Test Engineer II

Role Description

We are looking for a proactive Test Engineer II to join our CS SES testing team in Amsterdam. In this role, you will work across cross-functional squads to test Pega workflows from an end-user perspective, with Customer Service agents as your primary focus. You will embed directly into Agile teams to drive risk-based testing, advocate for early testability, and build deterministic automated checks. If you are passionate about combining strong backend/API testing with low-code front-end applications and cutting-edge AI testing methodologies, this role offers an exciting opportunity to make a real impact on our operations.

Leadership/Team Quote:

"In Customer Service Software Engineering Services (CS SES), our focus is on empowering customer service agents with seamless Pega workflows so they can deliver world-class experiences to our travelers. As a Test Engineer on our team, you won't just execute tests—you will champion quality engineering, drive AI-driven testing innovation, and directly shape tools used by thousands of agents every day."

Key Job Responsibilities and Duties

• Independently execute test design, risk-based testing, and quality practices from initial design to release within cross-functional Agile squads.
• Guide teams to make features testable early, advocating for isolated verification, shift-left testing, and sustainable root cause analysis.
• Build and maintain deterministic, fast-feedback test automation for APIs and backend services using tools like Rest Assured, Playwright, or Postman.
• Test and validate end-to-end Pega customer service workflows from an agent perspective while integrating non-functional checks such as performance, accessibility, security, or resiliency.
• Explore, implement, and test AI features and LLM models within testing workflows, using tools such as Claude Code or similar frameworks.
• Coach and mentor less experienced test engineers on testing best practices, testability, and continuous quality improvements.
• Collaborate closely with cross-functional squads and partner teams to communicate quality trade-offs clearly to both technical and business stakeholders.

Qualifications & Skills

• Strong experience in test design, execution, and test automation across the full software delivery lifecycle in Agile environments.
• Proven hands-on experience in backend and API testing alongside front-end testing for low-code platforms.
• Practical experience with relevant test automation tools and frameworks such as Playwright, Rest Assured, and Postman.
• Demonstrated understanding of testing AI/LLM models and practical experience using AI tools such as Claude Code to enhance testing practices.
• Solid understanding of risk-based testing, exploratory testing, non-functional testing, and observability/troubleshooting techniques.
• Strong coaching, communication, and stakeholder management skills with a dedicated customer and end-user mindset.
• Familiarity with Pega product architecture and workflows is a plus.
