Job summary

Brevco Services in Belgium seeks a Senior Systems Engineer to lead systems engineering for complex, highly integrated technical systems across ICT/CIS, defence and telecom domains.

The role emphasizes MBSE, architecture definition, and lifecycle ownership, with a focus on translating operational needs into robust, end-to-end solutions. English proficiency required for technical documentation and collaboration.

Qualifications

• University degree in Systems Engineering, Telecommunications Engineering, Computer Engineering, Electronic Engineering, Computer Science or another relevant discipline (Mandatory)
• 10 years of relevant professional engineering experience, including significant experience with complex ICT/CIS, defence, aerospace, telecommunications or other highly integrated technical systems. Experience in Systems Engineering and/or Solution Architecture applied to complex systems (Mandatory)
• Professional working proficiency in English, including the ability to produce and review complex technical documentation (Mandatory)
• Complex Systems Engineering (Mandatory)
• Demonstrated ability to translate operational or business needs into system requirements, architectures and implementable technical solutions (Mandatory)
• Experience defining and managing system boundaries; functional decomposition; interfaces; dependencies; constraints; non-functional requirements; system-level performance (Mandatory)
• Experience as a Technical Lead, Lead Systems Engineer, Solution Architect, System Architect or equivalent senior engineering role. Experience technically coordinating multidisciplinary engineering teams and SMEs (Mandatory)
• Ability to provide clear technical direction (Mandatory)
• Experience resolving technical disagreements and driving engineering decisions across organizational and technical boundaries (Mandatory)
• Significant experience integrating systems composed of multiple technologies, products or engineering disciplines (Mandatory)
• Strong understanding of system interfaces, dependencies and emergent behaviour (Mandatory)
• Experience identifying and resolving integration problems spanning multiple technical domains (Mandatory)
• Experience planning or supporting system integration, verification, validation and acceptance activities (Mandatory)
• Demonstrated ability to perform structured root-cause analysis Lifecycle Engineering / Product Ownership (Mandatory)
• Experience supporting complex systems after their transition into operational service (Mandatory)
• Understanding of the relationship between: design authority; configuration management; change management; obsolescence; technology refresh; technical debt; operational support; system evolution (Mandatory)
• Experience assessing the system-level impact of changes to individual components, subsystems or services (Mandatory)
• Broad technical understanding across ICT/CIS domains, rather than being specialists exclusively within one technology. Strong knowledge of several of the following areas is expected: (Mandatory)
• IP networking and routing; LAN/WAN architectures; network security and firewalls; compute and server infrastructure; virtualization and hyperconverged infrastructure; storage technologies; identity and access management; cybersecurity architectures; enterprise and infrastructure services; cloud and hybrid-cloud technologies; automation and orchestration; monitoring and management systems; telecommunications; SATCOM and/or radio communications; deployable or mobile ICT infrastructure (Mandatory)
• The candidate is not expected to be the SME in all these domains. However, they must have sufficient technical breadth to understand how these technologies interact (Mandatory)
• Strong understanding of requirements engineering, including functional and non-functional requirements (Mandatory)
• Ability to decompose complex systems into manageable subsystems and components while preserving understanding of the complete system (Mandatory)
• Strong understanding of interfaces and Interface Control. Experience with requirements traceability from operational need through implementation and verification (Mandatory)
• Understanding of architecture versus detailed design and the appropriate allocation of responsibilities between system-level and domain engineers (Mandatory)
• Experience performing engineering trade-off analyses (Mandatory)

Responsibilities

• System and Solution Engineering: Analyse operational, functional & project requirements & translate them into implementable DCIS solutions
• Define the overall technical solution and system architecture using the established DCIS Node, Module & Service taxonomies
• Ensure that the resulting system delivers the required end-to-end functionality & emergent behaviour
• Perform technical trade-off analyses considering performance, interoperability, security, deployability, resilience, maintainability, cost, schedule & technological maturity
• Model Based Systems Engineering: Apply MBSE throughout the engineering lifecycle
• Map project requirements against existing Requirement Models, Implementation Guidelines & Implementation Constraints. Maximise reuse of approved Modules, Services, architectures & engineering patterns
• Identify gaps where existing Requirement Models or standardized building blocks cannot satisfy project requirements
• Complex Systems Product Ownership – Operational Nodes: act as the Complex Systems Product Owner
• Maintain technical ownership and system-level design responsibility for assigned operational Nodes throughout their lifecycle
• Maintain an authoritative understanding of the Node architecture, configuration, interfaces, dependencies, capabilities & design constraints
• Ensure that modifications to individual Modules or Services do not compromise the overall coherence, interoperability, performance, security or operational capability of the Node
• Assess operational technical issues from an end-to-end system perspective & coordinate their resolution with the appropriate SMEs, Model Custodians & service organizations
• Analyse requests for change, obsolescence issues, technology refreshes, security changes & evolving operational requirements to determine their impact on the complete Node
• Define & maintain the technical evolution path & Node roadmap, aligned with Module & Service roadmaps & the wider DCIS Target Architecture
• Identify technical debt, architectural divergence, lifecycle risks & emerging obsolescence before they become operational constraints.Initiate or recommend engineering activities required to maintain the technical viability of the Node
• Provide system-level technical guidance to operations, maintenance & service-management organizations where issues require design-level knowledge
• Ensure that operational experience & lessons identified are fed back into the Modularity Framework, Requirement Models & future system designs
• Maintain consistency between the as-designed, as-built and as-operated technical baselines of the Node
• Support configuration & change-control processes by assessing the system-level impact of proposed changes
