Commercial Lead/Business Partner - Security

The Cabinet Office and HM Treasury operate at the heart of the UK government. These iconic departments are responsible for ensuring the effective running of government, maintaining control over public spending and working to achieve strong and sustainable growth for the UK.

The Cabinet Office & HM Treasury (COHMT) Commercial team has a vision to be a top performing commercial function in government, setting best practices for others to follow. It offers a unique challenge to commercial professionals who want to work on some of the UK’s most important policy issues. The team works in partnership with all areas of the business, providing a commercial service that covers planning, commercial strategy, sourcing and contract management on circa £1bn of third party spend.

The COHMT Commercial team operates with our core values in mind which are:

We are Curious, Collaborative and Kind, we act with Integrity and are Focused on value for money.

We are looking for a talented commercial professional to join the team and help to shape and influence commercial and procurement strategies within the department. This role will be challenging and hands-on, and will require expert stakeholder management skills as well as a strong grasp of commercial processes and the challenges of procuring goods and services in Central Government.

The COHMT commercial team has recently undergone a change to its operating model and is now organised into spend category teams which are supplemented by business partners and embedded commercial teams in specialist areas and programmes. The directorate is supported by a central team responsible for the overall strategy and enabling functions.

This role uniquely combines strategic business partnering activities with hands-on procurement delivery for a range of requirements. You will act as a senior commercial advisor to the business, providing expert commercial advice as part of the wider commercial team. You will be expected to provide commercial guidance and support to enable appropriate decision making and maximise value for money both in new procurement activity and existing supplier management, able to act under your own initiative and lead and drive commercial projects, engaging and influencing key stakeholders within your areas of responsibility.

At the same time, you will work with other commercial team members to enable continuous improvement and commercial capability development with your customers, working to implement new policies and processes as required. You will often be working on projects that require extra levels of sensitivity, making SC clearance a requirement for this role.
