Job Requisition ID: 41668

Join a high-impact Secure Networks Operations team where you'll own Palo Alto firewall performance, policy uplift and lifecycle activity across a complex enterprise environment. Tackle big issues like cyber, trust, resilience and digital transformation Mentoring, coaching and leadership programs to help you make an impact that matters

Step into this Senior Consultant opportunity in Sydney, working in a hybrid model on critical firewall operations that help keep enterprise services secure, stable and running smoothly.

What will your typical day look like?

Much of your work will centre on the day-to-day operation and optimisation of Palo Alto Networks firewalls and Panorama. That includes monitoring health, performance and capacity, resolving Level 2 and 3 incidents, and carrying out root cause analysis to address recurring issues. You'll also support upgrades, patching, vulnerability remediation and lifecycle activities in a way that protects platform stability and reduces operational risk.

A key part of the role is strengthening the security posture of the environment through thoughtful policy and rule base management. You'll review and refine firewall policies, remove redundant or overly permissive rules, and help ensure controls align with security standards and governance requirements. Your work will directly support secure connectivity, incident response, audit readiness and resilient network services across the enterprise.

The role brings plenty of variety and collaboration, with close engagement across network operations, cyber security teams, change forums and other technical stakeholders. You'll contribute operational standards, runbooks and best practices, support major incidents and after-hours maintenance where needed, and bring a steady hand to high availability environments, failover testing and centralised policy deployment through Panorama.
