Senior Software Engineer, Mobile QA

As a Senior Software Engineer, Mobile QA at Coinbase, you own the test infrastructure and quality processes for the greenfield native rewrite of Coinbase's retail mobile app in Swift and Kotlin. You'll replace the existing React Native codebase, building automated regression frameworks integrated into the AI-assisted code generation loop so defects are caught at commit time, not after release.

What you'll do

• Own the design and implementation of automated regression test suites for native iOS and Android builds, setting the project-level quality bar through code reviews, test standards, and trade-off analysis that teammates and partners trust
• Build test infrastructure integrated into the AI code generation cycle, enforcing automated test and performance verification at commit time and defaulting to automation where manual steps currently slow the team
• Partner with mobile engineers to close coverage gaps, eliminate flaky tests, and fix the slow debugging workflows the team has learned to tolerate
• Architect the QA strategy for the greenfield rollout, solving high-complexity problems around catching regressions while supporting urgent last-minute changes from product teams
• Establish quality dashboards and SLOs that give the team real-time visibility into app stability, dropped frames, stall counts, and cold start times, turning release-by-release firefighting into durable, ever-increasing quality

What you bring

• 5+ years of software engineering experience with a focus on mobile test automation, including hands-on experience with XCTest, Espresso, or equivalent native testing frameworks for iOS and Android
• A proven track record building automated regression infrastructure integrated into CI/CD pipelines (Buildkite, CircleCI, or similar), with measurable impact on release quality and cycle time
• Proficiency in Swift and Kotlin sufficient to read, debug, and write test code against native mobile codebases, with demonstrated ability to architect robust technical solutions through trade-off analysis
• The ability to use generative AI responsibly, maintaining human oversight to deliver business-ready outputs and measurable gains in workflow efficiency, cost, and quality

What we offer

• Annual base salary of $186,065-$218,900 USD, depending on location
• Equity and bonus eligibility
• Benefits including medical, dental, vision, and 401(k)
• Quarterly in-person working sessions called "surges"
• Remote-first work environment
