Résumé du poste

e-STORAGE, a Canadian Solar subsidiary, seeks a Senior BESS Inverter Performance Engineer to diagnose inverter-related issues across operating BESS projects and drive corrective actions with vendors. You will identify root causes across software, firmware, controls, hardware, or site conditions and own retrofit execution tracking using Excel/Smartsheet.

You will lead root cause analysis, review firmware/design changes, and work with vendors to define actions, schedules, and validation criteria

Qualifications

• Engineering degree in electrical, computer, or mechanical engineering with 5+ years in renewable energy or BESS.
• Strong knowledge of inverter operation, firmware/software behavior, controls logic, and hardware design.
• Power systems knowledge including voltage control, frequency response, and real/reactive power behavior.
• Ability to manage multiple technical issues with organization and follow-through.
• Experience troubleshooting inverter or BESS performance using operational data and event logs.
• Experience managing corrective actions or retrofit rollouts across multiple sites.
• Proficiency with Excel, Smartsheet for logs, dashboards, and action follow-up.
• Knowledge of SCADA protocols (DNP3, Modbus).
• Familiarity with industrial networks (fiber optics, TCP/IP).
• Clear technical communication with vendors, site teams, engineering, and management.
• Ability to travel up to 20% of time.

Responsabilités

• Prioritize, investigate, and drive corrective actions for inverter-related performance issues across operating BESS projects.
• Perform root cause analysis using data, first principles, site evidence, and technical review to distinguish software, firmware, controls, hardware, design, and power system issues.
• Maintain vendor issue logs including status, root cause, corrective action, validation, and closure.
• Review vendor release notes, firmware updates, design changes, and retrofit proposals for technical adequacy and risk.
• Define corrective actions, retrofit requirements, implementation plans, validation criteria, and deployment schedules with inverter vendors.
• Support troubleshooting of voltage, frequency, real power, and reactive power distribution with site or grid conditions.
• Track retrofit rollouts across sites with assets, owners, deployment status, validation evidence, risks, and closure criteria.
• Ensure all activities comply with safety protocols and engineering standards.
