Staff Threat Detection

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.

About The Team
Security Engineering at the AI Security Institute (AISI) exists to help our researchers move fast, safely. We are founding the Security Engineering team in a largely greenfield cloud environment, we treat security as a measurable, researcher centric product.

Secure by design platforms, automated governance, and intelligence led detection that protects our people, partners, models, and data. We work shoulder to shoulder with research units and core technology teams, and we optimise for enablement over gatekeeping, proportionate controls, low ego, and high ownership.

What You Might Work On

• Help design and ship paved roads and secure defaults across our platform so researchers can build quickly and safely
• Build provenance and integrity into the software supply chain (signing, attestation, artefact verification, reproducibility)
• Support strengthened identity, segmentation, secrets, and key management to create a defensible foundation for evaluations at scale
• Develop automated, evidence driven assurance mapped to relevant standards, reducing audit toil and improving signal
• Create detections and response playbooks tailored to model evaluations and research workflows, and run exercises to validate them
• Threat model new evaluation pipelines with research and core technology teams, fixing classes of issues at the platform layer
• Assess third party services and hardware/software supply chains; introduce lightweight controls that raise the bar
• Contribute to open standards and open source, and share lessons with the broader community where appropriate

If you want to build security that accelerates frontier scale AI safety research, and see your work land in production quickly, this is a good place to do it

Role Summary

Build and maintain a modern, mission-aware detection engineering practice. You'll own AISI's threat model, define detections that reflect AISI-specific risks, and collaborate with DSIT's SOC to extend coverage and context. You'll focus on signal quality, not alert volume. You will extend coverage to AI/ML surfaces, instrumenting the model lifecycle and AI platforms so threats to model weights, data pipelines, GPU estates, and inference endpoints are visible, correlated, and actionable.

Responsibilities

• Define and evolve AISI's threat model, working with platform, research, and policy teams
• Write detection rules, correlation logic, and hunt queries tailored to AISI's risk surface
• Ensure relevant signals are logged, routed, and contextualised appropriately
• Maintain detection playbooks, triage documentation, and escalation workflows
• Act as a liaison between AISI engineering and DSIT's central SOC
• Evaluate detection gaps and propose new signal sources or telemetry improvements
• Extend the threat model to AI/ML: data/feature pipelines, training/finetuning, evaluations/release gates, registries, GPUs, and inference services
• Develop detections for AI-specific risks: model weight custody/exfil (e.g., anomalous KMS decrypts, S3 access), registry tampering, dataset poisoning, training pipeline/image compromise, GPU abuse/cryptomining, and inference abuse (prompt injection/data exfil patterns, anomalous RAG connector access)
• Integrate AI platform telemetry (e.g., SageMaker/Bedrock logs, model registry events, provenance/attestation)
• Define hunts and correlations that tie AI safety/evaluation signals (red-team hits, eval regressions, release gate overrides) to security events and insider/outsider activity
• Author and rehearse AI-focused incident playbooks (weights leak, compromised model artefacts, inference abuse campaigns) with DSIT SOC

Profile Requirements

• Strong understanding of detection-as-code, MITRE ATT&CK, log pipelines, and cloud signal sources
• Able to navigate outsourced SOC relationships while owning internal threat understanding
• Familiarity with AWS CloudTrail, GuardDuty, KMS, S3 access logs, EKS/ECS audit, custom log ingestion; exposure to SageMaker/Bedrock or equivalent a plus
• Curious, methodical, and proactive mindset
• Practical grasp of AI/ML attack surfaces and telemetry needs (model registries, weights custody, GPU/accelerator fleets, inference gateways, vector stores)
• Familiarity with AI threat frameworks (e.g., MITRE ATLAS, OWASP Top 10 for LLMs) desirable

Key Competencies

• Detection engineering mindset focused on signal quality and measurable coverage
• Familiarity with MITRE ATT&CK and detection pipelines
• Understanding of cloud-native telemetry and logging gaps
• Ability to collaborate with outsourced SOCs
• Instrumenting and detecting threats across AI/ML workloads (weights, datasets, training/inference) and correlating safety and security signals

Additional Information

Internal Fraud Database
The Internal Fraud function of the Fraud, Error, Debt and Grants Function at the Cabinet Office processes details of civil servants who have been dismissed for committing internal fraud, or who would have been dismissed had they not resigned. The Cabinet Office receives the details from participating government organisations of civil servants who have been dismissed, or who would have been dismissed had they not resigned, for internal fraud. In instances such as this, civil servants are then banned for 5 years from further employment in the civil service. The Cabinet Office then processes this data and discloses a limited dataset back to DLUHC as a participating government organisations. DLUHC then carry out the pre employment checks so as to detect instances where known fraudsters are attempting to reapply for roles in the civil service. In this way, the policy is ensured and the repetition of internal fraud is prevented. For more information please see - Internal Fraud Register.

Security

Successful candidates must undergo a criminal record check and get baseline personnel security standard (BPSS) clearance before they can be appointed. Additionally, there is a strong preference for eligibility for counter-terrorist check (CTC) clearance. Some roles may require higher levels of clearance, and we will state this by exception in the job advertisement. See our vetting charter here.

Nationality requirements

We may be able to offer roles to applicant from
any nationality or background
. As such we encourage you to apply even if you do not meet the standard nationality requirements (opens in a new window).

Working for the Civil Service

The Civil Service Code (opens in a new window) sets out the standards of behaviour expected of civil servants. We recruit by merit on the basis of fair and open competition, as outlined in the Civil Service Commission's recruitment principles (opens in a new window). The Civil Service embraces diversity and promotes equal opportunities. As such, we run a Disability Confident Scheme (DCS) for candidates with disabilities who meet the minimum selection criteria. The Civil Service also offers a Redeployment Interview Scheme to civil servants who are at risk of redundancy, and who meet the minimum requirements for the advertised vacancy.
