Mid-level QA / Test Engineer | 12 weeks+ (574)

About the opportunity

We are looking for Mid-level QA / Test Engineers to cover the functional surface of our client's platform and support the lead on high-risk settlement and access-control work.

About our client Our client is preparing two AI-driven platforms for enterprise readiness, with a focus on security, correctness, and financial integrity ahead of a production launch .

What you'll do

• Author and execute functional test cases for core user journeys: account creation, the call / challenge / pool flow, and outcome resolution.

• Test against the SECURITY DEFINER RPC layer rather than direct table access.

• Support the lead on settlement-path and money-movement testing.

• Exercise age-gating and identity-verification flows where testable (subject to Persona credential availability).

• Work with seeded test accounts and data provided by the client, respecting exact handle formatting.

• Log defects with clear repro steps in the shared tracker and re-test after fixes.

What you bring (must-haves)

• Solid QA / test-engineering experience on modern web applications.

• SQL / Postgres proficiency for validating data and results.

• Working knowledge of Next.js or comparable JS frameworks and API/RPC testing.

• Careful, detail-exact test execution and reproducible defect reporting in clear written English.

Bonus points for (nice-to-haves)

• Exposure to payments, wallet, or transaction testing.

• Familiarity with Supabase / Vercel.

• Interest in real-money-platform testing and a path toward settlement work.
