Senior BESS Inverter Performance Engineer

Job description

**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. ### 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 - **Competitive compensation:** Annual base salary ranging from $100,000 to $140,000, plus performance-based bonus opportunities. - **Comprehensive benefits:** Access to health coverage and a range of employee benefits. - **Retirement plans:** Retirement benefits to support long-term financial well-being. - **Paid time off:** Paid leave to support personal needs and work-life balance. - **Remote work flexibility:** The opportunity to work remotely from the United States. - **Professional development:** Opportunities to expand technical expertise and develop your career in the renewable energy and energy storage sectors. - **Meaningful work:** Contribute to utility-scale energy storage projects that improve grid reliability and enable greater integration of renewable energy. - **Collaborative culture:** Work alongside multidisciplinary teams and technology partners in an environment that values innovation, integrity, quality, and customer focus. - **Inclusive workplace:** Join a team committed to diversity, equity, inclusion, and respect for different backgrounds and perspectives.
