Cyber Investigations Manager

We have an exciting opportunity for a hands-on Cyber Investigations Manager to join Downer’s Cyber Defence function. Based in Sydney, this role leads complex cyber investigations, coordinates digital forensic activities and helps strengthen our incident response capability across the enterprise. 

This is a practical leadership role for someone who enjoys investigation work, evidence-led analysis, stakeholder engagement and developing capability in teams. Previous formal people leadership experience is valued, but not essential. We also welcome candidates who have demonstrated mentoring, coaching or technical leadership in cyber security, investigations or digital forensics environments.

Reporting to the Head of Cyber Defence, you will help ensure investigation outcomes are timely, defensible and aligned to business priorities, legal and privacy expectations, and Downer’s cyber security strategy.

About the Role 

In this role you will:

• Lead complex cyber investigations and coordinate digital forensic activities across the organisation.
• Manage investigation activities for escalated cyber security incidents, including determining scope, business impact, root cause, and remediation requirements.
• Ensure evidence is collected, handled, documented, and retained in accordance with agreed procedures and governance requirements.
• Translate technical findings, forensic evidence and security artefacts into clear investigation conclusions and actionable recommendations.
• Coordinate across internal teams and external specialists during sensitive or high-profile investigations.
• Drive lessons learned from investigations into improved security controls, detection capabilities, incident response playbooks and remediation programs.
• Provide leadership, coaching and direction to the Investigation & Forensics Analyst while fostering a culture of continuous improvement and knowledge sharing.
• Manage relationships with security vendors, managed security service providers (MSSPs) and specialist investigation partners to support effective investigation outcomes.
• Deliver stakeholder-ready reporting and communicate sensitive findings appropriately to technical, business and executive audiences.
• Contribute to the ongoing maturity of Downer's cyber defence capability through process enhancement, training, exercises and operational improvements. 

This is a hands-on role where you will combine technical expertise, investigative judgement and clear communication to support sensitive decisions, improve investigation quality and strengthen Downer’s cyber resilience over time.

Our Ideal Candidate

You are a proactive cyber investigator or digital forensics professional who enjoys solving complex problems, working through evidence and helping others build confidence and capability. You can move between technical detail and business context, and you are comfortable communicating sensitive findings with care, clarity and discretion.

You bring sound judgement, strong attention to detail and a collaborative style. You are curious, practical and improvement-focused, with the confidence to lead investigations and the humility to keep learning.
