Senior BESS Inverter Performance Engineer

This position is listed on behalf of a partner company, which manages all applications and next steps. Our partner is looking for a Senior BESS Inverter Performance Engineer based in the United States.

As a Senior BESS Inverter Performance Engineer, you will play a key role in improving the performance, reliability, and operational efficiency of utility-scale battery energy storage systems (BESS). You will investigate complex inverter-related issues, identify root causes, and coordinate corrective actions with technology vendors and engineering teams. Your work will involve evaluating software, firmware, control logic, hardware, and grid-related factors to ensure optimal system performance. You will also oversee retrofit implementation across multiple sites, monitoring deployment progress, validation results, risks, and resolution milestones. Working in a collaborative, innovation-driven renewable energy environment, you will partner with technical stakeholders to enhance system reliability and support continuous improvement. This remote opportunity offers the chance to contribute to large-scale energy storage projects and accelerate the transition toward a cleaner, more resilient energy future. \n

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. Benefits
