Job description

Senior Electrical Engineer - Underground Mining

At EMtek, we’re a multidisciplinary engineering team built on strong values, ethics, and expertise. We provide professional, technical, and project management services across structural, mechanical, process, piping, civil, electrical, instrumentation, safety, control, communications, and software engineering.

With more than 140 talented people across offices in Melbourne, Perth, Brisbane, and Ballarat, plus site offices throughout Victoria and Western Australia, we work seamlessly across locations to deliver results.

Our vision is to tackle industry challenges with agile, intelligent, and innovative solutions, supporting projects from concept through to operation. We work across diverse industries including resources, materials handling, infrastructure, power, renewables, and decarbonisation, partnering with leading clients such as Roy Hill/Hancock, Rio Tinto, Fortescue, and Newmont.

Position Overview

We are pursuing a significant underground development and infrastructure upgrade project for a major Australian gold producer, and we are looking for a Senior Electrical Engineer to help us win it and then deliver it.

You will be central to bid development - shaping the electrical scope, building the estimate, developing the execution methodology and helping put the proposal in front of the client. On award, you carry that scope into delivery as the senior electrical engineer on the project, taking the design from concept through to IFC and into construction and commissioning support.

It suits someone who knows underground mine electrical infrastructure - reticulation down a decline, underground substations, ventilation and dewatering, earthing and earth fault protection in an underground environment. Based in our Brisbane office, reporting to the Electrical Engineering Manager.

Lead electrical and instrumentation input into bids, proposals and tender submissions - scope definition, estimate development, execution methodology and technical narrative

Develop the assumptions, qualifications, exclusions and risk register that sit behind the price

Contribute to win themes, client presentations, tender clarifications and interview stages

Take underground electrical designs from concept through to detailed IFC deliverables

Design underground power reticulation

Prepare power system studies for an extending underground network - load flow, voltage drop over long reticulation runs, fault level, protection coordination, arc flash and earth fault limitation

Design earthing, earth leakage and earth continuity monitoring systems appropriate to underground operation

Prepare designs and calculations

Produce the full deliverable set - SLDs, schematics, loop and termination diagrams, cable schedules and calculations, equipment lists, datasheets, specifications, vendor packs, functional descriptions, ITPs, O&M manuals

Support configuration and commissioning of protection devices, VSDs, instrumentation and control systems

Coordinate with mechanical, civil, structural, ventilation and mining engineering disciplines, and with the client’s site electrical team

Provide technical review and mentoring across a growing electrical and controls team

Site visits to underground operations as required, and a visible safety focus throughout

Skills and experience - essential

Tertiary qualification in Electrical Engineering

Minimum 8 years’ electrical engineering experience, including at least 4 years designing or delivering underground mine electrical infrastructure. Hard rock metalliferous is strongly preferred

Demonstrated underground reticulation design experience - HV distribution underground, cable selection and sizing for mining service, underground substations, switching and protection, earthing and earth fault protection in an underground environment

Demonstrated bid and proposal experience - you have built electrical estimates, written technical proposal content and owned a scope through a competitive tender, not just contributed a cable schedule to someone else’s submission

Proven design engineer across switchrooms, switchboards, MCCs, LV and HV, VSDs, transformers, lightning protection and earthing systems, with calculations and documentation you can evidence

Working knowledge of AS/NZS 4871 and the Australian mining electrical regulatory framework

Ability to interface with clients and stakeholders at all levels

Skills and experience - desirable

Gold sector experience, and familiarity with the operating practices of Australian producers

Underground communications

Power system modelling (ETAP, PowerFactory or similar)

Control systems exposure across SCADA, PLC and RTU platforms, and industrial communications and IP networks

Experience across a range of commodities including gold, copper, lithium and iron ore

Construction, commissioning or operations experience underground

Why you’ll love it here

A professional but relaxed environment with flexible work arrangements

Friendly, down-to-earth team with supportive colleagues and management

Long-term stability with engaging projects in the pipeline

A central Brisbane office location with great cafes and amenities nearby

Opportunities to work from various company state office locations

Career development opportunities in technical engineering design, project and people management

Exposure to projects across Resources, Minerals Processing, Materials Handling, Infrastructure, Power & Renewables and Decarbonisation
