• Conduct threat modelling and risk assessments, define remediation strategies, and explore responsible AI and automation to improve the efficiency and quality of security analysis while maintaining human review

• Guide DevSecOps adoption by designing embedded security and controls within the SDLC, including appropriate guardrails, audit trails and escalation pathways for AI-enabled workflows

• Champion security awareness and mentor teams across engineering, architecture and delivery, encouraging responsible experimentation with approved AI tools where they can improve productivity and outcomes

• Experience designing solutions using Palo Alto, Microsoft or similar security ecosystems

• Deep knowledge of security frameworks and standards, such as NIST, ISO 27001, CAF and TOGAF, combined with experience designing Zero Trust Architecture solutions

• Expertise across IAM, endpoint protection, application and network security, with the ability to translate complex security concepts for technical and non-technical audiences

• Hands-on experience with security tooling such as SIEM, firewalls and IAM solutions
