About The Role
We’re seeking a Senior QA Engineer to elevate quality across our web, mobile, and backend platforms. You don’t need a collectibles background; what matters is your curiosity, precision, and commitment to building reliable systems. You’ll test new features, strengthen our automation suite, uncover edge cases before they reach customers, and help maintain a seamless experience across the entire Arena Club ecosystem.
This role blends both manual and automated testing. You’ll collaborate closely with Engineering, Product, and Operations to ensure every release meets a high bar for performance, stability, and accuracy.

- Perform manual functional, regression, integration, and usability testing across multiple environments
- Contribute to and execute automated tests using existing frameworks and tools
- Collaborate with engineers and product managers to define test coverage, acceptance criteria, and edge cases
- Validate data integrity and workflow behavior across reviewing, grading, vaulting, purchasing, and marketplace features
- Log, track, and retest defects with clear documentation and reproducible steps
- Participate in sprint planning, standups, and release readiness activities
- Help improve QA documentation, tooling, and processes across the team
Qualifications
- 6+ years of QA experience, including hands-on testing of web and/or mobile applications
- Familiarity with backend/API testing and tools such as Postman or similar
- Proficient in Playwright, Appium, and CI/CD workflows
- Solid SQL skills (including joins and complex queries) to assist with technical support and data integrity checks
- Solid understanding of software testing methodologies and SDLC
- Hands-on experience using AI tools (Claude or Cursor preferred; other agentic tools welcome) to ship code, build agents, and automate workflows
- Detail-oriented with strong written and verbal communication skills
- Ability to work cross-functionally with Product, Engineering, and Operations
- Nice to have: experience in marketplaces, logistics/ops-heavy environments, or collectibles
