The AI Security Institute is the world’s largest and best-funded team dedicated to understanding the capabilities and impacts of advanced AI and translating that knowledge into action. We operate at the heart of the UK government with direct links to the Prime Minister’s office and collaborate with frontier developers and governments globally.
About the Team
The Cyber and Autonomous Systems Team (CAST) researches and maps the evolving frontier of AI capabilities, focusing on preventing harms from high-impact cybersecurity capabilities and highly capable autonomous AI systems. Our team blends high-velocity generalists with technical experts from Meta, Amazon, Palantir, DSTL, and Jane Street.
About the Role
We are looking for a cybersecurity engineer to design environments and challenges that benchmark the cyber capabilities of AI systems. You will build cyber ranges, CTF-style tasks, and evaluation infrastructure to measure how well frontier AI models perform on real-world cybersecurity tasks.
Core Responsibilities
- Evaluation Design & Development (60%)
- Design cyber ranges and CTF-style challenges for automatically grading AI system performance on cybersecurity tasks.
- Build agentic scaffolding to evaluate frontier models, equipping them with tools such as network packet capture utilities, penetration testing frameworks, and reverse engineering/disassembly tools.
- Design metrics and interpret results of cyber capability evaluations.
- Infrastructure engineering (30%)
- Work alongside other engineers to ensure evaluation environments are robust and scalable.
- Research & Communication (10%)
- Write reports, research papers, and blog posts to share findings with stakeholders.
- Keep up to date with related research taking place in other organisations.
- Contribute to AISI’s broader understanding of AI cyber risks.
Example Projects
- Onboard and integrate new cyber ranges into our evaluation pipeline.
- Conduct agent research to improve the cyber capabilities of our agents.
- Improve grading and scoring methodologies for automated evaluation tasks.
- Integrate defensive telemetry and simulated users into ranges to increase realism.
- Collaborate with government partners on joint research publications.
Impact
Your work will directly shape the UK government’s understanding of AI cyber capabilities, inform safety standards for frontier AI systems, and contribute to the global effort to develop rigorous evaluation methodologies. The evaluations you build will help determine how advanced AI systems are assessed before deployment.

Use of AI in Applications
Artificial Intelligence can be a useful tool to support your application. All examples and statements provided must be truthful, factually accurate and taken directly from your own experience. Where plagiarism has been identified—presenting ideas and experiences of others or generated by artificial intelligence as your own—applications may be withdrawn and internal candidates may be subject to disciplinary action.
Internal Fraud Database
The Internal Fraud function of the Cabinet Office processes details of civil servants who have been dismissed for committing internal fraud or would have been dismissed had they not resigned. The Cabinet Office bans these individuals for 5 years from further civil service employment. The Cabinet Office then discloses a limited dataset back to the DLUHC. DLUHC carries out pre-employment checks to detect known fraudsters attempting to reapply for roles.
