QA Engineer / Tester — yfinance

You test EventTrader's documented, keyed market and signal API on the live site exactly as a brand-new user would, from first request to real data returned. You reconcile every number the app shows against an independent outside source of truth and turn each defect into a reproducible report plus a lasting regression test.

⭐ Bonus points for any apps built on the platform using "Build it Better"

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

What you'll do

• Walk the full new-user path on the live site: read the docs, get a key, make first market and signal calls, confirm stable documented responses
• Reconcile every price, quote and signal the app returns against an independent outside reference and flag any mismatch
• Test rate-limit behavior and stability so results stay dependable where the old Yahoo-based flow broke
• Write each defect as a step-by-step reproducible report with exact request, expected vs actual, and severity
• Convert every confirmed defect into an automated regression test that guards the fix going forward

What you bring

• Hands-on API and web QA experience, including reading docs and exercising keyed endpoints end to end
• Rigor in reconciling financial numbers against a second source and spotting subtle discrepancies
• Ability to write clear reproducible bug reports and durable automated regression tests
• Understanding of market data concepts: prices, quotes, symbols and derived signals
