Downer Professional Services is comprised of two business units, our Technical, Advisory, and Capability consulting practice and Team Downer, a major service partner to Defence. Together, we are a multi-disciplinary advisory and delivery partner of choice for our clients in Defence and National Security.

We currently have an opportunity for a Commercial Lead in Adelaide to join the Space Systems Branch within the Space Domain Awareness System Program Office.

What You’ll Do

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

Lead procurement planning, tendering, contract formation, and ongoing contract management, ensuring compliance with legislation and policy.
Provide accurate and timely advice on procurement policy, legal, financial, and technical matters to support contract outcomes.
Prepare high-quality procurement documentation including reports, submissions, strategies, risk reviews, and contract change proposals.
Engage with clients and stakeholders, manage complex enquiries, and negotiate contract issues with initiative and professionalism.
Apply legal principles and ensure adherence to legislative and policy frameworks, focusing on commercial risk and performance.

What You’ll Bring

Demonstrated experience in commercial, business, or procurement roles within complex organisational environments, with a strong understanding of contract management principles and procurement lifecycle processes.
A track record of successfully leading and managing teams, with the ability to supervise tasking at an APS6 level, foster collaboration, and drive performance in dynamic and multidisciplinary settings.
A sound understanding of Commonwealth procurement policies, legislative frameworks, and Defence-specific governance requirements, with the ability to apply these effectively to ensure compliance and strategic alignment.
Demonstrated critical thinking and problem-solving skills, with the ability to assess complex commercial issues, identify risks, and develop practical and compliant solutions that support business objectives.
Highly developed interpersonal and communication skills, with the ability to engage confidently with internal and external stakeholders, negotiate effectively.

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. In some instances, compliance with International Traffic in Arms Regulations (ITAR) requirements may also be an inherent requirement.

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