• Coordinating with civil, structural, and secondary disciplines to deliver integrated design outcomes

• Supporting system integration, requirements management, and design verification processes

• Leading the resolution of complex technical issues, balancing cost, time, and quality constraints

• Driving design optimisation, constructibility, and innovative engineering solutions

What you'll need to succeed

• Degree in Electrical Engineering

• Extensive experience in HV primary design (220kV+ preferred)

• Strong substation and transmission project exposure

• Proven experience leading design delivery on large-scale projects

• Solid understanding of Australian standards and grid compliance

• Experience in EPC, utilities, or consultancies highly regarded
