Commercial Security and Information Assurance Lead

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.

We are looking for an experienced Information Assurance/Cyber Security professional to join the team. This role will be responsible, alongside the Head of Commercial Information Assurance, for working with Business Units and the Commercial Team to ensure that Cabinet Office contracts have proportionate and robust contractual security requirements included in each procurement and that security elements of large contracts are successfully managed.

This role will be challenging and hands-on, and will require expert knowledge of security architectures, information assurance and information risk management. Some knowledge of commercial processes and supply chain management from a security perspective is desirable.

You’ll support the Head of Commercial Information Assurance to deliver secure outsourced services and systems. This includes providing specialist advice and expertise for risk management decision making by senior risk owners.

The role involves supporting both projects procured for Cabinet Office themselves and those procured by Cabinet Office for use by the rest of government. The role involves working closely with suppliers, commercial teams, legal advisors, and colleagues from across the public sector.

The post sits in the Commercial Directorate and reports to the Head of Commercial Information Assurance. This role will require close working relationships across all the Business Units in the CO and across HM Government to ensure departmental and cross departmental information risks are assessed and effectively managed. This specialist role requires technical cyber security and risk management skills and knowledge.

This role can be based in London, York, Glasgow, or Manchester and allows for hybrid working arrangements with a minimum of 3 days in the office per week. An additional digital skills payment may be applied for with a technical skills assessment which is reviewed annually.
