QA Engineer / Tester — Commonstock

You test Commonstock end to end on the live site as a brand-new visitor would, proving that every track record and number shown is built from real fills. You reconcile each figure against an independent source of truth and turn every defect into a reproducible report plus a regression test.

What you'll do

• Walk the full new-user journey on the live site and confirm each record is backed by real fills, not placeholder or simulated data
• Reconcile every displayed portfolio number against an outside source of truth and flag any mismatch
• Write reproducible defect reports with exact steps, expected vs actual, and the discrepancy
• Add a regression test for each confirmed defect so it cannot silently return
• Verify empty, loading, and error states render correctly for a first-time visitor

What you bring

• Rigor in reconciling numbers to a second independent source before trusting them
• Skill at reproducing and isolating defects from a real user's point of view
• Experience writing automated regression tests for web applications
• Comfort testing real-time financial data displayed in a browser
