About this role

Polymarket seeks a Mobile Infrastructure Engineer to own end-to-end mobile infrastructure for a high-traffic prediction market platform, including release pipelines, CI systems, test infrastructure, stability, and observability.

  • Build and maintain CI infrastructure with build-time budgets, flaky-test detection, merge gates, and device/simulator infrastructure to keep feedback loops short
  • Develop quality tooling including regression gates and automated coverage to track crash-free and ANR targets, and fix crash clusters in app code when identified
  • Operate observability stack and alerting systems to surface issues before users encounter them
  • Embed AI into the mobile toolchain by creating evaluation harnesses, integrating AI-assisted features, and building AI agents into developer workflows
  • Establish measurement-driven quality processes with budgets and data-backed improvements across all infrastructure areas

What they're looking for

  • Mobile CI/CD and release automation (fastlane or equivalent)
  • Crash reporting and monitoring (Sentry or similar)
  • Feature flagging systems (LaunchDarkly or similar)
  • iOS and/or Android development and debugging
  • Test infrastructure and device/simulator management
  • AI/LLM integration and evaluation harness design
  • Observability and monitoring systems
  • Data-driven measurement and metrics tracking
