What You Will Do

• Define workplace security strategy, target/reference architectures, and technical standards.
• Drive Zero Trust adoption across workforce identity, endpoints, messaging, and collaboration.
• Provide authoritative security design decisions and assurance for workplace technology changes.
• Own and maintain the multi-year security roadmap and investment priorities.
• Partner with platform engineering teams to embed secure-by-design principles into delivery pipelines.
• Mentor senior engineers and set the standard for engineering quality.

• Demonstrated leadership: Proven experience defining workplace security strategy and leading complex security transformations in a large organisation.
• Deep Architectural Knowledge: Microsoft Entra ID, Defender suite, Microsoft 365, Exchange Online, Teams, Conditional Access, and Intune.
• Executive Communication: Ability to translate technical risk into clear business context for senior executives.
• Australian work rights and willingness to travel to Singapore occasionally.

Nice to Have

• Jamf experience
• Security-as-code and automated compliance guardrails
• Certifications: SC-100, CISSP, ISSAP, or SABSA

Note: This may not be the right role if you have been a senior engineer but have not yet held formal architecture or design authority responsibilities.

Remuneration

• Daily Rate: $800 – $1,000 per day (depending on experience)

How to Apply

Please submit your resume along with brief answers (a few lines each) to the following three questions:

• Describe a workplace security architecture or Zero Trust programme you led, and its scale.
• What decision did you make as design authority that others disagreed with, and what happened?
