Gamuda Engineering, a fully owned subsidiary of Gamuda Berhad, is a reputable Engineering and Construction contractor specialising in the design, construction, operation, and maintenance of Transport, Civil, and Energy Infrastructure projects. As a fully integrated energy infrastructure partner, Gamuda provides an end-to-end solution to fund, develop, build, and own assets to accelerate Australia’s transition to clean energy. With a proven track record delivering complex infrastructure projects both in Australia and internationally, Gamuda’s strategy is to invest in, develop, and construct large-scale renewable energy assets with a focus on wind, solar, and Battery Energy Storage System (BESS) developments and EPC projects.

We are currently mobilising our project delivery team to build one of Victoria’s most significant clean energy developments in southwest Victoria—the Mortlake Energy Hub (MEH), an integrated 450 MW solar farm and 600 MW BESS hybrid project.

The Role

Reporting to the Project Manager – Substation & BESS, the Construction Manager (Substation & BESS) will hold end-to-end operational accountability for leading site mobilisation, construction delivery, cost management, quality, safety, and stakeholder engagement across our substation and BESS work packages.

Operating across both the pre-contracts and delivery execution phases, you will direct multidisciplinary site teams—including Senior Project Engineers, Site Superintendents, and specialist subcontractor teams—to ensure all civil benching, structural foundations, high-voltage electrical installations, equipment placement, inverter integration, and commissioning activities are delivered safely, on schedule, and within budget.

Key Responsibilities

• Collaborate closely with Pre-Contracts, Design, and Estimating teams during tender and ECI phases to provide constructability reviews, construction sequencing, delivery methodologies, and value-engineering input.
• Manage day-to-day site construction activities, site mobilisation, and subcontractor performance across all substation and BESS workstreams.
• Oversee civil and structural work packages for substation and BESS installations
• Manage HV electrical construction and mechanical assembly, BESS integration and package delivery.
• Coordinate pre-commissioning, system testing, final energisation, and handover in close collaboration with commissioning leads, Network Service Providers (NSPs), and client representatives.
• Manage project resources, specialist plant, and subcontractor staffing; review and approve subcontractor progress claims, variations, and Extension of Time (EOT) requests; and monitor cost forecasting and risk/opportunity registers.
• Champion a strong site culture across HSE, Environmental Management, Quality, and Community relations, ensuring all works strictly adhere to Australian Standards, Wiring Rules, project specifications, and statutory regulations.

Your Skills & Experience

You will be an accomplished construction leader with substantial experience managing major utility-scale power, substation, or renewable energy infrastructure including:

• 15+ years of site construction leadership experience on major infrastructure projects, with a proven track record delivering utility-scale substations, BESS, or high-voltage energy assets in Australia.
• In-depth technical understanding of substation civil works (earthworks, foundations, drainage, oily water separation) and HV electrical installations (earth grids, transformers, switchgear, and control buildings).
• Solid technical knowledge of BESS architecture, inverter stations, PCS units, HVAC systems, fire suppression systems, and battery storage safety protocols.
• Proven track record leading multidisciplinary site teams, managing specialised electrical subcontractors, and interfacing with major Tier-1 OEMs (battery, inverter, and transformer manufacturers).
• Demonstrated capability across both early-stage ECI / tendering phases and live site execution.
• Strong commercial awareness, schedule management, and proactive problem-solving abilities.
