Duties & Role:
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.
- 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.
- 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.
- 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.
- 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.
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.
- 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.
- Professional working proficiency in English, including the ability to produce and review complex technical documentation
