Staff Software Engineer, Mobile QA

As a Staff Software Engineer, Mobile QA at Coinbase, you own the technical strategy for mobile QA infrastructure across the native rewrite of Coinbase's retail mobile app in Swift and Kotlin. You'll set the company's frontend quality bar, translating org-level strategy into the test infrastructure and operational practices that approximately 30 product teams depend upon. The App Infra team is leading this greenfield native rewrite, replacing the existing React Native codebase to deliver a significantly faster experience for millions of customers.

What you'll do

• Own the technical strategy for mobile QA infrastructure across the native rewrite, operating at depth across the team's codebases and designing operational practices that lower maintenance and operational overhead while raising release quality
• Build and scale automated test systems for recurring regression testing, deciding what gets automated versus what stays human across regression, performance validation, and release readiness gating
• Lead the QA readiness workstream for the phased rollout, driving clarity across success metrics, resourcing, and operations
• Guide investment decisions on when to allocate more testing resources and when to pull back as quality gains diminish
• Partner cross-functionally with engineering leadership, product, and design to define SLOs and quality dashboards that provide metric-driven controls for rollout speed decisions
• Shape the QA onboarding playbook for product teams transitioning to native, setting the team's hiring bar for QA contributors and mentoring L3-L5 engineers on test architecture, native debugging, and quality standards

What you bring

• 8+ years of software engineering experience with deep expertise in mobile test infrastructure, including architecting automated regression systems for native iOS and Android at scale
• A track record of defining and delivering test infrastructure strategy that other engineering teams depend on
• Strong proficiency in Swift and Kotlin with the ability to architect test frameworks, debug native app behavior, and enforce compile-time quality constraints, maintaining standards even under pressure to ship
• Experience operating QA processes during large-scale migrations or platform transitions, including managing dual-codebase parity validation, phased rollout quality gates, and leading SEVs and postmortems that improve team practices
• Demonstrated ability to build alignment and secure commitment from cross-team and cross-functional partners on quality standards, testing strategy, and release criteria
• 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 range of $218,025-$286,500 USD, depending on location
• Equity and bonus eligibility
• Benefits including medical, dental, vision, and 401(k)
• Remote-first work with quarterly in-person working sessions called "surges"
