Security Admin (SM) – Secure Migration & Compliance | Mission Critical Programme

About our client

Our client is delivering a large-scale, mission-critical infrastructure transformation programme of national significance, operating within a highly secure and regulated environment.

This programme is centred on the modernisation of critical systems and platforms, where security, compliance and data protection are foundational – not optional. Every component of the architecture is being designed, built and migrated with Defence-aligned security standards at its core, ensuring resilience, auditability and protection of sensitive information.

The programme spans multiple data centres and involves complex migration waves across compute, network, storage and VDI environments. Within this context, security plays a central role in ensuring systems remain protected, compliant and operationally sound throughout the transformation lifecycle.

About the role

You will be responsible for ensuring that security controls are maintained, enforced and validated throughout the migration lifecycle, working across a complex and evolving infrastructure environment.

This is not a peripheral security role — you will be directly embedded in delivery, ensuring that each migration wave meets strict compliance, audit and security requirements before, during and after transition.

Key responsibilities

- Enforce and validate ACSC Essential Eight, ISM and security baseline controls across infrastructure
- Manage and monitor encryption, access control and audit logging frameworks
- Conduct vulnerability scanning, risk identification and remediation activities
- Support the implementation and validation of network segmentation and micro-segmentation policies
- Ensure security posture is preserved through migration waves, including configuration and policy continuity
- Produce and maintain audit-ready documentation and compliance evidence
- Collaborate with architects, engineers and programme leads to align security with delivery outcomes




- Support security testing, validation and post-migration assurance activities

This role is critical in ensuring the platform is secure by design, compliant by default, and ready for operational deployment.

- Exposure to secure or highly regulated environments (Defence or Federal preferred)
- Strong understanding of security controls within infrastructure and migration contexts
- Detail-oriented with a focus on compliance, audit and risk management
- Ability to operate effectively within fast-paced, multi-workstream delivery environments

Mandatory requirement

- NV2 clearance preferred, OR NV1 with NV2 actively in progress (non-negotiable)

What is on offer?

- $170,000 + super + performance bonus
- Opportunity to work on a mission-critical programme supporting nationally significant systems and data
- Be part of an environment where security is embedded at every layer of design and delivery
- Long-term programme (initial 2-year engagement with strong extension potential)
- Melbourne or Adelaide preferred, with flexibility for FIFO arrangements across Australia
- Work alongside high-performing security, architecture and engineering teams

Why this opportunity stands out

Security here is not treated as a control function — it is a core pillar of programme success.

You will be working in an setting where standards are uncompromising, systems are critical, and the stakes are high — ensuring that infrastructure supporting national capability is secure, compliant and resilient.

If you’re looking for a role where your expertise in security has real impact, real visibility and real importance, this is a standout opportunity.
