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
