Mechanical Senior Engineer

About the Role Dell Technologies' Infrastructure Solutions Group seeks a Mechanical Senior Engineer specializing in Direct Liquid Cooling (DLC) for AI platforms. You will be a senior technical leader responsible for resolving complex factory and customer escalations, while ensuring deployment and lifecycle support of high-density AI systems. You will operate at the intersection of product engineering, manufacturing, and customer operations to drive reliability, performance, and customer success. What You'll Do

• Lead Customer Escalations & Technical Resolution: Serve as the primary customer-facing mechanical/thermal expert for AI platform escalations, driving end-to-end resolution of critical factory, deployment, and post-deployment issues involving Direct Liquid Cooling (DLC) systems.
• Troubleshoot & Optimize Liquid Cooling Infrastructure: Diagnose and resolve complex issues across cold plates, manifolds, tubing, quick disconnects, CDUs, pumps, flow control, leak detection, and monitoring systems while validating thermal performance, flow balance, and cooling efficiency in real-world environments.
• Drive Reliability, Root Cause Analysis & Continuous Improvement: Conduct deep root cause investigations (RCA), implement corrective and preventive actions (CAPA), analyze fleet-wide telemetry and failure trends, and lead design, quality, and cost improvements based on factory and field feedback.
• Support Product Development & Manufacturing Scale-Up: Partner with cross-functional teams to support new product introductions (NPI), pilot builds, high-volume manufacturing ramps, deployment readiness, and successful integration within customer data center environments.
• Provide Technical Leadership & Stakeholder Communication: Communicate technical findings, mitigation strategies, and recommendations to customers, executives, and field teams while influencing next-generation AI platform and DLC architectures and maintaining engineering documentation, escalation reports, and ECR/ECO records. What We're Looking For
• Essential Requirements: Advanced Mechanical & Thermal Engineering Expertise: Bachelor’s degree in Mechanical Engineering or related field (Master’s preferred) with 5+ years of experience in mechanical and thermal engineering, including deep expertise in Direct Liquid Cooling (DLC), thermal system design, fluid mechanics, heat transfer, and thermal optimization.
• High-Performance Computing & Data Center Knowledge: Strong understanding of AI/HPC platforms, GPU servers, high-density compute environments, and data center cooling infrastructure, including facility-level cooling integration.
• Reliability, Failure Analysis & Issue Resolution: Proven track record in failure analysis, reliability engineering, root cause methodologies, and leading customer-facing escalations and complex field issue resolution.
• Manufacturing & Operational Support: Experience supporting factory operations, manufacturing processes, supplier quality management, and product deployment activities in fast-paced global environments.
• Technical Leadership & Communication: Proficiency with CAD tools (Creo, SolidWorks, NX) and engineering documentation, combined with excellent executive-level communication, multitasking capabilities, and willingness to travel for customer and factory support. Nice to Have
