Mobile Infrastructure Engineer

What You'll Do

• 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

What We'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
• (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

• Unlimited PTO
