Description

  • Own and evolve mobile CI systems by designing, maintaining, and improving PR, merge, and release pipelines for iOS and Android.
  • Build and operate CI infrastructure, including runner fleet management, capacity planning, reliability, caching, sharding, and parallelization.
  • Own build system expertise for Gradle, Xcode, and Tuist, improving build performance, determinism, and local-to-CI parity.
  • Define and evolve test architecture for unit, integration, and UI testing, including flaky test detection, quarantine, and remediation.
  • Own developer-facing observability for pre-release workflows, including logging, metrics, and tracing that surface actionable signals.
  • Set technical direction and long-term strategy for mobile CI, build systems, and observability.
  • Mentor other engineers and partner with infrastructure, backend, Testing, and Release teams.
  • Drive improvements in CI runtime, queue time, merge failure rates, and overall developer productivity through measurement and iteration.

Requirements

  • 8+ years of experience in software engineering, CI/CD, or build systems with ownership of production systems.
  • Experience operating CI, build, or test systems across multiple teams or a large codebase.
  • A systems-first mindset with a track record of improving reliability, performance, and developer productivity at scale.
  • Experience supporting high-velocity mobile development teams.
  • Comfort reasoning about distributed systems, shared infrastructure, and capacity-related failure modes.
  • Strong root-cause analysis skills and comfort debugging complex, non-deterministic failures.
  • Excellent communication skills and ability to work effectively across teams and org boundaries.
  • Experience with mobile CI systems at scale, including runner fleets, caching, sharding, and parallel execution.
  • Experience with mobile build systems such as Gradle for Android and/or Xcode/Tuist for iOS.
  • Familiarity with CI observability tools such as metrics, dashboards, and alerting.
  • Scripting and automation experience with tools such as Bash or Python, plus Linux and macOS environments and Git workflows.
  • Familiarity with cloud-based execution environments such as AWS.
  • Mobile development background in iOS, Android, or both (preferred).
  • Deeper hands-on AWS experience beyond CI execution (preferred).
  • Experience mentoring engineers or leading cross-team technical initiatives (preferred).

Benefits

  • Competitive salary and equity packages.
  • Health, dental, and vision insurance.
  • Lunch and wellness benefits.
  • Flexible working hours and work-life balance.
  • An Oura Ring of your own plus employee discounts for friends and family.
