About The Role

We’re seeking a QA Engineer to join our team as a technical gatekeeper for quality. At Arena Club, QA is deeply integrated into the development lifecycle: every developer ticket requires manual verification and approval from our QA team before release.

This role is ideal for someone who thrives in a high-automation environment (~90% coverage) but understands the critical value of manual exploratory testing for new features. You will be a Playwright and TypeScript specialist, a SQL power-user for technical support, and a performance advocate ensuring our mobile experience is world-class across all devices.

What You Will Do

• Ticket Approval & Verification: Act as the final checkpoint for every developer ticket, performing manual verification and release testing to ensure all regression and automation tests pass.
• Advance Automation: Build and maintain end-to-end (E2E) test suites using Playwright and TypeScript, focusing on new feature development and closing existing automation gaps.
• Technical Support: Leverage SQL to perform data validation, investigate complex technical support escalations, and troubleshoot backend workflows.
• Comprehensive Testing: Own the execution of functional, non-functional, regression, and smoke testing, with a specific focus on performance testing across different mobile devices.
• Collaboration: Partner with Engineers to define test coverage while developers manage unit/integration tests, ensuring a robust E2E testing layer.
• Defect Management: Log, track, and retest defects with high-precision documentation and reproducible steps.

Qualifications

• 4+ years of QA Engineering experience in a fast-paced software environment
• Strong hands-on experience writing and maintaining automation frameworks using Playwright and TypeScript
• Solid SQL skills (including joins and complex queries) to assist with technical support and data integrity checks
• Prior experience in a technical customer support role or a high-collaboration engineering environment
• A disciplined approach to manual testing for critical flows and a commitment to high-quality documentation
• Comfortable working as a contractor in a global, distributed team

Preferred Qualifications

• Specific experience performing automation and performance testing across a variety of mobile devices (real devices, not emulators) using Appium
