Chapter Lead (Senior Manager) Network Security Controls

• Are you a network security SME looking for a broad leadership role?
• Enthusiastic about working with cutting-edge technology to defend against cyber threats?
• Understand the importance of policy setting and control assurance to deliver security outcomes at scale?

This role might be your next step.

• You are a cybersecurity risk and control leader with deep network security expertise and a track record of leading high-performing teams.
• We are one of the best and most advanced Cyber Security teams in Australia.
• Together we can build the Cyber Controls Chapter Area and contribute to protecting the Group, its customers and community.

See yourself in our team:

The Cyber Controls Chapter Area plays a crucial GRC function within the Group Security division. It is responsible for defining and implementing effective cyber control capabilities and overseeing continuous improvement of the Group's cyber risk profile.

As an organisation with a large IT estate servicing millions of customers every day, we need to ensure effective mitigations are in place to defend our assets against an ever-evolving cyber threat environment. The Chapter Lead Network Security Controls oversees a team of network security SMEs. The team defines the Group's network security policy, works with Technology Crew Leads to implement network security capabilities, and monitors control compliance. Your portfolio will include Network Segmentation, Secure Internet Access, Network Threat Detection & Protection, DDoS and Secure Remote Access, as well as the Zero Trust network security program.

We support our people with the flexibility to balance where work is done with at least half your time each month connecting in office. We also have many other flexible working options available including changing start and finish times, part-time arrangements and job share to name a few. Talk to us about how these arrangements might work for you.

Do work that matters

Working with the Cyber Controls Chapter Area Lead and collaborating with peers, you will:

• Lead, coach and develop a team of Control Managers and Analysts, setting priorities and directing capacity toward the highest risk and growth areas.
• Help define and deliver the network security strategy and roadmap together with Technology Crew Leads and Product Owners.
• Establish and maintain network security standards, requirements and design/operating-effectiveness criteria in line with industry standards, technology strategy and threat intelligence.
• Govern the Group's compliance with network security control requirements in line with the Group Operational Risk Management Framework.

You will also:

• Monitor threat controls: assess IPS/IDS signature-blocking activity and maintain performance dashboards to support day-to-day triage and monitoring by Cyber Defence Operations.
• Partner with engineering: embed requirements across Cloudflare, Corelight, Palo Alto/GlobalProtect, Network Access Control and firewall environments.
• Measure and report effectiveness: keep control health, coverage and compliance metrics and evidence up to date, and support monthly governance reporting, Control Self-Assessments and independent control testing.
• Drive remediation: find weaknesses such as overly permissive firewall rules, segmentation gaps, exposed public endpoints and remote-access issues, raise issues, and hold service owners and engineering teams to remediation.
• Govern exceptions: provide front-door control advice, assess proposed deviations and make sure exceptions go through the required risk assessment and endorsement.
• Deliver strategic uplift: ensure enforcement of deny rules, end-of-life (EOL) lockdown, cloud/on-premises isolation capabilities and control automation.

We are interested in hearing from people who:

• Embody the leadership principle of 'Curious and Humble' by being willing to speak up and challenge the status quo, and continually expanding their skills and knowledge.
• Have led and developed teams of control or security professionals, and can balance operational upkeep with strategic delivery.
• Have deep knowledge of network security architecture, Zero Trust principles and current network threats.
• Have experience with segmentation, firewall, secure web gateway, NIDS/NIPS, DDoS, WAF/WAAP and remote access solutions in large, complex IT environments.
• Can analyse threat intelligence, identify potential risks and recommend appropriate mitigations.
• Can operate effectively in an agile working environment, showing high autonomy and self-initiative to achieve target outcomes.
• Can engage and influence senior stakeholders to build rapport, obtain buy-in and achieve target outcomes.

Technical skills that will benefit you in the role:

• Applied knowledge of ASD ISM, Essential Eight, NIST CSF, NIST SP 800-207 (Zero Trust) and CIS Controls, and how to turn them into control standards and design/operating-effectiveness criteria.
• Hands-on familiarity with network security platforms such as Palo Alto (PRISMA, GlobalProtect), Cloudflare, Corelight/Zeek, Suricata and NAC solutions.
• Experience with microsegmentation, firewall rule governance and identifying overly permissive or unused flows.
• Understanding of IDS/IPS signature management, blocking-mode tuning and network threat telemetry.
• Experience in control assurance under an operational risk framework, including control testing, Control Self-Assessments, issue and exception management.
• Exposure to control automation, such as scripted compliance checks, API-driven evidence collection or policy-as-code.
• Security certifications such as CISSP, CISM or CRISC.
