and PMs without over-qualifying everything.
- • Genuinely curious about how products work under the hood, not just whether buttons tap correctly but why flows are built the way they are.
🏖️ Benefits
- • Competitive salary & equity
- • Unlimited PTO
- • Full Health, Vision, & Dental coverage
- • 401k match
- • Hardware setup: new MacBook Pro, big display, & accessories
