You will partner with developers to ensure adequate feature coverage and proper testing methodology.  You will lead our switch from Cypress to Playwright, as well as kickoff adoption of Detox for testing Playbooks on mobile. You'll teach best practices to minimize flaky tests (and frustrated developers).

  • Deep-diving into hard-to-reproduce issues to narrow reproduction steps
  • Driving improvements to overall QA processes to help reduce manual efforts and increase product quality
