About us

Rentman is a B2B SaaS scale-up building a smart, powerful operations management platform to support event and media production teams. Our users plan everything from small shoots to massive festivals in 70+ countries, and they all rely on Rentman to keep their gear, people, and timing perfectly in sync. We’re based in Utrecht (NL) with a second office in Toronto (CA), and our 100+ team members work in a culture that’s open, flat, and inclusive, where curiosity drives us, ownership matters, and everyone has the freedom to challenge ideas and make an impact. Check out our public roadmap to see what’s coming next!

Mission of this role

Thousands of rental companies run their business on Rentman, and many of them depend on it talking smoothly to the rest of their stack: accounting packages, webshops, calendars, and our public API. When an integration breaks, invoices don’t sync, bookings go missing, and customers notice fast.

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.

What you'll do

• Join refinement with the Integrations team and write Gherkin (Given/When/Then) acceptance specs that developers turn into tests

• 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)

• Explore beyond the acceptance criteria to find edge cases, and file clear, reproducible bug reports in Jira

• 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

• 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

• Run release-day regression and the OWASP ZAP security scan, and give a clear go / no-go call

• Migrate the remaining legacy tests and decide what’s worth automating and what stays manual

• Coach developers so they own their tests, and organise QA days with the other product teams

   

What we are looking for

• 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), not only record-and-play tools

• 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

   

Nice to haves

• Experience with complex B2B SaaS, ideally with a public API or integration marketplace

• Contract testing (e.g. Pact) or mocking third-party services

• Playwright specifically, and Gherkin / BDD

• Experience leading a shift-left change

• Testing integrations with accounting or finance software

• Basic security testing (e.g. OWASP ZAP)

What you’ll get

• Competitive salary based on experience, plus 8% holiday allowance

• A results-based bonus based on company performance (up to a full 13th month's salary)

• 25 vacation days to recharge

• Earn an extra day of PTO for each year at Rentman, from your second anniversary up to five years.

• A 4-week paid sabbatical after 5 years to go on an adventure

• Flexible WFH policy & work from anywhere for 4 weeks a year

• Pension plan through BrightPensioen

• An annual training budget to grow your skills

• Access to OpenUp for mental well-being and personal growth

• Your choice of a shiny new Windows, Linux, or Mac

• Stay active with the team: join the Rentman football team, squash and padel, plus a discounted Urban Sports membership

• An OV Business card if you live more than 10km from the office

• An ambitious, inclusive, and diverse international team

• A flexible, energizing workplace with free lunches, office perks (PS5, ping pong, D&D), legendary karaoke nights, and regular team activities

• An amazing office in the heart of Utrecht, in the historic Drift 17
