• Support the development and execution of the ITEA Plan, ensuring all requirements are testable, verifiable, and aligned with military training outcomes.
• Manage requirements change control, assessing impacts across verification, validation, assurance, and capability acceptance.
• Establish and operate a robust defect tracking and resolution process across all ITEA phases, including simulation environments and training platforms.
• Link defects to related requirements and test outcomes to support root cause analysis and continuous improvement of training systems.
• Prioritise and categorise defects based on operational impact, training effectiveness, and programme milestones.
• Provide regular defect status reporting to stakeholders, including MOD representatives and delivery partners.
• Collaborate with Engineering Leads, Test Lead, and military SMEs to ensure requirements and defects are fully integrated into verification and validation activities.
• Maintain the Verification and Validation Requirements Matrix (VVRM) to track coverage, compliance, and readiness for capability deployment.
• Produce and present metrics and dashboards on requirements coverage, defect trends, and readiness for acceptance into service.
• Contribute to ITEA reviews, readiness assessments, and governance forums, supporting MOD assurance and audit requirements.
• Act as a key interface between engineering, testing, assurance, and delivery teams to ensure shared understanding of requirements and defect status.
• Support user acceptance testing (UAT), operational trials, and field validation by ensuring requirements and defects are accurately reflected in test artefacts and training scenarios.

You’ll have a mission focus, and the enthusiasm and drive to ‘get things done’. You’ll want to work in collaboration with other defence training organisations, and the British Army. You won’t let bureaucracy get in the way of what needs to be done, you’ll learn lessons and share these lessons across the team. You’ll understand what it means to put the mission first.
