Looking for a role where you can develop, optimize, and own a business-critical ServiceNow platform? Do you enjoy complex scripting, platform upgrades, and building scalable solutions that support real business processes? Make your career count as a Senior ServiceNow Developer at BDO, where expertise, a hands‑on mindset, and a warm, pragmatic culture come together.

As a ServiceNow Developer, you’ll be part of a small but fast‑growing team that fully owns the ServiceNow platform. The platform is a strategic pillar within BDO and continues to expand across multiple business processes. You’ll work independently, collaborate closely with stakeholders, and actively shape the platform’s future.

What will you be doing?

• Supporting end users and key users with incidents, questions, and small changes.
• Developing and debugging complex scripts, including Client Scripts, Business Rules, Script Includes, Flow Designer, and IntegrationHub.
• Working in an agile setup, translating epics into stories and delivering in sprints.
• Contributing to projects that introduce new functionality or extend existing and new modules.
• Developing in a dev environment and migrating changes correctly via update sets or scoped applications.
• Participating in platform and module upgrades (ITSM, CSM, WSD), including preparation, testing, clone‑backs, and post‑upgrade checks.
• Phasing out or replacing legacy custom applications when needed.
• Maintaining documentation and sharing knowledge within the team.
• Continuously learning about new ServiceNow modules, features, and best practices.
• Actively contributing ideas around performance optimization, governance, and platform improvements.

• Experience with update sets, scoped applications, and application lifecycle management.
• Hands‑on experience with ServiceNow upgrades, including cloning, testing, and upgrade‑related processes.
• Solid knowledge of ITSM; experience with CSM and WSD is a strong plus.
• ServiceNow certifications (CSA, CAD, CIS‑ITSM, micro‑certifications) are an asset, not a must.
• Fluent communication skills in English and Dutch or French.
• Willingness to work part of the week from our Zaventem office, combined with home working.
• Motivation to continuously grow your expertise as new modules and features are activated.

What do we bring to the table?

• Culture: Join a team of experts who value respect, collaboration, and ownership. Our culture is open, you can speak to anyone, at any level.
• Development: Shape your career with access to training, certifications, and continuous learning opportunities.
