ABOUT ARENA CLUB

Arena Club is redefining the sports cards and memorabilia landscape through the

industry’s first digital card show. Co-founded by 5x World Series Champion Derek

Jeter and serial entrepreneur Brian Lee, Arena Club delivers a fully digital,

trust-driven marketplace built for collectors. Our platform integrates grading

and authentication, vaulting, and digital pack experiences, empowering users to

buy, sell, and showcase collections in personalized online showrooms from

anywhere in the world.

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.

WHAT YOU WILL DO

* Design, maintain, and execute test plans and test cases for web, mobile, and

backend services

* 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

THE ARENA CLUB STANDARD

Life at Arena Club isn’t designed for comfort. We’re building products and

experiences the collectibles industry has never seen, and that requires urgency,

resilience, and an obsession with excellence. This is where talent comes to

prove itself.

From day one, you own outcomes. You’re trusted to deliver, expected to raise the

bar, and encouraged to innovate beyond what’s been done before. Predictability

isn’t part of the deal. Impact is.

If you’re ambitious, competitive, and ready to grow faster than you thought

possible, step into the arena. This is where you’ll be challenged, supported,

and rewarded in ways few environments can match.

The base salary range listed is a guideline. Actual compensation is determined

based on skills, experience, and the impact you bring. Total compensation

includes base salary, bonus, and equity.
