QA Engineer / Tester — Event Card 72h Performance

You test the live leaderboard end to end as a brand-new visitor would, confirming that cards, baskets and their 72-hour returns render and rank correctly on any screen. You reconcile every ranked return against an independent source of truth and turn each mismatch into a reproducible report and a regression test that keeps it fixed.

What you'll do

• Recompute each card's basket return over the fixed 72h window against outside price data and flag any discrepancy
• Check ranking ties, the window boundaries, and how the board reads on mobile and desktop
• Write every defect as a step-by-step reproduction with expected vs actual numbers
• Convert each confirmed defect into an automated regression test that guards the ranking and the returns

What you bring

• Hands-on experience testing live web apps end to end from a real user's point of view
• Comfort verifying financial and return figures against independent data sources
• Ability to author clear, reproducible defect reports and automated regression tests
• Attention to detail on ranking logic, time windows, and cross-device layout
