Job description

Are you ready to connect complex systems and make data flow seamlessly across a dynamic IT landscape? As an Integration Specialist, you play a central role in designing and building integrations that support critical processes in domains such as finance, supply chain, marketing and HR.

You work at the heart of the organization, where applications, platforms and teams come together. Using modern integration technologies relying on our Integration Platform (Mulesoft), you help shape a scalable and future-proof integration landscape. You contribute not only by delivering solutions, but also by improving the way the team works and by helping define the technical direction for the future (think of the use of AI).

Key responsibilities

• Designing integration architectures and creating API specifications aligned with team standards.
• Developing and implementing MuleSoft integrations, including reusable and deployable assets.
• Delivering high-quality Unit tests as part of integration solutions.
• Creating clear and structured technical documentation according to team guidelines.
• Contributing to integration improvements from the backlog and supporting ongoing changes.
• Helping improve processes, ways of working and the long-term integration vision.

You are an integration professional who thrives in a collaborative environment, is able to work independently, and takes ownership of delivering reliable and scalable solutions. You combine technical expertise with a proactive mindset and a drive to continuously improve.

Qualifications

• 3 to 5 years of experience in designing and developing integrations.
• Strong knowledge of APIs and web services, including XML and JSON.
• Experience with CI/CD implementation and deployment processes.
• Experience working with integration platforms such as MuleSoft.
• Ability to translate requirements into scalable technical designs.

For this position, a pre-employment screening is required, consisting of a Certificate of Conduct (VOG) and a background/integrity check. Due to the access to sensitive (financial) information and customer data, we place great importance on a careful assessment. The screening must be successfully completed before you can start your employment with us. We reimburse the cost of the VOG application and, of course, handle your data with care in accordance with our privacy statement.
