Senior QA Engineer (Contractor)

As a Senior QA Engineer at Trust Wallet, you own and evolve the automation ecosystem across Android and iOS. You'll work within a modern TypeScript-first monorepo, building a unified test framework from the ground up and embedding quality gates deep into trunk-based CI/CD pipelines. This role is highly technical — you'll design frameworks, own CI/CD reliability, and work closely with mobile and platform engineers to shift quality left.

What you'll do

• Own the automation testing platform for mobile (iOS and Android)
• Build and maintain the unified QE SDK using WebdriverIO and TypeScript
• Integrate testing into CI/CD using GitHub Actions for smoke, regression, and release-gate pipelines
• Implement best practices for test parallelisation, tagging, stability, and flake detection with automatic quarantine
• Improve test observability through dashboards, trend tracking, and artefact management for test runs
• Manage device farm coverage strategy via cloud device providers, including device matrix, session configuration, and cost efficiency
• Contribute to QE SDK onboarding via Claude Code skills and contribution guidelines
• Mentor engineers on testing techniques, CI/CD integration, and reliability practices

What you bring

• 3+ years in QA automation or SDET roles with end-to-end framework ownership
• Strong hands-on experience with TypeScript as a primary language
• Experience with mobile automation for iOS and Android
• Proven ability to build and maintain CI/CD pipelines in GitHub Actions
• Solid understanding of flake root causes, including retry strategies, quarantine, and stability metrics
• Familiarity with Web3 or blockchain concepts at an engineering level, including wallets, transactions, signing, and networks
• Excellent collaboration and async communication skills in a remote-first team

Nice to have

• Experience with WebdriverIO and/or Appium
• Experience integrating feature flag systems into automated test sessions
• Prior work on quality dashboards or data-driven test analytics
• Exposure to containerised or cloud-based test infrastructure
• Experience with performance or visual regression testing

What we offer

• Fully remote, global role with flexible working hours
• Competitive salary and benefits
• Learning and career development opportunities
