Job Title: Cyber Security Operations Lead

Reporting to: Head of Cyber Security, Risk & Compliance

Location: Sydney (CBD / Hybrid)

Role Type: Permanent, Hands-on Technical Lead

Role Overview

Reporting directly to the Head of Cyber Security, you will be the operational "engine room" for a major NSW critical infrastructure provider. This is a hands-on, generalist role responsible for maintaining a robust security posture across a modern Microsoft-centric environment. You will act as the bridge between technical security tools, internal development teams, and external service providers (MSSPs).

Key Responsibilities

  • Generalist Defense: Manage and tune additional security layers, including Proofpoint for email security and various Microsoft security modules.
  • Vulnerability Management: Take ownership of the vulnerability lifecycle. You will identify risks, coordinate with Developers and IT teams to prioritize patching, and ensure that security is integrated into the development process.
  • Vendor & MSSP Management: Act as the primary point of contact for the Managed Security Service Provider (MSSP). You will ensure they are delivering high-quality monitoring and that the organization is getting full value from their services.
  • Governance & Policy: Assist the Head of Cyber in maintaining and updating security policies and standards. You will ensure that technical configurations (like those in Entra ID) actually reflect the written governance and compliance requirements.
  • Incident Support: While not a dedicated IR role, you will be the first point of escalation for security incidents, coordinating response efforts and providing technical guidance during remediation.
  • Third-Party & MSSP Oversight: Manage the technical relationship with the MSSP. You will ensure their performance aligns with the organization's governance standards and that they are meeting their contractual security obligations

Technical Stack & Requirements

  • Microsoft Suite: Deep, hands-on experience with Entra ID (formerly Azure AD) and the broader M365 security ecosystem.
  • EDR/SIEM Exposure: Practical experience navigating CrowdStrike and Splunk to monitor threats and investigate alerts.
  • Vulnerability Management: Proven ability to manage vulnerability tools and, more importantly, influence developers to remediate findings.
  • Stakeholder Management: Comfortable communicating technical risks to developers, MSSP partners, and business stakeholders.
  • Generalist Mindset: You enjoy "wearing many hats"鈥攆rom tweaking email filters in Proofpoint to discussing architectural security with the Head of Cyber.
