QA Engineer / Tester — Gem Screener

You test Gem Screener end to end on the live site exactly as a brand-new visitor would, then reconcile every revenue, market-cap and ranking figure it shows against an independent source of truth. Each defect you find becomes a reproducible report and a regression test that keeps it from returning.

💰 Salary: $85,000 – $135,000 USD / year · Remote OK

What you'll do

• Walk the full user path on the live site: browse the ranking, switch sector boards, open a token detail panel
• Reconcile every displayed revenue, market cap and revenue-to-cap rank against an outside reference and flag mismatches
• Verify real-time data updates, sort order, sector filtering and detail-panel accuracy across desktop and mobile
• Turn each defect into a step-by-step reproducible report with expected versus actual values
• Add a regression test for every confirmed bug so the same defect cannot silently return

What you bring

• Rigor reconciling numbers against independent sources and refusing to accept a figure you cannot verify
• Skill writing precise, reproducible bug reports and automated regression tests
• Comfort testing live web apps as a real first-time user, including empty and error states
• Attention to ranking logic, sorting and filtering correctness under real-time updates
