QA Engineer / Tester — Alpha Vantage

You test Alpha Vantage on the live EventTrader site exactly as a brand-new user would, walking every screen and request path the moment you arrive. You reconcile every figure the app shows against an independent outside source, and you turn each mismatch or defect into a step-by-step reproducible report plus a regression test that keeps it from returning.

⭐ 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

• Exercise the full app end to end on the live site as a first-time user, from first load through repeated authenticated requests up to the published 100/min limit
• Reconcile every number the app displays against an outside source of truth and record any discrepancy
• Confirm the app enforces its stated request limits accurately and behaves correctly at and beyond them
• Write each defect as a reproducible report with exact steps, expected vs. actual, and evidence
• Convert every confirmed defect into an automated regression test so it cannot silently reappear

What you bring

• Rigorous manual and exploratory testing skill on live web apps from a real user's perspective
• Habit of verifying displayed data against independent references rather than trusting the screen
• Ability to write precise, reproducible defect reports and matching automated regression tests
• Comfort testing rate-limited request behavior and authenticated flows
