Principal Engineer - Substations

About Us EPEC Group is a nationally recognised high-voltage engineering and EPC partner, providing HV power engineering, EPC (for substations, lines and BESS BoP), testing and compliance services, along with market modelling, SCADA and Hardware-in-the-Loop capability.

Since being founded in 2019, EPEC has grown rapidly to become a trusted delivery partner on some of Australia’s most complex renewable energy projects, from 400 MW solar farms and 200 MW battery storage systems to 330 kV substations delivered for international developers entering the Australian market for the first time. Founded by specialists in power system engineering, project delivery and generator compliance, our mission is to simplify the grid connection process and remove the uncertainty that costs projects time and money.

We manage connections to the National Electricity Market (NEM) through end-to-end solutions, from pre-enquiry through to connection, registration, testing, compliance and commercial operations. What sets EPEC apart is that everything is delivered in-house: power system modelling, EPC construction, SCADA, commissioning and compliance testing, all under one roof and one point of accountability.

The Role We are looking for a Principal Primary Design Engineer to lead and grow a primary design team delivering FEED (Front-End Engineering Design) and procurement-level design services to a wide array of clients. This role includes overseeing the technical development of primary designs from concept through to FEED and procurement-ready documentation, ensuring compliance with industry standards and providing expertise in substation systems, primary plant and equipment selection.

A key element of this role will be building and mentoring a design team around you, uplifting capability and delivery capacity as our client base grows. Previous experience delivering complex high voltage grid connection projects, as well as developing detailed primary designs, single line diagrams, layout drawings and equipment specifications to a procurement-ready standard, will be essential.

Day to day you will oversee the preparation of FEED studies, concept and preliminary designs and technical specifications, ensuring designs are ready for tender and construction across a diverse portfolio of clients and projects. As our SME, leverage your expertise to provide guidance on primary plant selection, equipment specification and design standards, ensuring compliance with industry standards (AS/NZS, IEC, etc.) and client requirements.
