For our customer we are looking for an Senior Security Engineer (Security Architecture Focus)
Start Date: asap
Man Days: 110+
Location: Zwijnaarde
Languages: NL & ENG
Remote Politics: Flexible
Overview
Responsible for the design, implementation, and alignment of security controls across the organization, with a focus on security engineering, architecture, and cross-domain integration.
Acts as a bridge between technical security tooling, operational needs, and strategic initiatives.
Summary of Responsibilities
* Security engineering and tooling integration
* Email security ownership (Mimecast, MDO, DMARC, phishing controls)
* Vulnerability and exposure management (Qualys, Defender TVM, pentests)
* Cloud and data security support (CSPM, DLP)
* Network visibility and detection (e.g., Darktrace)
* Security architecture alignment across domains
* Contribution to strategic initiatives (e.g., SASE, LSAAF SAS)
* Coordination with SOC, infrastructure teams, and vendors
* Risk identification, tracking, and transparency
Important Positioning – What Defines the Right Profile
While the responsibilities above describe the scope of the role, they are not sufficient criteria to identify the right candidate.
What differentiates the right profile is the depth of technical foundation combined with broad cross-domain expertise, built over time and validated through both experience and certifications.
Key Differentiators:
Strong Technical FoundationsEarly exposure to electronics and low-level programming
* Deep understanding of how systems and networks work internally
* Ability to go beyond tooling and understand root causes
Infrastructure BackgroundBachelor in IT (System Administration)
* Hands-on experience in infrastructure and networking
* Not starting directly in "security-only" roles
Formal Cybersecurity SpecializationSpecialized Bachelor in Cybersecurity
* Structured and comprehensive view across security domains
Extensive Certifications (Critical Differentiator)
The profile is strongly reinforced by a broad and coherent certification path, demonstrating both depth and cross-domain coverage:
* CiscoCisco CCNP (expired but still highly relevant as proof of networking depth)
* CompTIA Certifications (Full Track)CompTIA Cloud Admin Professional
* CompTIA Network Infrastructure Professional
* CompTIA Linux Network Professional (incl. LPIC-2 level)
* CompTIA Secure Infrastructure Specialist
* CompTIA Secure Infrastructure Expert
* CompTIA Secure Cloud Professional
* CompTIA Security Analytics Professional
* CompTIA Network Vulnerability Assessment Professional
* CompTIA Network Security Professional
* These collectively demonstrate:Strong networking foundation
* Solid infrastructure knowledge
* Cloud and security expertise
* Analytical and vulnerability management capabilities
* Other CertificationsISC2 SSCP
* LPIC-2 (Linux Professional Institute)
* IT Service ManagementITIL v4 Foundation
* ITIL v5 Foundation
* These add:Operational maturity
* Understanding of processes, service management, and governance
Why This Matters
* This role cannot be filled effectively by:
* A tool-driven engineer
* A narrowly specialized security profile
* A candidate lacking foundational IT knowledge
* Instead, it requires someone who can:Understand systems end-to-end
* Bridge infrastructure, cloud, and security domains
* Identify gaps between tools and processes
* Translate technical reality into architectural decisions
Short Positioning Statement (Strong Version)
"This role is often described through its responsibilities, but in practice the differentiator is not tool ownership or individual domains. It is the combination of deep technical foundations (electronics, low-level programming, infrastructure), formal cybersecurity specialization, and a broad set of advanced certifications — particularly across the full CompTIA security, infrastructure, and cloud tracks, combined with ITIL service management knowledge."
