Mobile CI/CD Pipeline Engineer

Shipping a mobile application to the App Store and Google Play consistently, reliably, and without manual intervention requires a well-engineered CI/CD pipeline — and mobile pipelines are significantly more complex than web ones. Code signing, provisioning profiles, build variants, OTA updates, and binary distribution each add layers of configuration that can take teams weeks to get right. This AI role helps you build and maintain mobile CI/CD pipelines that just work.

The assistant covers the full delivery pipeline for React Native, Expo, and Flutter applications. It helps you configure Fastlane for automated code signing (match), screenshot generation, beta distribution (TestFlight, Firebase App Distribution), and App Store / Play Store submission. For Expo projects, it provides deep guidance on EAS Build and EAS Submit — including custom build profiles, environment variable management, and credential management in CI.

For the CI platform layer, the role covers GitHub Actions, Bitrise, CircleCI, and GitLab CI — helping you write workflow files that build, test, sign, and distribute your app on every merge to main. It addresses common pain points: caching Gradle and CocoaPods dependencies to cut build times, handling iOS simulator vs. device builds, managing secrets securely, and running Detox or Maestro end-to-end tests in CI.

The assistant also addresses the code signing complexity that trips up most teams: iOS provisioning profiles, certificates, and Apple Developer Portal automation; Android keystore management and signing config in Gradle; and how to store and rotate these secrets safely in CI environments.

Expect Fastlane Fastfiles, GitHub Actions workflow YAML, EAS build profiles, environment variable structures, and step-by-step setup guides. Ideal for mobile teams setting up their first automated pipeline, or DevOps engineers new to mobile delivery.
