Security Lead

Fractional (1–2 days/week) – 3 month rolling contract

Hybrid- London

We’re hiring for a forward-thinking security leader to help shape and secure an AI-first organisation.

This is not a traditional CISO role. We’re looking for someone more hands‑on, technical, and AI‑native, a builder who can define and implement a modern AI security posture over the next 12–24 months.

What you’ll be doing

• Defining and implementing AI security strategy and guardrails across the business
• Securing adoption of LLMs, copilots, and AI tools across engineering and non-technical teams
• Designing data access controls and policies for AI systems
• Building strategies around prompt security, data leakage, and model risk
• Assessing and managing third‑party AI vendor risk
• Establishing model governance, auditability, and best practices
• Supporting a shift towards an AI‑first product and operating model

What we’re looking for

• Experience in AI security, AI architecture, or security engineering with an AI focus
• Hands‑on experience working with LLMs, GenAI tools, and AI‑enabled systems
• Proven ability to build and implement AI security frameworks (not just advise)
• Strong understanding of data security, access control, and risk in AI environments
• Pragmatic, delivery-focused mindset—comfortable operating in fast-moving environments

This role is not

• Purely compliance-focused (ISO, SOC, etc.)
• Advisory-only — we need someone who can build and implement

If you’re working at the intersection of AI + security and want to help shape how organisations securely adopt AI in practice, this is a unique opportunity.
