THE ROLE
Building on the successes of AI for Cyber Defence (AICD) Research Centre, the Defence & National Security (D&NS) team at the Alan Turing Institute is developing an ambitious programme of research to deliver a fundamental shift in Critical National Infrastructure (CNI) cyber-resilience using AI. The focus of this new programme is the cyber resilience of CNI, including legacy operational technology (OT) and end-of-life operating systems; both of which underpin critical sectors from energy and water to data operations, but that cannot be patched, upgraded, or modified without risking operational disruption or invalidating safety certification. This role will sit within the D&NS team and focus on advancing resilience of CNI by designing, building, and evaluating LLM-driven agentic systems for the autonomous hardening of legacy operational technology and industrial control systems.
ABOUT YOU
The ideal candidate will have experience integrating with LLM APIs and building agentic or tool-calling pipelines to implement multi-step reasoning workflows (e.g. MCP, LangGraph). You’ll use your knowledge from a master’s degree (or equivalent experience), utilising a range of methodologies to tackle problems set by the partner. You’ll need a understanding network security principles e.g. defensive and offensive security, this will be teamed with the work you do when you plan and run AI-based CNI red-blue teaming competitions. All of your experience will be needed when you develop realistic virtualised environments with legacy OT/ICS hosts, having experience of this is key to move the project forward.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Publishing our outputs is key to the role, so you would have a track record of first authorised or contributed heavily to previous publications so you can hit the ground running – this is also where your excellent verbal and written communication skills come in.
HOW YOU WILL MAKE AN IMPACT
- Collaboratively design, build and maintain agentic, AI systems and evaluation suites that support CNI cyber resilience and legacy software hardening against known vulnerabilities.
- Develop virtualisation based digital twin environments and implement techniques for assuring operational continuity in the context of CNI.
- Develop CNI-relevant scenarios with clear threat models, operational continuity criteria, and defensible assumptions; document limitations and known failure modes explicitly.
- Run large-scale evaluations on HPC and cloud platforms, improving performance and reliability through batching/parallelisation, resource-aware execution, and systematic debugging of non-determinism and environment drift.
- Play a role in planning and running AI-based CNI red-blue teaming competitions, ensuring robust environment design and evaluation protocols are in place.
