• Automating test cases (automated for APIs, manual and automated for UIs) with the right tools for each technology and need
• Supporting the teams and helping estimate the test effort for projects
• Improving testing processes and test deliverables
• Performing functional and non-functional testing, end-to-end testing with external partners, and supporting user acceptance testing

• Experience working in Agile environments; familiarity with public administration systems is a plus
• Fluent in Dutch and English or French and English, with at least a basic knowledge of the third language
