Senior BESS Inverter Performance Engineer

Accountabilities: Investigate, prioritize, and drive corrective actions for inverter-related performance issues across operational battery energy storage projects. Conduct root cause analyses using operational data, event logs, site evidence, engineering principles, and technical reviews to distinguish between software, firmware, controls, hardware, design, and power system issues. Collaborate with inverter vendors to establish corrective actions, define retrofit requirements, develop implementation plans, and agree on validation criteria and deployment schedules. Maintain comprehensive vendor issue logs documenting investigation status, root causes, corrective actions, validation results, outstanding risks, and final resolution. Review firmware updates, software releases, design changes, and proposed retrofits to assess their technical suitability, operational risks, and potential performance impacts. Troubleshoot voltage regulation, frequency response, real power, and reactive power distribution issues, particularly where inverter behavior interacts with site conditions or grid requirements. Coordinate retrofit rollouts across multiple sites, tracking affected assets, assigned owners, deployment status, validation evidence, risks, and closure criteria. Use Excel, Smartsheet, or comparable tools to maintain issue trackers, retrofit schedules, deployment dashboards, and corrective action reports. Communicate technical findings, recommendations, risks, and progress updates clearly to vendors, site teams, engineering stakeholders, and management. Ensure all troubleshooting and corrective actions comply with applicable safety protocols, engineering standards, and organizational policies. Requirements Bachelor's degree in Electrical Engineering, Computer Engineering, Mechanical Engineering, or a related engineering discipline. At least five years of experience in renewable energy, battery energy storage systems, or a closely related technical field. Strong knowledge of inverter operation, dispatch controls, firmware and software behavior, control logic, and hardware design considerations. Experience diagnosing inverter or BESS performance issues using operational data, event logs, and technical evidence. Understanding of power systems, including voltage control, frequency response, and real and reactive power behavior in grid-connected environments, is preferred. Proven experience coordinating corrective actions or retrofit deployments across multiple sites, including schedule management, stakeholder follow-up, progress tracking, risk assessment, and closure reporting. Proficiency in Microsoft Excel, Smartsheet, or similar tools for technical issue tracking, deployment management, and reporting. Knowledge of SCADA protocols such as DNP3 and Modbus. Familiarity with industrial communication networks and technologies, including fiber optics, network switches, and TCP/IP. Strong analytical and troubleshooting skills, with the ability to investigate complex technical problems and manage multiple issues simultaneously. Excellent organizational skills, attention to detail, initiative, and consistent follow-through on technical deliverables. Strong written and verbal communication skills, with the ability to explain technical findings and recommendations to diverse stakeholders. A collaborative mindset and commitment to safety, quality, ethical practices, innovation, and sustainability. Willingness and ability to travel up to 20% of the time, including occasional travel on short notice.
