For our customer we are looking for an Senior Security Engineer (Security Architecture Focus)Start Date: asapMan Days: 110+Location: ZwijnaardeLanguages: NL & ENGRemote Politics: FlexibleOverviewResponsible 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 ResponsibilitiesSecurity engineering and tooling integrationEmail 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 domainsContribution to strategic initiatives (e.G., SASE, LSAAF SAS)Coordination with SOC, infrastructure teams, and vendorsRisk identification, tracking, and transparencyImportant Positioning – What Defines the Right ProfileWhile 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 programmingDeep understanding of how systems and networks work internallyAbility to go beyond tooling and understand root causesInfrastructure BackgroundBachelor in IT (System Administration)Hands-on experience in infrastructure and networkingNot starting directly in "security-only" rolesFormal Cybersecurity SpecializationSpecialized Bachelor in CybersecurityStructured and comprehensive view across security domainsExtensive 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 ProfessionalCompTIA Network Infrastructure ProfessionalCompTIA Linux Network Professional (incl. LPIC-2 level)CompTIA Secure Infrastructure SpecialistCompTIA Secure Infrastructure ExpertCompTIA Secure Cloud ProfessionalCompTIA Security Analytics ProfessionalCompTIA Network Vulnerability Assessment ProfessionalCompTIA Network Security ProfessionalThese collectively demonstrate:Strong networking foundationSolid infrastructure knowledgeCloud and security expertiseAnalytical and vulnerability management capabilitiesOther CertificationsISC2 SSCPLPIC-2 (Linux Professional Institute)IT Service ManagementITIL v4 FoundationITIL v5 FoundationThese add:Operational maturityUnderstanding of processes, service management, and governanceWhy This MattersThis role cannot be filled effectively by:A tool-driven engineerA narrowly specialized security profileA candidate lacking foundational IT knowledgeInstead, it requires someone who can:Understand systems end-to-endBridge infrastructure, cloud, and security domainsIdentify gaps between tools and processesTranslate technical reality into architectural decisionsShort 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."
