Who Are CPP? 

CPP is a leading high-voltage infrastructure provider, connecting renewable energy projects to Australia’s electricity grid.

As a member of Quanta Services, a Fortune 500 company, and ranked #192 on the NYSX, we specialise in the design, construction, commissioning, and maintenance of substations, transmission lines, wind farms, and battery storage systems.

Established in 1996, we’ve connected more wind farms and renewable batteries than any other company. With over 700 employees and offices in Adelaide, Melbourne, Sydney, and Brisbane, we partner with Australia’s major transmission providers to deliver innovative, end-to-end solutions.

We’re excited to be growing our engineering capability in Perth with the opening of our first office in Western Australia. This is a significant milestone in our growth, creating new opportunities for engineers in WA to be part of our national team while contributing to the next chapter of CPP’s success. Our Perth office will become an important hub in our network, and we’re looking for talented engineers to play a key role in growing this new location from the ground up.

Design & Engineering

CPP has the largest in-house design and engineering team of any contractor in Australia, with over 170 specialists across Electrical Primary and Secondary, Civil, Structural, and SCADA disciplines. We provide end-to-end engineering solutions for high-voltage infrastructure, including nationally significant transmission projects, HV substations, wind farms and battery storage systems that drive Australia’s renewable energy transition.

Our engineers work closely with construction and operations teams, ensuring designs are practical, constructible, and continually refined through real-world feedback. With a commitment to innovation and excellence, we deliver solutions that support a stable, reliable, and sustainable energy future.

The Opportunity 

Step into a career-defining role as Senior Primary Engineer at CPP, where you will play a key role in delivering high-voltage substation projects that support the growth of Australia’s renewable energy and utility sectors. Reporting to the Manager, Primary Design (Adelaide based), you will be instrumental in the success of our new Perth engineering team, while providing hands-on design expertise.

Key focus areas include:

• Hands on detailed engineering studies (e.g., system studies, earthing, insulation coordination, HV cable sizing)
• Apply well rounded primary design skills (e.g., conductor/busbar sizing, short circuit forces, lightning/lighting studies, substation layouts, equipment specifications)
• Foster a collaborative, knowledge-sharing environment to support team capability growth and play an active role in embedding CPP in our newest location
• Undertake interstate travel to offices and project sites to build strong relationships with key stakeholders – critical to long-term integration and success.
