- Transmission & Distribution Join AECOM as a Principal Primary Engineer, where you will lead the design and delivery of high-voltage primary and substation projects while providing technical leadership, mentoring, and support across an established team of engineers and technical specialists. This role provides the opportunity to further develop your career within a collaborative Energy team delivering projects across Australia and New Zealand (ANZ), leveraging your expertise in primary systems and substation design. You will lead projects from concept through to completion, overseeing technical delivery, design outcomes, and project execution while supporting the development of team members. Drawing on your experience delivering high-voltage projects and applying relevant state-based standards and regulations, you will provide technical direction on projects ranging from 330kV to 500kV infrastructure. A key focus of the role will be ensuring the delivery of secure, high-quality, compliant, and efficient substation solutions. You will apply your deep understanding of primary design principles while considering the broader project context, including grid connection requirements and multidisciplinary interfaces. Working across a diverse portfolio, you will contribute to major transmission and energy infrastructure projects, including grid-scale developments, renewable energy connections, and Battery Energy Storage System (BESS) projects.



This is an opportunity to guide complex project delivery, influence technical standards and best practices, and make a meaningful impact on the energy transition across ANZ. How you’ll make a difference:
- Lead the development and review of primary system designs including layouts, equipment selection, earthing systems, and related design requirements.
