Job description

Senior QA Automation Engineer (TypeScript)

Location: Boca Raton, FL — Onsite (W2)

About the Role

We'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

What You Bring

• 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

Bonus Points

• 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
