## About the Role

* You hold a Master of Engineering, Computer Science or Systems Engineering and have at least 12 years of professional experience in defence systems engineering, including several years as System, Solution or Technical Architect (or Design Authority) in a system-of-systems environment.
 * You have proven experience on Electronic Warfare and/or C4I / C4ISR solutions, ideally both, from requirements and design through integration, test and customer acceptance.
 * You master architecture frameworks and modelling approaches (Arcadia/Capella, NAF, SysML) and have solid knowledge of NATO interoperability standards (FMN, STANAGs) and of cybersecurity principles.
 * You have a strong knowledge of the military domain and operational analysis, and of the functions and performance of sensors (radars, passive electromagnetic sensors, optronics), weapon systems and command and control systems.
 * You are fluent in English (French and/or Dutch is an asset), you lead through influence and co-engineering, and you are eligible for a security clearance.

## Description

* Establish the architecture vision for Electronic Warfare (EW) and C4I solutions: identify stakeholders' concerns and operational needs, and define the system's boundary, context and external interfaces within multi-domain mission ecosystems.
 * Define, evaluate and recommend candidate architectures, and establish the solution architecture through trade-offs between operational expectations, technical and technological solutions, costs, product policy, risks and schedule; document the associated artefacts and approve the resulting lower-level specifications.
 * Act as the technical reference of the solution in bids, design reviews and customer meetings, shaping the technical offer and supporting cost and risk estimations.
 * Drive the integration of sensors and effectors (ESM/ELINT, COMINT, radar, EO/IR, countermeasures) into C2 and collaborative combat architectures, ensuring interoperability through NATO standards.
 * Manage, throughout the project lifecycle, the key and critical requirements (in particular KPIs, KPPs, interoperability and cybersecurity), the technical negotiation between stakeholders and the architectural changes, while coaching engineers and promoting a model-based co-engineering approach.
