What you’ll do

We’re looking for a Release Engineer to support and streamline the delivery of our Mobile (iOS & Android) and Extension (browser-based) applications. This is not a traditional DevOps position — it’s a hands-on, team-facing role focused on ensuring build quality, release consistency, and delivery velocity across platforms.

You’ll work closely with engineers, QA, and product managers to support day-to-day release needs, review cherry-picks, manage builds, validate artifacts, and continuously improve our tooling and processes.

Responsibilities:

• Support engineering teams with day-to-day release tasks, including cherry-pick reviews, build validations, and release coordination
• Own and maintain CI/CD pipelines using Bitrise, GitHub Actions, GitHub Runners, Advanced GH Workflows and CircleCI
• Automate and improve build/test/release workflows via scripting (Bash, TypeScript/JavaScript, etc.)
• Monitor build health, troubleshoot issues, and proactively resolve blockers
• Ensure proper versioning, tagging, and signing of builds for mobile and browser extension platforms
• Submit and track releases on App Store, Play Store, and extension stores (Chrome, Firefox, Edge)
• Partner with QA to integrate and validate unit, UI, and E2E tests in release workflows
• Maintain clear documentation and checklists for release processes
• Coordinate feature flag rollouts using LaunchDarkly in collaboration with engineering and product

What we're looking for:

• 3+ years of experience in release engineering, CI/CD, or build/release coordination (not just infrastructure)
• Experience supporting cross-functional teams and reviewing/cherry-picking production code branches
• Deep knowledge of CI/CD tools: Bitrise, GitHub Actions, CircleCI, GitHub Runners
• Strong scripting ability, GH Actions, YML-based systems
• Git workflows (trunk-based, Git Flow) and semantic versioning
• Excellent communication skills and the ability to support fast-moving teams

Would be great if you brought this to the role

• Experience with LaunchDarkly or other feature flag systems
• Understanding of staged rollouts, crash monitoring, and store compliance processes
• Familiarity with extension-specific policies (e.g., CSP, permission management)
• iOS builds & release (Fastlane, Xcode, TestFlight, App Store Connect)
• Android builds & release (Gradle, Play Console)
• Browser extensions (manifest v2/v3, WebExtension APIs, Chrome/Firefox/Edge stores)
• Contributions to release tools, automation frameworks, or documentation in open source or prior roles

Don't meet all the requirements? Don't sweat it. We’re passionate about building a diverse team of humans and as such, if you think you've got what it takes for our chaotic-but-fun, remote-friendly, start-up environment—apply anyway, detailing your relevant transferable skills in your cover letter. While we have a pretty good idea of what we need, we're ready for you to challenge our thinking on who needs to be in this role.
