· Lead technical escalation and resolution of systemic equipment issues, including root cause identification and corrective action implementation.

· Provide technical oversight of vendor performance, ensuring equipment issues are properly diagnosed, addressed, and resolved.

· Develop and implement strategies for managing power conversion systems across their lifecycle, including spare parts planning, repowering analyses, and monitoring capabilities.

· Review and validate inverter and BESS firmware, controls logic, and operating parameters to ensure proper system performance and grid compliance.

· Support analysis of inverter and BESS interactions with plant-level controls and grid events to improve system response and stability.

· Identify and evaluate key failure modes and develop mitigation strategies to reduce recurrence and fleet-wide risk.

· Support long-term planning for major component replacements and fleet upgrades.

· Drive reliability improvements through PM optimization, failure trend analysis, and standardization of best practices.

· Support development of condition-based maintenance approaches.

· Provide operational insight to Delivery teams to inform equipment selection and specifications.

· Support commissioning review and project turnover into operations.

· Identify and communicate design or operational deficiencies.

· Collaborate closely with Asset Management, O&M, Performance Engineering, and Compliance teams to improve fleet performance.

Qualifications:
