• Coordinate onboarding across multiple service commencement dates and transition activities.


• Produce reusable process documentation, governance packs and supplier guidance materials.


• Support operational readiness activities, including readiness assessments and onboarding across core IT service management processes.


• Help ensure continuity between incumbent providers and newly onboarded suppliers.

• Active MOD SC Clearance, used within the last 12 months.

• Previous experience within Defence or other highly regulated, secure environments.

• Contract opportunity within a major Defence programme.
