Build reliable HR-tech that truly empowers people

At the intersection of quality, speed, and innovation, we’re looking for a Senior QA Engineer who’s ready to shape the way we build and release software.

Why this role stands out

You’ll be part of a multidisciplinary Feature Team within a larger Engineering department. We work Agile–Scrum, delivering software in short, high-quality iterations. Your expertise in test automation helps us move faster, minimize risk, and build confidence into every release.

What you’ll do

Automate with impact

Design, build, and maintain test suites at every level — unit, integration, contract, application, and E2E.
Work with modern frameworks like Cypress, Playwright, JUnit/TestNG, NUnit, Pact, and REST Assured.

Quality as a mindset

Apply your knowledge of test design, risk analysis, and system architecture to deliver software that’s reliable, secure, and scalable.

Raise the bar together

Take an active role in Scrum ceremonies and help shape acceptance criteria and quality standards.
Create and maintain automated tests in JavaScript and Java — seamlessly integrated into our CI/CD pipeline.

Beyond functional testing

Validate performance, security, and resilience using the right tools.
Share insights within our global QA community and help define quality strategy across teams.

Culture of continuous improvement

Champion Trunk Based Development and an automation-first mindset to make delivery faster and safer.

What should you bring?

8+ years of QA experience, including 3+ years focused on automation.
Strong background with frameworks such as Cypress, Playwright, JUnit, TestNG, REST Assured, and Pact.
Solid understanding of frontend (Angular/AngularJS) and backend (Java) systems.
Experience with cloud environments, ideally AWS.
Familiar with CI/CD tools like GitHub Actions, Jenkins, or GitLab CI.
Interest in AI-driven testing and intelligent automation.
Deep understanding of Agile-Scrum and Trunk Based Development.
Analytical mindset with great attention to detail.
Strong communicator who thrives in collaborative teams.

Why you’ll love working here

Impactful role within a fast-growing HR-tech scale-up.
Freedom to innovate and bring your ideas to life.
A team that learns, shares, and celebrates success together.
Hybrid work setup, modern tools, and a culture built on trust.

Important

To be considered for this role, you must live in the Netherlands and have a valid work permit.
Remote applicants from outside the Netherlands will not be considered.

Mobility budget or Lease car: No
