Job Description
Senior QA Automation Engineer (TypeScript)Location: San Diego (San Marcos) and/or Vancouver (Canada).About the RoleWe're looking for a Senior QA Automation Engineer who doesn't just run tests — you build the testing infrastructure. You'll own quality end-to-end across Web, Mobile (iOS and Android), and Desktop (Windows and Mac), designing automation frameworks from the ground up and driving a Shift-Left quality strategy that catches issues before they reach staging.This is a high-impact role where you'll shape how we think about quality, mentor engineers, and have direct influence on the products our users experience daily.What You'll Do
- Build automation frameworks from scratch in TypeScript using Playwright (Web) and Appium (Mobile), with the ability to integrate UI, API, and database validation into cohesive end-to-end test suites
- Own the QA strategy — design test plans, establish coverage standards, and drive Shift-Left testing practices that reduce defects before they hit staging
- Write and maintain automation scripts in TypeScript — this is your primary language, not a nice-to-have
- Test across platforms — validate application behavior across iOS, Android, Windows, and macOS, including device-level testing, log analysis, and environment-specific validation
- Debug at every layer — use tools like RestAssured, Charles Proxy, ADB, Android Studio, Xcode diagnostics, and Web Inspector to perform cross-layer root cause analysis
- Drive performance testing using JMeter for high-traffic, real-world scenarios
- Validate data integrity using SQL across Oracle, MySQL, and PostgreSQL
- Mentor and elevate — coach team members on test design, automation patterns, defect lifecycle, and continuous quality practices
- Manage test operations — build traceability and reporting workflows using tools like TestRail, Jira, or equivalent
- Collaborate cross-functionally with developers, product, and design teams to clarify requirements, identify gaps, and ensure comprehensive test coverage
- 5+ years in QA automation with a focus on building frameworks, not just writing scripts within existing ones
- TypeScript expertise — you've built production automation frameworks in TypeScript, not just maintained them
- Playwright experience — hands-on framework design and implementation for modern browser automation
- Mobile testing proficiency — Appium or equivalent across iOS and Android, including real device testing and debugging
- Cross-platform testing experience — Web, iOS, Android, Windows, and Mac
- Strong SQL skills for backend data validation
- API testing experience with RestAssured, Postman, or similar tools
- CI/CD integration — experience embedding automated test suites into Jenkins or equivalent pipelines
- Performance testing experience with JMeter or LoadRunner
- Shift-Left mindset — you proactively identify requirement gaps and quality risks before code is written
- Leadership ability — you've mentored QA engineers and driven quality culture within a team
- Experience building QA organizations or processes from zero
- BDD experience with Cucumber/Gherkin
- Familiarity with AI-assisted QA workflows
- Background in gaming, entertainment, or high-engagement consumer products
- Java automation experience alongside TypeScript
