Senior AI DevOps Engineer

About the role

The mobile team ships the Roku Remote, Smart Home, and Howdy apps on iOS and Android. You own the CI/CD pipeline and QA automation infrastructure for the mobile engineering team.

Responsibilities

• Design and maintain CI/CD pipelines for iOS and Android on GitLab
• Architect pipeline stages for fail-fast execution: cheapest checks first (lint, compile, static analysis), expensive checks last (device farm tests)
• Build smart test routing: analyze MR diffs to determine which tests need physical devices and which can run on emulators, so 80% of MRs never touch the device farm
• Build flaky test detection and quarantine systems. Classify failures as infrastructure-caused vs. code-caused so engineers trust the signal
• Automate release mechanics: code signing, versioning, TestFlight/Play Console uploads, dSYM and mapping file management. The goal is zero manual steps between merge and app store submission
• Build the device reservation and orchestration system that assigns devices to CI jobs, prevents contention, and maximizes utilization without manual scheduling
• Design self-healing automation: health checks detect unresponsive devices, trigger remote recovery via API, and re-register them no human intervention required
• Define the device compatibility matrix which firmware/model combinations require real hardware, and which can run on emulators
• Implement priority-based test routing: device-touching MRs get farm time, UI-only MRs never queue for a device
• Use AI to identify failure patterns, predict infrastructure issues, and continuously optimize pipeline performance

Requirements

• 5+ years' operating CI/CD infrastructure at scale, preferably GitLab CI
• Ability to travel up to 20%
• Strong scripting (Python, Bash) and ability to build internal tooling
• Experience with infrastructure-as-code (Terraform, Ansible, or equivalent) for managing cloud and on-premises infrastructure
• Experience with mobile test automation frameworks (XCUITest, Espresso, Appium)
• Experience scaling CI for high-volume, automated code generation (agentic engineering, bot-authored MRs)

Qualifications

• Deep understanding of mobile build systems (Xcode/xcodebuild, Gradle) and mobile-specific CI challenges (code signing, provisioning, multi-platform builds)
• Advanced proficiency with AI-assisted development (Copilot, Claude Code, Cursor, or equivalent)
• Experience designing autonomous, self-healing systems that detect, diagnose, and recover from failures without human intervention
• AI-first problem solving where your instinct is to automate with AI before adding manual process or headcount
• Data-driven decision making. Measure failure rates, waste rates, device utilization, and pipeline duration and use those numbers to prioritize your work
