  • Publish and present reference architectures and technical solutions to design authorities and senior stakeholders.
Governance

  • Ensure appropriate peer review and documentation quality control.
Risk & Dependency Management
  • Identify, track, and communicate technical risks, design issues, and dependencies.
  • Provide clear, actionable remediation strategies.
  • Map design decisions to residual risks and articulate business/technical trade‑offs.
Cybersecurity & Application Security
  • Hands‑on experience securing modern application architectures (microservices, containerised/K8s environments, cloud‑native systems).
  • Strong background in application security testing (AST) including SAST, DAST, IAST, MAST, and container/K8s scanning.
  • Expertise with Software Composition Analysis (SCA) tools and supply‑chain security.
  • Skilled in building and optimising CI/CD‑integrated security pipelines (GitHub Actions, GitLab, Jenkins, Azure DevOps, etc.).
  • Strong threat‑modelling capability and deep understanding of secure SDLC.
  • Ability to evaluate, design, and integrate enterprise AppSec platforms including SCA/AST tooling, SBOM solutions, and vulnerability workflows.
  • Experience guiding engineering teams through vulnerability remediation and secure coding best practices.
  • Familiarity with industry frameworks such as OWASP SAMM, ASVS, CSA, NIST SSDF, SLSA.
What We’re Looking For
  • A confident communicator capable of presenting deep technical content to both engineers and senior leadership.
  • Someone who brings strong documentation discipline and architectural rigour.
  • A collaborator with broad IT knowledge and the ability to work effectively with non‑security SMEs.
  • A technical leader who can represent Cyber Services at governance boards and design authorities.
  • Experience in both operational and transformation security environments is highly desirable.
