Senior Electrical Estimator - High Voltage

Nebula Contractors Pty Ltd – Wetherill Park NSW

At Nebula Elec, we deliver critical high‑voltage infrastructure across data centres, switchyards, and substations. We're scaling rapid, and with that growth we now have the opportunity to welcome an estimator at a Senior level - someone who brings a first principles estimating approach to deliver our high voltage project pipeline.

So what's it actually like working at Nebula Elec?

We're at a crucial stage of growth, and with that naturally comes an opportunity to cement your spot and grow with a company that's scaled to nearly 60 employees and has worked on major projects in the space of 5 years. The words'great company culture' get thrown around quite a bit - and while hard to define; our office team of 11 are a humble group collaborating and working on shared goals. You're given breathing room to deliver your work through autonomy and trust, support when you need it, encouragement to voice your opinion on better ways of doing things, and flexibility - we understand the importance of commitments outside of office hours and we work with you on that.

Some insight into the role.

Based in our Wetherill Park office, you will take end-to-end ownership of our medium and high voltage pipeline, with a primary focus on HV Infrastructure like switchyards, substations, and major network connections. While we also handle broader civil and ASP scopes, your expertise will be dedicated to pricing complex, multi‑tiered electrical scopes.

Own the full estimating process across major MV/HV switchyard, substation, and data centre projects, from first scopes, to final tender submission, and project handover.

Prepare comprehensive, technically accurate bids by pricing complex primary and secondary plant, switchgear, protection networks, and associated works.

Develop pricing models through close, continuous collaboration with our internal engineering/project management team and suppliers.

Conduct detailed risk and scope analysis on incoming specifications.





Produce detailed quantity take-offs that reflect true project complexities.

Participating in post‑tender contract reviews, commercial reporting, and claims scoping as projects transition cleanly into the delivery phase.

Drive the commercial capability of the business by building and refining scalable estimating processes and pricing tools as our pipeline grows.

Attend client meetings, nurture these relationships and attend site visits as required.

Who we're looking for.

You have a proven track record pricing complex electrical tenders, desirably with exposure to high‑voltage environments. Your technical background means you can comfortably work through utility specifications, evaluate protection schemes, and understand how projects are run.

You'll bring an Electrical or Engineering Qualification, or a solid technical trade background. We are looking for someone with 5+ years of experience working with estimating teams and who has put runs on the board pricing both infrastructure and smaller projects. You know what it takes to deliver bids in a structured, high‑volume environment, have great communication and presentation skills, and bring a positive, practical attitude to the team.

Valid Australian Working Rights.

Previous experience estimating within the Electrical Sector.

The ability to interpret engineering drawings and specifications.

Strong attention to detail and analytical problem‑solving skills.

Excellent communication, negotiation, and interpersonal skills.

Strong proficiency in estimating software.

Remuneration on offer.

$170,000 – $190,000 + Superannuation. Are we open to negotiating? Sure! If your expectations sit outside of this range, let us know - we understand people bring different levels of experience and we're open to discussions within reason.

Backing Your Growth.

We're not about ticking a training box once a year and calling it done. We run sessions tied to what you're actually working on, and if there's a course, ticket, or qualification that'll make you better at the job, we're happy to have that conversation.
