- Manage relationships with OEMs, EPC contractors, and technical advisors; lead technology and vendor selection processes
- Provide technical leadership on grid connection studies, AEMO compliance, and interconnection requirements for BESS assets
- Oversee HAZOP, safety case development, and compliance with relevant Australian standards (AS/NZS) and battery safety codes
- Build, lead,



and mentor a growing team of BESS engineers as the portfolio scales
- Support commercial and investment teams with technical input for PPAs, offtake structuring, and revenue stacking (FCAS, arbitrage, capacity)
- Represent the business in interactions with AEMO, network service providers (NSPs), regulators, and industry bodies
- Report on technical progress, risks, and budget to the executive team and board

Candidate Requirements
- Minimum 12 years of engineering experience in power systems, renewable energy, or utility-scale infrastructure, with substantial hands-on BESS experience (minimum 4–5 years specifically in BESS)
- Proven track record delivering utility-scale BESS projects in Australia, from development through to operations
- Deep technical knowledge of BESS technologies (lithium-ion chemistries, inverter/PCS design, thermal management, fire suppression systems)
- Strong understanding of the NEM, AEMO frameworks, grid connection processes, and Australian technical standards
- Experience leading technical due diligence for M&A; or investment processes
- Demonstrated people leadership — building and managing engineering teams
- Bachelor's degree in Electrical Engineering, Power Systems, or related discipline; Chartered Engineer (CPEng) status highly regarded
- Excellent stakeholder management skills, with experience presenting to investment committees and boards
- Full working rights in Australia; Sydney-based (or willing to relocate)

What's on Offer
- Senior leadership role with a fast-growing, well-capitalised platform
- Direct influence over technology strategy and portfolio-shaping decisions
- Competitive base salary + bonus + potential equity/LTI, commensurate with seniority
- Growth opportunities as the BESS pipeline scales
