About the Role

Our client is a leading digital intelligence organisation with experts across multiple countries, working with governments, armed forces, and commercial organisations to unlock digital advantage in the most demanding environments.

We’re seeking a Senior Security Consultant (AI) to join their National Security AI team in London. This is a hands‑on, strategic role where you’ll help clients secure AI/ML systems, advise on emerging AI threats, and design resilient architectures across cloud and hybrid environments. You’ll play a direct role in pioneering AI adoption for national security, delivering solutions that make a tangible impact on the UK’s security.

What You’ll Be Doing

• Conduct security assessments, threat modelling, and risk analysis across cloud, on‑premises, and hybrid environments.
• Evaluate and secure AI/ML systems, including model governance, data pipelines, and deployment patterns.
• Advise on AI risk management: prompt injection, model poisoning, data leakage, privacy risks, and adversarial attacks.
• Design and recommend secure architectures for AI‑enabled applications, including LLM‑based systems and decision‑support platforms.
• Develop security policies, standards, and guidelines, particularly around AI governance and responsible AI use.
• Collaborate with engineering teams to implement secure configurations, guardrails, and controls.
• Stay ahead of emerging threats and best practices in cybersecurity and AI safety.

Ideal Background

• Proven experience in cybersecurity consulting, architecture, or engineering roles.
• Strong understanding of security fundamentals: IAM, network security, encryption, vulnerability management, and incident response.
• Hands‑on experience securing AI/ML systems, LLMs, or data science pipelines.
• Knowledge of modern attack techniques including AI‑assisted attacks, adversarial ML, and supply‑chain risks.
• Familiarity with cloud security frameworks (AWS, Azure, GCP) and industry standards (NIST, ISO 27001, OWASP, MITRE ATLAS).
• Excellent communication and client‑facing skills, able to translate technical concepts for non‑technical stakeholders.
• CISSP, CCSP, OSCP, CEH, GIAC, or cloud security certifications.
• Experience with AI model evaluation, fine‑tuning, RAG pipelines, or vector databases.
• Knowledge of AI ethics, governance, and regulatory frameworks (EU AI Act, NIST AI RMF, ISO/IEC 42001).
• Familiarity with DevSecOps, automation, IaC, and security control integrations.

Security Clearance: Required. Candidates must be eligible for SC/DV clearance.

What You’ll Receive

• Flexible working hours and hybrid working options (3 days in London office per week).
• 25 days annual leave with option to buy/sell/carry over.
• Flexible benefits: private medical and dental insurance, pension, cycle‑to‑work scheme, Tastecard, and more.
• Dedicated Career Manager for personal development and progression.
• Company bonus scheme and Diversity & Inclusion groups.

Who Should Apply

This role suits highly skilled cyber security professionals with experience in AI/ML security, who want to make a direct impact on national security. You’ll thrive in a collaborative, innovative environment with opportunities to develop across multiple disciplines.
