Qualifications

Preferred Skills
Hands-on use of agentic AI tooling and frameworks (API, MCP-based automations, or similar) applied to real IT or security tasks. Experience supporting an ISO 27001-certified environment, or compliance tooling such as Vanta. Exposure to defence, government, or other regulated, high-assurance settings. Scripting and automation (for example shell or Python) for device and account management. Detection and response experience, or familiarity with SIEM, log analysis, and incident handling.
