Mission of this role

As an interim Senior QA Specialist at Rentman, you make sure every release reaches customers without regressions. You own the test strategy across our 3 product teams and finish moving regression testing from a manual release-day cycle to an automated, shift-left E2E suite. Without this role, quality depends on manual testing on release day, bugs show up in staging or production, and the move to automated testing stalls. This is an interim position: the duration is still to be confirmed, and the role ends once the assignment is complete.

What you'll do

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

Test new features on staging, going beyond the acceptance criteria to find edge cases, and file clear, reproducible bug reports in Jira

Write and review Playwright tests (TypeScript) in the frontend repo, and review developer-written tests in pull requests

Monitor the daily automated regression run in GitHub Actions, triage failures the same day, and fix flaky tests at the root cause

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

Migrate the remaining legacy tests and decide what is worth automating and what stays manual

Organise cross-team QA days and coach developers so they own their tests

What we are looking for

5+ years in QA on web applications

At least 2 years writing and maintaining UI test automation in code (Playwright, Cypress or Selenium, ideally TypeScript/JavaScript), not only record-and-play tools

Strong manual and exploratory testing, with bug reports developers can act on without follow-up questions

You have 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

Playwright specifically, and Gherkin / BDD

Experience leading a shift-left change or coaching developers to own their tests

API testing (REST, Postman or similar)

Basic security testing (e.g. OWASP ZAP)

Mobile app testing (iOS / Android)

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
