AI Security Engineer (Agentic Systems)

Must Have:

• Hands-on experience red-teaming or adversarially testing LLM or agentic AI systems, including prompt injection, jailbreaking and tool-misuse scenarios
• Practical understanding of how to test non-deterministic systems and how to detect, quantify and mitigate hallucination
• Working knowledge of agentic-AI-specific risk frameworks and taxonomies, such as OWASP's agent risk categories and MITRE ATLAS
• Experience with the OWASP Top 10 for LLM Applications, including prompt injection and system-prompt-leakage risk categories
• Experience designing or applying an AI governance framework (for example NIST's AI Risk Management Framework) to translate identified risks into organisational controls
• Ability to operate across accounts and teams, building test strategy and tooling recommendations that generalise beyond a single application
• Threat modelling and security review experience
• Strong communication skills, able to explain agentic AI risk clearly to technical and non-technical stakeholders, including on what should and shouldn't be released to clients
• Comfortable being hands-on first — implementing and running agentic security tests directly — then mentoring and training other security engineers to take the practice on themselves
• Nice to Have:
• Familiarity with agent-hijacking or agent-specific evaluation tooling (for example open-source agent-security benchmarks)
• Awareness of emerging AI regulation relevant to security testing, such as the EU AI Act's adversarial and robustness-testing requirements
• Experience with multi-agent or agent-mesh systems and the trust/authentication issues between agents
• Cloud security background (Azure preferred) and Terraform and CI/CD
• Experience in a regulated sector (for example financial services)
