About the role

Job summary

The Corporate Services Modernisation (CSM) Programme requires a Business Case Approvals Manager to support the planning, development and progression of business cases through Ministry of Defence governance and investment approval routes.

The role will work across the programme to ensure business cases and approval documents are coherent, evidence-based and aligned to departmental approval requirements and HM Treasury Green Book principles.

This role is suited to someone who can bring structure, clarity and pace to business case approvals activity. You will coordinate inputs from multiple stakeholders, manage approval conditions and supporting evidence, advise colleagues on investment approvals and help ensure the programme is positioned for successful decisions at the right time.

CSM is a high priority for the Ministry of Defence and offers substantial exposure to senior level decision-making and therefore offers opportunities for further career development.

The CSM portfolio is recruiting to two-year FTAs, with the possibility of extension subject to business requirements and approvals.

If you are a permanent MOD civil servant and are successful in securing an advertised Fixed-Term Appointment (FTA), it may be possible to agree a Temporary Transfer, subject to the agreement of your current MOD business area. Where a Temporary Transfer is agreed and the post is at a higher grade, any promotion will be temporary, and you will return to your substantive grade at the end of the Temporary Transfer.

Existing Civil Servants from outside MOD and applicants from accredited NDPBs are eligible to apply but will only be considered on a loan basis (Civil Servants) or secondment (accredited NDPBs). Prior agreement to be released on a loan basis must be obtained before commencing the application process. In the case of Civil Servants, the terms of the loan will be agreed between the home and host department and the Civil Servant, including arrangements regarding grade on return.

The role is advertised as 37 hours per week. Part-time and Job share may be considered providing that full time hours are covered.
