Join our Downer Professional Services team and play a key role in delivering complex defence and national security projects that safeguard Australia's future.

This role offers a broad scope, with key role responsibilities including:

• Develop and deliver security documentation such as Security Risk Management Plans, System Security Plans, and Incident Response Plans.
• Provide advisory services on information security to assigned ICT programs and projects.
• Audit and review system security measures, policies, and procedures for compliance and effectiveness.
• Identify and evaluate security risks, vulnerabilities, and requirements to support mission systems.
• Ensure system compliance with ASD's ISM and AGD's PSPF standards and guidelines.

• Experience with Defence systems, applications, and project environments.
• Strong understanding of modern networking, operating systems, and cyber risk management.
• Proven ability to manage relationships across technical and operational security teams.
• Effective communication and collaboration skills within small team environments.

Due to the nature of the work, you are required to currently hold and maintain a minimum Negative Vetting 1 or higher Security clearance as required by the Commonwealth.

More than anything, you'll bring a strong work ethic, a positive attitude, and a commitment to delivering high-quality outcomes for our clients.
