Your New Role And Responsibilities
As a Systems Engineer, you will be part of a high‐performing engineering delivery team supporting the sustainment and evolution of complex systems. You will operate under general direction and be responsible for the reliable execution of assigned systems engineering activities across investigation, analysis, design, and change implementation within established engineering and assurance frameworks.
Working within secure and complex environments, you will apply sound systems engineering principles to support sustainment activities, system changes, and engineering investigations. You will collaborate closely with software engineers, architects, project teams, and stakeholders to define requirements, develop engineering artefacts, manage technical risk, and progress systems through defined engineering governance and assurance gates.
This role provides the opportunity to contribute to nationally significant systems while supporting the continuous improvement of engineering quality, assurance, and delivery practices.
Key Responsibilities Include
Conduct engineering investigations and systems analysis to support defect resolution, capability enhancements, sustainment decisions, and system changes
Define, develop, and implement Engineering Change Proposals (ECPs) through established engineering gates and assurance processes
Develop and maintain systems engineering documentation, including requirements, design artefacts, impact assessments, and traceability evidence
Collaborate with configuration management, architects, engineers, and stakeholders to support change control, configuration integrity,



and delivery outcomes
Support verification, validation, and technical risk management activities, including issue escalation and design justification
Ensure compliance with security, quality, engineering governance, project management, and ITIL‐aligned service management frameworks while contributing to continuous improvement initiatives
What You'll Bring To Make An Impact
Bachelor's degree in Systems Engineering, Engineering, Information Technology, or related discipline, or equivalent industry experience
Demonstrated systems engineering experience within complex project, sustainment, enterprise, Defence, or government environments
Strong understanding of systems engineering principles, lifecycle management, requirements analysis, and system design in secure environments
Experience supporting engineering assurance, verification and validation, configuration management, and engineering change processes
Proven ability to manage technical risks, contribute to engineering decision‐making, and work across multiple stakeholders and technical domains
Strong communication and collaboration skills, with experience working in Agile or hybrid delivery environments and producing high‐quality engineering documentation
