What they need


We are seeking skilled, driven and passionate people to join our growing team for an exciting and rewarding career.

  • Competitive rates and conditions
  • Career growth and professional development
  • Opportunity to join a growing Australian business

Who We Are – ONECORE

An industry leading project management, engineering, and construction business, we have worked on some of Australia’s largest projects. Having identified a niche within our key markets for our unique set of skills within project management, project delivery and project controls, we have grown at an exponential rate and understand that our ability to grow and be successful depends on our ability to attract and recruit like-minded individuals who want to be part of our journey.

We embrace different. We empower our people, provide them with the tools, knowledge and support and let them get on with their job. We encourage flexibility, focusing on the output and adding value rather than the time in the office.

Our ability to work collaboratively with our clients positions us as a partner of choice – whether it be consulting, project delivery or overall project management solutions, we approach each project differently and are prepared to challenge the norm; a value add we provide to our clients and the creative challenges for our people.

With an ever increasing number of clients and projects we recognise the need for considered planning, steady growth, and that having the right people supported by developing our in-house systems, leveraging technology and being efficient with our processes is critical to our growth.
