A multinational defence organisation in Braine-l'Alleud builds deployable communication and information systems out of standard modules and services. It needs a senior solution engineer who can see the whole system at once - turning requirements into architecture, coordinating the specialists, and acting as technical owner of systems already in operational service. What you would be doing Translating operational and project requirements into implementable solutions and a clear system architecture Applying model-based systems engineering, reusing approved building blocks and flagging the gaps where they fall short Running trade-off analyses across performance, interoperability, security, resilience, cost and schedule Acting as product owner for systems already in service: assessing changes, obsolescence and technology refresh against the whole system, and keeping its roadmap current Integrating contributions from networking, SATCOM and radio, compute and cloud, storage, cybersecurity and identity specialists into one coherent design Being the technical focal point for your projects and driving conflicting requirements to a decision What you would bring A degree in systems, telecommunications, computer or electronic engineering or computer science, and around 10 years of engineering experience on complex ICT, defence, aerospace or telecoms systems Proven work as technical lead, lead systems engineer or solution architect Strong requirements engineering, interface control, traceability and system integration, verification and acceptance Broad technical range across networking, infrastructure, virtualisation, security, cloud, automation and communications - you understand how they interact, without needing to be the expert in each Experience with systems after they go live: configuration and change management, obsolescence and technical debt Professional English, including writing and reviewing complex technical documents Why this one is worth a look It is a system-level seat with real design authority, on deployable systems that have to work first time in the field.
