This role focuses on energy resilience, safety logic, and performance analytics, ensuring that renewable energy assets are safely and efficiently integrated into the Google infrastructure. The Engineer reviews grid-tie sequences, inverter logic (Modbus/TCP), and fire/thermal safety protocols (for BESS) to ensure compliance with GPR standards and safety best practices. This role interacts with sustainability leads, fire life safety teams, and third-party solar/battery installers (e.g., Tesla) to manage the full project lifecycle from design intake to performance telemetry onboarding. **Responsibilities:** **Design and Engineering:** - Conduct design reviews for PV and BESS electrical infrastructure to ensure compliance with grid-tie requirements, GPR safety standards, and client-specific design guidelines. - Perform technical reviews of inverter control sequences, Modbus mapping, and BESS fire suppression/thermal runaway logic. - Conduct field inspections of array placement and safety equipment (Rapid Shutdown) to proactively identify implementation risks and deviations from the approved design. - Coordinate with project teams and represent the client on the project team to ensure safety and sustainability requirements are effectively resolved within the project schedule. - Collaborate with installers and consultants to ensure system communication protocols match Google Network security requirements. **Project Management:** - Manage multiple PV and BESS projects simultaneously, ensuring timely design sign-off and KPI adherence. - Provide regular progress updates regarding energy production estimates vs. actual performance ratios (PR). - Proactively identify process deficiencies in the renewable energy onboarding workflow and develop improvements. - Ensure internal records, safety manuals, and performance databases are verified via ongoing quality assurance (Gate 5). - Prepare and present performance analytics reporting to stakeholders to drive sustainability goals. **Implementation and Commissioning:** - Oversee the installation and configuration of communication gateways and secure network drops outside the building envelope. - Develop and execute comprehensive commissioning plans for rapid shutdown sequences and BESS charge/discharge cycles. - Troubleshoot inverter communication and resilience failover issues during commissioning and operation. - Perform "Performance Telemetry Onboarding" to transition new assets onto monitoring servers and validate data accuracy. - Evaluate operating trends subsequent to commissioning to validate that peak-shaving and energy storage logic is performing as designed. **Qualifications required:** - Bachelor's degree in Electrical Engineering, Renewable Energy Engineering, or a related facilities field with energy storage experience. - 4-7 years of experience in Solar PV design, BESS integration, or renewable energy infrastructure. - Strong knowledge of inverter control theory, Modbus/TCP, and safety standards for energy storage (e.g., UL 9540). - Experience with major PV/BESS platforms and energy monitoring software (Performance Ratio validation). - Demonstrated ability to organize and manage multiple simultaneous proje…
