Workstream Lead, Agentic AI Risk Modelling and Mitigations

About the 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 (the Prime Minister's office), 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. The deadline for applying to this role is Tuesday 13th October 2026, end of day, anywhere on Earth. Job summary Within AISI’s Research Unit, the Agentic AI Risk Modelling and Mitigations team studies how advanced AI systems could become difficult to oversee, correct or shut down as they take on longer and more autonomous tasks. The team builds scenario-based risk models that extend published work on AI timelines and systemic risk and uses them to identify practical mitigations such as monitoring infrastructure, deployment guidance and containment protocols. Its analysis has been shared across government and is intended to inform real decisions by the organisations best placed to act. We are looking for a Workstream Lead to lead and line-manage this team through its next phase. You will shape the team’s strategy and research agenda, set the scientific direction of its work, and ensure that promising mitigations move from analysis into adoption. This is a senior leadership role for someone who can combine technical judgement, strategic thinking, delivery focus and strong people leadership in a fast-moving and highly consequential area. This role sits within AISI’s Research Unit and reports to a Research Unit Deputy Director. Job description As Workstream Lead for Agentic AI Risk Modelling and Mitigations, you will provide the scientific, strategic and managerial leadership needed to keep the team at the forefront of this area. You will be accountable for the team’s research agenda and for the routes to implementation of any mitigations it identifies. This includes setting priorities, choosing analytical approaches, reviewing the quality of outputs, and ensuring the work is relevant to the institutions that can act on it. You will also lead and develop a multidisciplinary team, oversee multiple strands of work at once, and build strong relationships with senior policy and technical stakeholders across government, research organisations and frontier AI companies. The team’s aim for March 2027 is for the UK organisations best placed to act to have adopted its existing mitigations, and for newly identified mitigations to move more quickly from research to adoption. You will play a central role in achieving that aim. Role summary You will:

• Set the team’s strategy, quarterly plan and overall research agenda;
• Lead the scientific direction of the team’s risk modelling, including selecting approaches, choosing which scenarios to develop, and reviewing outputs;
• Develop analyses of how advanced AI systems could become difficult to oversee, correct or shut down, and identify practical ways to reduce those risks;
