- Interpret and review SLDs, layout drawings, interface diagrams, protection settings, and control schematics.
- Collaborate with global R&D; and product teams to address system architecture, equipment configurations, and firmware/hardware integration.
- Depending on background, the Project Engineer may take a lead role in coordinating PPC/EMS/BESS SCADA integration or supporting grid compliance testing and stakeholder engagement during the generator registration process.

Project Execution Support





- Assist in managing technical deliverables and milestones throughout project delivery.
- Coordinate with EPC contractors and site teams during installation, testing, and commissioning phases.
- Coordinate with control system vendors and internal firmware teams on testing of PPC/EMS communication protocols (e.g., Modbus TCP/IP, IEC 61850, DNP3).
- Participate in the review and preparation of documentation for AEMO hold point testing, performance guarantees, and compliance to NER, AS3000, and relevant Australian standards
- Provide technical support during R1/R2 hold point testing, especially for control system behavior (e.g., AGC tracking, frequency response, voltage control).

Interface & Communication

- Act as a key communication bridge between the local project stakeholders (EPC, consultants, customers) and Trina’s overseas technical teams.
- Attend project meetings, track actions, and ensure timely closure of technical issues and document submissions.
- Ensure alignment between site execution and product capabilities through proactive coordination and stakeholder management.

Documentation & Quality Control

- Maintain project document logs including RFIs, NCRs, submittals, and engineering reports.
- Support quality inspections and FAT/SAT planning where required.
- Monitor design and site progress to identify risks, bottlenecks, and opportunities for design improvements.

Qualifications and Skills





- Degree in Electrical Engineering, Power Systems, Renewable Energy, or related discipline.
- Minimum 1–3 years of engineering or site support experience in renewable energy projects, preferably involving battery energy storage, solar PV, wind farm, or grid integration systems.
- Strong understanding of: Battery energy storage system architecture, Inverter and PCS integration
- Experience in any of the following areas is highly regarded: Plant Power Controller (PPC) functional design or integration, Energy Management System (EMS) architecture and logic implementation, Grid connection process, including GPS preparation, R1/R2 hold point testing, and AEMO/NSP coordination
- Familiarity with tools such as: Microsoft Project or Primavera P6 for schedule tracking, Bluebeam or Adobe Acrobat Pro for markups and drawing reviews, SharePoint / Teams / Confluence for collaborative project documentation.
- Hands-on experience with testing/commissioning procedures, especially R1/R2 hold point testing or grid compliance reporting is highly valued.
- Robust interpersonal and problem-solving skills.
- Fluency in English is essential. Mandarin language skills are highly regarded, especially for coordinating with Trina’s global R&D; and engineering teams, but not mandatory.
- Ability to travel to Australian project sites as needed.

What We Offer

- A fast-growing global energy storage team at the forefront of renewable transformation.
- Participation in landmark BESS projects across Australia.
- Cross-functional and international collaboration with world-class product development teams.
- Competitive remuneration and long-term career development in a top-tier renewable energy brand.
