Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Mobile Infrastructure Engineer - **Company:** POLYMARKET CLEARING LLC - **Location:** New York, United States - **Salary:** $250,000.0 - $350,000.0 - **Contract:** Permanent contract - **Skills:** Artificial Intelligence, Apple IOS, Application Release Automation, Build Automation, Encodings, Continuous Integration, Programming Tools, Mobile Application Software, Systems Integration, Large Language Models, Sentry, Real Time Data - **Published:** September 5, 2026 - **Apply:** https://startup.jobs/mobile-infrastructure-engineer-polymarket-9925548 ## About the Role * 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 * (Plus) Familiarity with real-time data applications, live market feeds, or trading products on mobile * (Plus) Background in fintech or other data-intensive consumer mobile products ## Description 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., * Own the release tooling across iOS and Android: automated builds, code signing, store submission, phased rollouts, hotfix paths, and post-release health checks after every deployment * Build and maintain CI infrastructure that earns trust: build-time budgets, flaky-test detection and quarantine, merge gates, and device and simulator infrastructure that keeps feedback loops short * Build the quality tooling: regression gates and automated coverage that let the team set and defend crash-free and ANR targets - and go directly into app code to fix crash clusters and harden error paths when the tooling surfaces them * Run the observability stack and alerting that surfaces problems before users feel them * Build AI into the mobile toolchain: create evaluation harnesses for AI-assisted features, embed AI agents into developer workflows, and make AI a first-class part of how the team ships and tests * Measure everything: set budgets, track them over time, and prove improvements with data rather than instinct ## Related Videos - [Xcode development redefAIned](https://www.wearedevelopers.com/videos/100195-xcode-development-redefained) - [Scalable architecture for mobile apps](https://www.wearedevelopers.com/videos/275-scalable-architecture-for-mobile-apps) - [From Doubt to Confidence: How Sentry Uses Verdaccio to Bulletproof SDK Releases](https://www.wearedevelopers.com/videos/739-from-doubt-to-confidence-how-sentry-uses-verdaccio-to-bulletproof-sdk-releases) - [A Brief History of Data Storage](https://www.wearedevelopers.com/videos/974-a-brief-history-of-data-storage) - [Edge AI on iOS: Beyond the Cloud, Designing the Next Generation of Intelligent On-Device Apps](https://www.wearedevelopers.com/videos/100225-edge-ai-on-ios-beyond-the-cloud-designing-the-next-generation-of-intelligent-on-device-apps) - [Harnessing Apple Intelligence: Live Coding with Swift for iOS](https://www.wearedevelopers.com/videos/1515-harnessing-apple-intelligence-live-coding-with-swift-for-ios) ## Related Articles - [A Guide to Choosing the Right Tools for App Developers](https://www.wearedevelopers.com/magazine/391-a-guide-to-choosing-the-right-tools-for-app-developers) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Cross Platform Mobile Development Frameworks to Use in 2025](https://www.wearedevelopers.com/magazine/404-cross-platform-mobile-development-frameworks-to-use-in-2025) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Dev Digest 132 - Binging WADFlix?](https://www.wearedevelopers.com/magazine/473-dev-digest-132-binging-wadflix)
