About this role

- You will ensure that risks arising from third parties are identified, assessed, and managed proportionately across the full commercial lifecycle—from procurement and onboarding through to contract management and offboarding.
- A key part of the role is working closely with Commercial, Legal, and Service Teams to ensure that security is embedded into government procurement processes, with a strong understanding of how to apply security requirements through contractual mechanisms.
