Job summary

Rentman is seeking a Senior QA Specialist for the Integrations team to ensure releases reach customers with no regressions. You will own test strategy, move from manual release testing to automated, shift-left testing, and grow QA practices as our integrations platform scales.

You’ll write Gherkin specs, test REST APIs and integrations end-to-end, and drive automated tests in TypeScript with Playwright. You’ll advocate quality across the team and mentor developers in testing best practices.

Qualifications

• 5+ years in QA on web applications.
• Hands-on experience testing REST APIs and integrations with external systems (Postman, Playwright API testing or similar), including authentication flows like OAuth and webhooks
• At least 2 years writing and maintaining test automation in code (Playwright, Cypress or Selenium, ideally TypeScript/JavaScript)
• Strong exploratory testing skills, with bug reports developers can act on without follow-up questions
• You’ve defined a test strategy (what to automate, what to test manually, coverage), not only executed test cases
• Experience running automated tests in CI (GitHub Actions or similar)
• You get developers to adopt new habits through pairing, good examples and clear specs, not by policing

Responsibilities

• Write Gherkin acceptance specs with Integrations team.
• Test new integrations and API changes end to end including auth and retries.
• Explore beyond acceptance criteria to find edge cases and file reproducible bug reports in Jira.
• Build and maintain automated tests in TypeScript with API and contract tests alongside Playwright E2E tests.
• Own the daily automated regression run in GitHub Actions; triage failures and fix flaky tests at the root cause.
• Run release-day regression and the OWASP ZAP security scan; give a go/no-go.
• Migrate legacy tests and decide what’s worth automating.
• Coach developers so they own their tests and organize QA days.
