• Reviewing grid code compliance and relevant Australian standards as part of project scoping
• Supporting commercial negotiations and contract review from a technical standpoint
• Building strong, ongoing relationships with developers, EPCs, and asset owners across the sector
• Staying close to the market: technology shifts, competitor products, and regulatory change

What you'll bring

• 5 to 15 years' experience in renewable energy applications engineering
• A degree in Electrical Engineering, Power Engineering, or a related technical discipline
• Strong working knowledge of BESS architecture, inverters, transformers, EMS/BMS platforms, and balance-of-system equipment
• Familiarity with relevant grid codes and standards for the Australian market
• Confidence presenting technical solutions to clients and defending design decisions
• The ability to translate complex engineering detail into commercially useful insight for non-technical stakeholders
• A collaborative approach, sound judgement, and the ability to work with minimal supervision
