Job description

Imagine helping commission the electrical systems powering major data centres, utilities, industrial facilities and critical infrastructure projects.

You’re not just sitting behind a desk.

You’re out on-site testing protection systems and HV equipment, solving complex faults and making sure critical electrical assets are safe, reliable and ready to perform.

Sound cool? We know.

This isn’t just another electrical role.

It’s an opportunity to join one of Australia’s leading Tier One electrical contractors, working across some of the region’s most significant infrastructure and construction projects.

Your practical experience will matter here.

You’ll be trusted to lead and personally undertake protection testing, HV equipment testing and onsite commissioning activities across a growing project portfolio.

You’ll also help plan testing and commissioning works, interpret results, prepare technical documentation and provide practical recommendations when things don’t go to plan.

This is a genuinely hands‑on position.

You’ll spend much of your time in the field, while still having the opportunity to influence commissioning strategies, guide developing team members and strengthen the technical capability of the broader team.

As an HV Commissioning Engineer / Technician, you’ll lead the testing, verification, fault‑finding and commissioning of electrical protection systems and HV equipment.

One day, you could be completing protection relay and primary or secondary injection testing for a major data centre.

The next, you could be commissioning transformers, switchgear, generators, circuit breakers or associated HV and MV equipment on a complex infrastructure site.

You’ll work across the entire commissioning process, from initial planning and readiness reviews through to testing, fault‑finding, documentation and final handover.

You’ll review and configure relay settings across platforms such as Schneider Electric, Siemens and ABB, verify protection schemes against approved drawings and analyse test results to identify faults or abnormalities.

Where appropriately qualified and authorised, you may also perform or coordinate HV switching activities and assist with the development of switching instructions and programs.

You’ll work closely with Project Managers, engineers, technicians, tradespeople and clients to coordinate onsite activities and keep projects moving safely and efficiently.

You’ll also prepare and review test procedures, ITPs, commissioning plans, test records and technical reports.

The role will involve travel across metropolitan, regional and, when required, remote project locations.

This isn’t your typical electrical contractor.

For more than 100 years, this Australian-owned business has been helping shape the country’s electrical infrastructure.

From data centres and utilities to industrial facilities and major infrastructure developments, they deliver complex projects where safety, reliability and technical capability matter.

Based in Penrith, you’ll join a growing Western Sydney team with a strong pipeline of current and upcoming work.

Growth is a genuine part of the story here.

They are continuing to build their protection, testing and commissioning capability and are looking for someone who can become a trusted technical figure within the team.

Retention is important to them, and you’ll feel that firsthand through the development opportunities, project exposure and long‑term career pathways available.

You’re a hands‑on HV commissioning and testing professional with demonstrated experience across HV or MV power systems.

You’ll hold a relevant electrical engineering qualification or equivalent recognised technical qualification.

Depending on your background and the work you perform, you’ll also bring the relevant electrical licence, HV switching qualifications, access credentials or network authorisations.

You may currently be working as an HV commissioning engineer, protection engineer, HV testing technician, leading hand or senior HV electrician.

What matters most is your practical capability.

You’re confident with protection relay testing, primary and secondary injection testing and fault‑finding across protection, control and HV systems.

Experience testing and commissioning transformers, switchgear, generators or other HV and MV primary plant will be highly regarded.

You understand protection principles and can interpret single‑line diagrams, schematics, protection drawings and control wiring diagrams.

You don’t need to have worked across every relay platform, piece of equipment or project environment listed in a traditional position description.

If you bring strong protection testing experience, practical HV knowledge and the ability to troubleshoot complex problems safely, we want to hear from you.

You’re also someone others naturally turn to for advice.

You can lead onsite activities, mentor engineers and technicians and communicate technical information clearly with clients and project teams.

Data centres, utilities, generation, transmission, distribution or heavy industry?

You know your way around complex electrical environments.
