Mid-level QA / Test Engineer

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, and log defects with clear repro steps in the shared tracker.

What you bring:

• 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.

Perks & benefits:

• Equipment provided — none of that "bring your own device" stuff here. Full back-office support — Legal, Accounting, HR Business Partner, and Delivery team.
• Career and cultural mentoring — how to show up, stand out, and navigate US work culture. Free English lessons with a native speaker.
• Referral bonus — recommend Ubi to your tech friends and get paid for it. Florianópolis HQ always open — 100% remote, but the office is there whenever you want it.
