Senior System Engineer – Infrastructure & Cloud

About the Role

At Van Bael & Bellis, we see technology as a core driver of our success in international law. As our Senior System Engineer, you won’t just be maintaining systems, you will play a key role in shaping, optimizing, and securing our infrastructure and cloud ecosystem.

We are looking for a proactive technical expert who enjoys diving deep into challenges, uncovering root causes, and taking ownership of solutions through to resolution.

Reporting directly to our Head of ICT, you will work closely with our ICT team and specialized technology partners to translate our IT strategy into robust technical solutions across infrastructure, cloud, digital workplace, and cybersecurity.

What You Will Do

In this role, you will combine high-level technical engineering with meaningful involvement in the continued evolution of our IT environment:

• Infrastructure & Cloud Excellence: Maintain and continuously improve our Microsoft 365, Azure, Windows Server, and VMware environments.

• Security & Resilience: Strengthen identity and access security across Entra ID, MFA and Conditional Access, as well as endpoint protection and infrastructure hardening. You will contribute to our continuous vulnerability assessment and security testing processes, investigate identified findings and implement appropriate remediation and hardening measures where required. You will also work with our SOC and security partners to review technical findings, alerts and improvement recommendations and translate them into concrete technical actions.

• Design & Implementation: Participate in infrastructure, cloud and security projects from technical design through to implementation.

• Automation & Standardisation: Identify opportunities to reduce manual work and improve reliability using modern automation tools.

• Technical Ownership: Work closely with specialised external partners while maintaining strong technical knowledge and ownership within our internal ICT team.

• Core Business Platforms: Help ensure the availability, performance and resilience of the infrastructure supporting our business-critical applications and cloud services.

• Compliance: Provide technical input and evidence supporting our ISO Information Security and Business Continuity frameworks.

What We Are Looking For

You bring solid experience as a System Engineer, including senior/L3-level responsibilities, together with a strong problem-solving mindset and hands-on expertise in:

• Core Stack: Microsoft 365 · Entra ID · Active Directory · Intune · Windows Server · VMware · Networking · Backup & Recovery · Endpoint & Infrastructure Security

• Valued Extras: Experience with Azure, Cisco Meraki, Veeam, PAM, SOC/SIEM, vulnerability management, or working within security/compliance frameworks is a strong advantage.

• Languages: Professional fluency in English is essential; knowledge of French or Dutch is a strong advantage.

Beyond the tech, we value how you work:

• Ownership: You take responsibility for technical challenges and follow them through to resolution.

• Analytical Curiosity: You enjoy understanding the why behind complex technical issues rather than simply treating the symptoms.

• Autonomy & Clarity: You work independently while keeping colleagues informed and communicate clearly with both technical and non-technical stakeholders.

• Pragmatic Balance: You understand how to balance security, operational stability and user experience.

• Continuous Improvement: You naturally look for opportunities to simplify, automate and improve the environment rather than accepting “that’s how we’ve always done it.”

Why Join Van Bael & Bellis?

• Trust & Flexibility: We offer flexible working hours, home-working options, and a calm, professional, and supportive atmosphere where professionals are trusted to manage their responsibilities.

• Innovation-Driven: With continuous investment in cloud, cybersecurity, automation and digitalisation, you will have the opportunity to contribute directly to the evolution of our IT environment.

• End-to-End Technical Exposure: Rather than being boxed into a single technology area, you will work across a broad infrastructure and cloud ecosystem.

• Broad Impact & Direct Alignment: Reporting directly to the Head of ICT, you will play a hands-on role in executing strategic IT initiatives, translating high-level goals into concrete technical solutions with real influence on operational success.
