• 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
