AI Security Engineer (Agentic Systems)

ClearRoute is an engineering consultancy bridging Quality Engineering, Cloud Platforms and Developer Experience. We help enterprises reliably bring high-impact digital products to market faster, cheaper, and safer, working with technology leaders facing complex business challenges.

We take as much pride in our people, culture and work-life balance as we do in making better software. We’re not just making better software. We’re making the making of software better. Collaborative, entrepreneurial and dedicated to problem solving, we bring the step change our customer need to sustain innovation. Our values challenge us to do the best we can for ClearRoute, our customers and most importantly our team. This is an opportunity for you to build the organisation from the ground up, use your voice to drive change and help transform organisations and problem domains.

Role

This role sits apart from our traditional cloud security engineering positions: it is centred on AI and agentic systems rather than infrastructure alone. You will test and secure AI use cases across an account, not a single application or user set, building a broad, first-hand picture of how ClearRoute should approach testing, risk and governance for agentic AI.

You will work across teams rather than within one delivery stream, owning the question of what «good» looks like for agentic security testing across the account, and helping ClearRoute build a repeatable, defensible approach that other engagements can adopt.

The role is deliberately hands-on in its first phase: you will implement and run the testing yourself, so you understand the detail before asking anyone else to follow it. As that practice matures, the role shifts toward governance across the account, training and upskilling existing security engineers to implement and automate the strategy themselves, so agentic security testing becomes something the wider team can run, not something that depends on one person.

Agentic Red Teaming & Adversarial Testing:

Agentic Governance & Risk:

Cross-Team & Organisational Scope:

• 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
• 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)
