McMahon Services is looking for an experienced WHSEQ Advisor to join our Building & Construction team in Adelaide.

This is a hands-on operational role supporting the delivery of commercial and Defence construction projects across South Australia, working closely with Project Managers, Site Managers, Engineers, Supervisors and subcontractors.

You’ll need to be proactive, practical and confident thinking on your feet. If you’re someone who can identify an issue, work with the team and find a sensible solution while maintaining strong WHSEQ standards, we’d like to hear from you.

McMahon Services is one of Australia’s largest privately owned construction, industrial and environmental services organisations, employing more than 1,300 people across Australia.

Our Building & Construction team delivers projects across commercial, Defence, government, health, education and community infrastructure, supported by experienced construction and project delivery professionals.
