• Diagnose and resolve issues involving:
• Chillers and thermal management systems
• HVAC and liquid cooling systems
• Wiring harnesses
• FSTOP systems
• Power distribution equipment
• Sensors and controllers
• Networking hardware
• Fire systems
• Other critical BESS subsystems
• Collaborate with Product Engineering, Manufacturing, Supply Chain, Quality, NSD, and Field Service teams to identify and resolve hardware design, deployment, and operational issues.
• Lead and support technical investigations related to field failures, hardware non-conformances, warranty claims, customer escalations, and performance concerns.
• Participate in Root Cause Analysis (RCA) activities, failure investigations, and Lessons Learned reviews to reduce recurring issues and improve fleet reliability.
• Analyze fleet-wide failure trends and work with engineering teams to implement corrective and preventive actions.
• Support hardware upgrade, retrofit, and serviceability initiatives by validating compatibility, identifying risks, developing implementation plans, and supporting execution.
• Develop troubleshooting guides, repair instructions, service bulletins, and technical documentation to improve field support capabilities.
• Provide technical guidance to Field Service Engineers, Technical Support teams, Customer Operations groups, and other internal stakeholders.
• Support factory acceptance testing, commissioning activities, and post-deployment investigations.
• Monitor hardware obsolescence and end-of-life (EOL) risks across the fleet.
• Partner with Supply Chain and Product teams to identify replacement strategies, evaluate alternate components, and support lifecycle management initiatives.
• Support spare parts planning by validating BOMs, reviewing hardware configurations, identifying replacement parts, and coordinating critical spare part procurement to maintain customer uptime.
