• Serve as the primary technical support contact for customers, channel partners, and field service technicians supporting LiquidStack products.
• Diagnose and resolve mechanical, thermal, fluid, and electromechanical system issues using structured troubleshooting and technical analysis.
• Support mission-critical customer environments by helping resolve technical issues quickly to maximize system performance and uptime.
• Analyze product issues using engineering documentation, including mechanical drawings, electrical schematics, bills of materials (BoMs), service manuals, and CAD models.
• Perform structured root cause analysis (RCA) on recurring technical issues and collaborate with Engineering and Quality teams to recommend corrective actions and improve product reliability.
• Partner with Engineering, Manufacturing, Supply Chain, Quality, and Global Services teams to resolve complex technical challenges and improve serviceability.
• Support product lifecycle activities, including installation support, commissioning assistance, warranty evaluations, spare parts coordination, upgrades, and service recommendations.
• Utilize CRM and service management systems to accurately document troubleshooting activities, technical findings, customer communications, and case resolutions.
• Develop and maintain technical documentation, troubleshooting guides, knowledge base articles, and best practices to improve service efficiency.
• Serve as the technical voice of the customer by communicating recurring field issues, customer feedback, and product improvement opportunities to internal teams.
• Communicate complex technical information clearly and professionally to customers, service partners, and cross-functional stakeholders.
• Support a global customer base across multiple time zones while maintaining exceptional customer service.
