Full Time On-Site: Yes

Time On-Site: 100%

Total Scope of the request (hours): 300

Required Start Date: 30 November 2026

End Contract Date: 31 December 2026

Required Security Clearance: NATO SECRET

Duties & Role:

1. 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.

2. 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.

3. Complex Systems Product Ownership – Operational Nodes

• For designated Nodes already introduced into operational service, 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.

4. Multi-Domain Technical Integration

• Integrate engineering contributions across DCIS technical domains, including as applicable:
• Network & Communication Access; WAN/LAN and network services; SATCOM & tactical communications; Radio systems; Infrastructure & Platform services; compute, virtualization & cloud technologies; storage & data services; cybersecurity & security services; identity & access management; Business Support Services; automation, orchestration & Infrastructure-as-Code; physical deployable infrastructure & associated supporting systems.

5. Technical Coordination

• Act as the primary technical focal point for assigned projects & operational Nodes.
• Coordinate the engineering contributions required from the different technical domains.
• Translate system-level requirements & operational issues into clear engineering tasks & technical questions for the appropriate SMEs & Model Custodians.
• Integrate the outputs produced by the different engineering disciplines into a single coherent solution. Identify conflicting requirements, assumptions or design decisions & drive their technical resolution.

Travel: Possible travel to other Agency & NATO sites within Belgium up to 1 - 2 times per month

Requirements

Skills, Knowledge & Experience:

• The candidate must have a currently active NATO SECRET security clearance

• University degree in Systems Engineering, Telecommunications Engineering, Computer Engineering, Electronic Engineering, Computer Science or another relevant discipline.
