When an integration breaks, invoices don’t sync, bookings go missing, and customers notice fast.</p><p style="min-height:1.5em">As Senior QA Specialist for the Integrations team, you make sure every release reaches those customers without regressions. You own the team’s test strategy and lead the move from manual release-day testing to an automated, shift-left suite. This is a role with real ownership: you shape how the team thinks about quality, and you grow the practice as our integrations platform grows.</p><p style="min-height:1.5em"></p><h1><strong>What you'll do</strong></h1><ul style="min-height:1.5em"><li><p style="min-height:1.5em">Join refinement with the Integrations team and write Gherkin (Given/When/Then) acceptance specs that developers turn into tests</p></li><li><p style="min-height:1.5em">Test new integrations and API changes end to end: our side, the partner’s side, and everything that can go wrong between them (auth, rate limits, partial syncs, retries, data mapping)</p></li><li><p style="min-height:1.5em">Explore beyond the acceptance criteria to find edge cases, and file clear, reproducible bug reports in Jira</p></li><li><p style="min-height:1.5em">Build and maintain automated tests in TypeScript, with API and contract tests alongside Playwright E2E tests, and review the tests developers write in pull requests</p></li><li><p style="min-height:1.5em">Own the daily automated regression run in GitHub Actions: triage failures the same day and fix flaky tests at the root cause, including ones caused by unreliable third-party sandboxes</p></li><li><p style="min-height:1.5em">Run release-day regression and the OWASP ZAP security scan, and give a clear go / no-go call</p></li><li><p style="min-height:1.5em">Migrate the remaining legacy tests and decide what’s worth automating and what stays manual</p></li><li><p style="min-height:1.5em">Coach developers so they own their tests, and organise QA days with the other product teams</p><p style="min-height:1.5em"></p><div style="min-height:1.2em;margin-top:0px;margin-bott
