Statement of Work

 

Requirement Title: Senior Solution Engineer

 

Requirements Description: 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.

 

Duties & Role:

 

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 asoperated 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.

 

Requirements Description: Essential Qualifications

 

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

 

Essential Professional Experience

 

Complex Systems Engineering

 

Significant experience in the architecture, design, integration,

 

verification or lifecycle management of complex systems involving

 

multiple technical domains.

 

Demonstrated ability to translate operational or business needs

 

into system requirements, architectures and implementable

 

technical solutions.

 

Experience defining and managing system boundaries; functional

 

decomposition; interfaces; dependencies; constraints; nonfunctional requirements; system-level performance

 

Skill, Knowledge & Experience:

 

Technical Leadership

 

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

 

Ability to provide clear technical direction

 

Experience resolving technical disagreements and driving

 

engineering decisions across organizational and technical

 

boundaries.

 

System Integration

 

Significant experience integrating systems composed of multiple

 

technologies, products or engineering disciplines.

 

Strong understanding of system interfaces, dependencies and

 

emergent behaviour.
