The Opportunity

We’re hiring a Senior Mobile Release Engineer to own the end-to-end mobile build & release pipeline for iOS and Android. You’ll design, operate, and scale the CI/CD systems that produce our apps; keep code signing healthy; and automate delivery to TestFlight and Play Console. Your north star: fast, reliable, observable releases that mobile engineers trust.

You’ll partner closely with mobile engineers and platform teams to standardize workflows across Kotlin Multiplatform, React Native, and native codebases.

Responsibilities

• CI/CD Ownership: Architect, maintain, and harden mobile pipelines (primarily GitHub Actions; similar tools a plus) for build, test, sign, and release.

• Build Farm & Runners: Operate macOS build hosts and Linux runners (autoscaling, capacity, caching, images, lifecycle). Keep Xcode/SDK toolchains in sync and reproducible.

• Release Engineering: Define the release train (branching, semantic versioning, tagging, changelogs), manage TestFlight / Play promotion (alpha → beta → prod), phased rollouts, and rollbacks.

• Code Signing at Scale: Own certs/profiles/keystores rotation, secure storage, and automated provisioning; eliminate manual steps and flaky signing.

• Tooling & Automation: Build and evolve Fastlane/Gradle/Xcodebuild scripts, artifact storage (S3/Artifactory), symbol uploads (dSYMs/ProGuard), and cache strategies (Gradle remote cache, derived data).

• Observability: Instrument pipelines with metrics and alerts (queue time, success rate, median/p95 duration, cache hit rate). Publish dashboards and SLOs for builds and releases.

• Performance & Reliability: Drive down build/test time; de-flake critical jobs; enforce concurrency limits and test sharding; keep green builds predictable.

• Security & Compliance: Implement OIDC-based secrets, least-privilege runners, SBOM/attestations for mobile artifacts, and audit trails for store submissions.

• Developer Experience: Create templates, reusable actions, and docs; make local setup fast and consistent. Unblock engineers quickly with crisp runbooks.

• Governance: Gate production promotion on quality signals (crash/ANR thresholds, perf checks, test coverage) and ensure release checklists are followed.

Qualifications

• Deep hands-on with Xcodebuild / Xcode Cloud concepts, Fastlane, Gradle/AGP; comfort across KMP, React Native, and native projects.

• 5+ years in Build/Release/DevOps roles, 3+ yrs focused on mobile CI/CD.

• Proven experience running GitHub Actions (or CircleCI/Jenkins) for mobile at scale: reusable workflows, composite actions, caches, matrices.

• Operated macOS build hosts (EC2 Mac/bare-metal) and Linux runners on cloud—AMI/image mgmt, containers & K8s, patching, autoscaling, concurrency & cost control.

• Strong code signing chops: certificates, provisioning profiles, keychains/keystores, App Store Connect & Google Play Developer APIs.

• IaC & scripting: Terraform (or similar), plus Bash/Python to automate pipelines and infra.

• Solid understanding of branching models, semantic versioning, and artifact/version governance.

• Excellent debugging and cross-team communication; bias toward automation and measurable outcomes.

Nice to have:

• Gradle, or remote build cache experience.

• Firebase App Distribution, Crashlytics/Sentry symbolication automation.

• GitOps patterns and secrets management in CI (e.g., OIDC to cloud KMS).

• Mobile perf gates (TTI/ANR/crash) as release criteria; store metadata automation

What success looks like (90-180 days)

• Build time ↓ 30–50% on core apps; p95 pipeline duration and success rate visible on dashboards.

• Zero flaky signing: automated cert/profile/keystore management with rotation policy.

• Green, predictable releases: weekly/bi-weekly trains with phased rollouts and one-click rollback.

• Observability in place: alerts for queue spikes, cache misses, failures; clear runbooks.

• Developer friction ↓: standardized templates/actions; new apps onboarded to CI in <1 day.
