• Support procurement and subcontracting activities, ensuring commercial alignment and value for money.
• Develop management information and reporting for senior governance forums.
• Support mobilisation leadership teams with commercial decision-making and strategic advice.
• Facilitate effective transition from mobilisation into operational service delivery.

What you’ll need to do the role:

• Significant experience managing complex commercial or public sector contracts.
