Senior Test Engineer

Function

We’re looking for an experienced Test Engineer to join our client’s Agile delivery team. You’ll play a key role in safeguarding the quality of a complex, backend-driven distribution platform by designing and executing robust tests, with a strong focus on automation. This is a hands-on role for someone who enjoys working close to developers in technically demanding environments.

The Role

As Test Engineer, you are responsible for validating software quality across multiple test levels. Given the non-UI, backend nature of the systems involved, you will actively drive test automation and help shape a mature, scalable QA approach within the team.

Key Responsibilities

• Execute mainly technical tests at different levels (integration, system, end-to-end)

• Design, introduce, implement, and continuously improve test automation tooling

• Build and maintain long-running end-to-end tests in complex, distributed systems

• Collaborate closely with developers, product owners, and business analysts as part of a Scrum team

• Contribute to the continuous improvement of software quality and QA maturity across teams

Profile & Experience

Must-have

• Comfortable working in a highly technical, developer-oriented environment

• Proven experience testing complex, distributed, backend systems

• Solid understanding of asynchronous processing

• Basic knowledge of SQL and ability to validate data at database level

• Experience testing batch-oriented, non-interactive systems

• Strong communication skills with both technical and business stakeholders

• Languages: English (fluent), Dutch (basic), French (basic)

Nice-to-have

• Experience testing high-volume data pipelines

• Basic knowledge of Kafka or similar messaging platforms

• Experience with test automation for non-UI systems (scripts, controlled replays)

• Ability to read, analyze, and interpret log files

If you enjoy improving test automation in technically complex environments and want to make a real impact on software quality, this role at our client could be a strong next step.
