Brilliant people trusted to do brilliant things

Mott MacDonald is a vibrant and forward-thinking engineering, management, and development consultancy. Working together as a global team we plan, design, deliver and maintain the transport, energy, water, buildings, defence and wider infrastructure that is integral to people’s daily lives. We value excellence in every dimension of our business and continuously seek opportunities to improve what we do and how we do it.

We employ brilliant people who combine their diverse skills and experiences to achieve brilliant things. Whether you want to specialise or broaden your experience, you'll be supported by global specialists eager to share their expertise. With numerous opportunities to learn and grow, the possibilities are as diverse as our people. Working as a connected global team, we deliver impactful projects that shape the future.

The opportunity

Join our growing Systems Engineering & Integration team in Adelaide and help clients turn complex needs into integrated, assured and operationally ready solutions. We are seeking expressions of interest from systems engineers and professionals with relevant systems experience, from three years’ experience through to senior level. You may already work as a systems engineer, have specialist expertise across part of the systems lifecycle, or apply systems thinking and systems engineering practices within another engineering discipline.

You will have the opportunity to work on complex infrastructure and technology projects across sectors including water, energy, transport, defence and the built environment.

Depending on your experience and interests, your work could include requirements management, systems architecture, interface management, integration planning, verification and validation, assurance, testing and commissioning, and operational readiness. At senior and principal levels, you may also lead systems engineering activities, shape project approaches and provide technical advice to clients and multidisciplinary teams.

Our approach brings these activities together through five connected pillars: Realising Requirements, Staged Integration, Holistic Proving, Progressive Assurance and Operational Integration. Together, these help clients maintain alignment from the original need through to an integrated solution that is supported by evidence and ready for operation.

Whether you are developing your systems engineering career or already bring significant experience, there is scope to contribute to complex projects, build your expertise and collaborate with systems specialists across Australia and globally.

About you

  • A degree in engineering, science or another relevant discipline, with demonstrated experience applying systems engineering to complex projects.
