Responsibilities include:

• Develop and manage sustainment strategies – Plan maintenance, upgrades, and obsolescence management while integrating with Defence asset frameworks.
• Oversee programs and contracts – Manage sustainment services, monitor budgets, ensure compliance, and govern complex technical contracts, including international agreements.
• Maintain stakeholder relationships – Collaborate with internal and external stakeholders, international allies, and industry partners in space domain awareness and control.
• Ensure technical integrity and resource management – Support system calibration, documentation, configuration control, and oversee logistics for specialised components and secure data pathways.

• Resource & Risk Management – Expertise in logistics, supply chain management, asset lifecycle planning, and assessing risks in interconnected systems.
