# QA Engineer / Tester — NinjaScript

QA Engineer / Tester · NinjaScript · Remote · Job ID JOB-940

You test NinjaScript end to end on the live EventTrader site exactly as a brand-new user would, starting from an anonymous visit and a fresh key-issued signup. You reconcile every number the app shows against an outside source of truth and turn each defect into a reproducible report plus a regression test.

⭐ Bonus points for any apps built on the platform using "Build it Better": https://cymetica.com/build-it-better

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

## What you'll do

- Walk the public site and documented API as a first-time stranger before assuming anything works
- Reconcile each user-facing figure against an external reference, not just internal consistency
- Sanity-check every displayed value and treat a violated expectation as a defect
- File each issue with exact repro steps and cover it with a lasting regression test
- Withhold a pass when results cannot be verified rather than declaring green

## What you bring

- Rigorous black-box testing instinct and comfort verifying live web and documented APIs
- Habit of validating numbers against independent outside sources
- Clear, reproducible defect reporting and regression test authoring
- Understanding of how traders read strategy data enough to spot wrong figures
