As our energy team continues to grow, we are seeking a Senior Primary / Power Systems Engineer to join us in Perth.

• Undertake primary system design including substation layouts, earthing and lightning protection, high-voltage equipment selection, busbar ratings, fault studies, and insulation coordination.
• Conduct advanced grid interconnection and system planning studies, including steady-state and dynamic assessments, cable ratings using CYMCAP, and generator integration to ensure system stability.
• Provide technical leadership and guidance on AS Standards, WEM rules, Western Power requirements, and grid connection specifications across both primary and power systems domains.
• Perform Owner’s Engineer duties, including design reviews, site inspections, grid compliance testing, and mentoring junior engineers.
• Collaborate with a team of multi-disciplinary engineers, clients, OEMs, network operators, and contractors producing technical reports, presentations, and supporting strategic renewable and energy transition initiatives.

The following qualifications and experience are highly desired, but if you don’t tick all the boxes, you could still be a perfect fit for this role. Please apply, all applications will be considered.

The qualities that help you thrive:

• Bachelor’s Degree in Electrical or Power Systems Engineering, with 10+ years’ experience in power systems, ideally in consultancy, OEM, or utility network planning. Note: those with exposure to primary design will be highly regarded.
• Proven expertise in power system analysis tools: PSS/E, PSCAD, DIgSILENT PowerFactory, ETAP, and ability to solve complex engineering challenges.
• Deep knowledge of grid connection processes, utility-scale performance standards, WEM rules, and AEMO WEM Power System Modelling guidelines.
• Extensive experience preparing technical design documentation, with strong grasp of control and protection for high-voltage equipment, transmission lines, and generators.
• Exceptional leadership and communication skills, capable of advising clients, guiding teams, drafting proposals, and driving business opportunities under tight deadlines.

Why you’ll love working with us:

• Flexible work arrangements, including alternative start/finish times, part-time, job-sharing and hybrid work options
• Continuous learning and growth - lunch and learns, professional development courses, financial study assistance, 5 days paid study leave, global career opportunities
