## About the role

Polymarket is looking for a Mobile Infrastructure Engineer to own mobile infrastructure end-to-end: the release pipeline, CI, test infrastructure, stability, and observability that let a small mobile platform team ship a high-traffic trading product quickly and safely. You'll also help build our AI layer — the harnesses, evaluations, and developer tooling that make AI a first-class part of how we build and ship mobile software.

## What they're looking for

- Broad mobile infrastructure experience at consumer scale, including CI/CD, release automation, test infrastructure, and stability work on iOS, Android, or both
- Hands-on experience with mobile release tooling: crash reporting and monitoring with Sentry or similar, feature flagging with LaunchDarkly or similar, and release automation with fastlane or an equivalent
- Practical experience applying AI to engineering work: building evaluation harnesses, integrating LLM-powered features, or embedding AI agents into developer workflows
- Measurement-driven approach to quality — you instrument, set budgets, and prove improvements rather than operating on gut feel
- Willingness to go into app code when the tooling surfaces problems — you can fix crash clusters and harden error paths yourself while your core ownership stays the tooling and infrastructure around the app
- Generalist temperament: comfortable owning the tooling for release, CI, quality, observability, and AI at the same time on a small team, and able to drive each area without heavy oversight
