Senior Security Engineer

  • Western Sydney location

  • Hybrid working model

  • Permanent role

If you're looking for a standard security ops role where you're monitoring dashboards and closing tickets, this probably isn't it. If you're the person your team turns to when a high-priority incident hits, when the firewall architecture needs a rethink, or when the business needs someone who genuinely understands the intersection of IT and OT security...keep reading.

 

We're partnering with a large, well-established Australian utilities organisation that operates at serious scale and serves millions of customers every day, an essential service that operates 24/7 and serves millions of people every day. They're investing seriously in the maturity of their security operations capability, and this is a hands-on senior role at the heart of that effort.

 

You'll be working across network and perimeter security, incident response, threat analysis and continuous improvement - influencing security strategy, mentoring junior engineers and acting as a genuine technical authority within the team.

Key Responsibilities

What you'll be doing

You'll operate across both engineering and security operations, including:

  • Assessing and strengthening security controls across IT and Operational Technology (OT) environments

  • Optimising and maintaining firewalls, load balancers, web proxies, VPNs and vulnerability management platforms

  • Leading and coordinating responses to high-priority security incidents and representing Security Ops in incident management forums

  • Driving continuous improvement initiatives to reduce organisational risk and improve cyber resilience

  • Configuring and enhancing network segmentation, web application firewalls and SASE/SSE/SD-WAN technologies

  • Conducting analysis of significant security events and working with threat hunting and cyber defence teams

  • Partnering with IT, OT, infrastructure and project teams to embed security requirements into solutions

  • Supporting compliance with ISO 27001 and other relevant regulatory frameworks

  • Providing Level 2 and Level 3 support for security incidents, problems and changes

  • Mentoring junior engineers and acting as an escalation point when needed

Requirements

​

 This role isn't about ticking certification boxes. We're looking for someone who has           genuinely operated enterprise-grade security environments at scale and can speak confidently to the decisions they've made and why.

​

   Ideally you'll bring hands-on experience with:

  • Network and perimeter security technologies at enterprise scale

  • Palo Alto and Check Point firewalls

  • VMware NSX Firewall and AVI Load Balancer

  • Secure Web Gateways, web proxy solutions and Azure WAF

  • SSE and SD-WAN / SASE technologies

  • Vulnerability management platforms

  • Incident response in complex enterprise environments

  • ISO 27001 security controls and governance frameworks

  • Desirable but not essential:

  • Experience in OT environments or critical infrastructure

  • Vendor certifications across Palo Alto, F5, VMware NSX, Netskope, Zscaler or Forcepoint

  • CISSP certification

  • Knowledge of the Australian Energy Sector Cyber Security Framework (AESCSF)

​

You'll likely come from a senior security engineering or security operations background within a large enterprise or utilities/critical infrastructure environment. You're technically credible, calm under pressure and equally comfortable leading an incident response as you are presenting recommendations to senior stakeholders.

Nice to Have

​

  • General risk management knowledge.

  • Background inn risk and insurance

  • Experience working on large transformation or modernisation programs.

We are super excited to hear from you, learn more about you and tell you more about us. So hit APPLY now and let's catch-up.
