Finance Manager - AI Security Institute

The AI Security Institute is the world's largest and best-funded team dedicated to understanding advanced AI risks and translating that knowledge into action. We’re in the heart of the UK government with direct lines to No. 10, and we work with frontier developers and governments globally. We’re here because governments are critical for advanced AI going well, and UK AISI is uniquely positioned to mobilise them. With our resources, unique agility and international influence, this is the best place to shape both AI development and government action. Our Finance team is the operational backbone that enables our researchers and policy experts to keep pace with the speed of AI development. We are building a high performing finance team that can transform traditional government finance operations into streamlined, efficient processes and support senior leaders with critical business planning and insights to enable us to deliver against our mission.

AISI's Finance Manager will lead the organisation's finance function. This role will be critical in delivering outstanding outcomes across all aspects of financial management, matching industry standards. We are seeking an experienced finance professional who can shape the team and define efficient processes, while delivering expert financial advice to AISI's senior leaders and wider DSIT finance professionals. This role is right for you if you are excited about building a team and reputation for excellence in AISI's unique operating environment. You will have exposure to senior staff in AISI, technical leaders across AISI's research unit and finance professionals in DSIT.

In leading AISI's finance team, we expect you to:

• Exert strong organisational grip over AISI's financial position and manage our finance data including expenditure and forecast tracking.
• Advise senior leaders on business planning decisions using financial insights.
• Own our 'procure to pay' pathway, ensuring great supplier satisfaction through on time payments.
• Build out smarter and more efficient systems, working with DSIT and AISI's operations specialists.
• Build strong relationships with DSIT's central finance team to make improvements to systems and ways of working, while contributing to department-wide financial information to support AISI's operational and strategic needs.

This is a huge opportunity to shape one of AISI's key operational pillars, helping drive up efficiency and service excellence across the organisation in pursuit of our mission.

What you’ll be doing:

• Build, maintain and improve clear financial data flows between AISI systems, Oracle & forecast modelling tools, shared service providers, and other trackers.
• Manage a small team of finance professionals who are triaging, raising, receipting payments within AISI.
• Ensure purchase to pay processes — including raising, uplifting, and tracking — are efficient, traceable, and correctly integrated in our systems.
• Improve how expenditure is recorded and reconciled, reducing manual intervention and ensuring month-end data is complete and accurate.
• Define and implement consistent data standards (e.g., cost centres, programme codes, contract dates, and identifiers).
• Develop actionable, reliable reporting tools that provide senior leaders with accurate in-year financial information and forward-looking forecasts.
• Lead meetings with senior staff to deliver efficient decisions on business-critical areas, including troubleshooting finance issues, reprioritising spend in-year and allocating future year budgets through business planning.
• Design or support solutions that enable teams to see spend, pipeline and commitments in one place.
• Work with Finance Business Partners to improve the forecasting process and reduce reliance on manual Excel workarounds.
• Identify automation opportunities to streamline recurring finance processes.
• Document workflows and ensure knowledge transfer so systems are understood beyond individual users.
• Provide training and clear guidance so finance and delivery teams use systems consistently and effectively.
• Collaborate with central DSIT finance and digital teams to ensure alignment on reporting standards and controls.
