What you’ll achieve

This role is critical to enabling next-generation AI and high-density computing by ensuring reliable, efficient, and scalable thermal solutions. You will directly influence customer success and shape the future of data center cooling technologies.

We are seeking a highly skilled Mechanical / Thermal Engineer specializing in Direct Liquid Cooling (DLC) to support customer-facing deployments of advanced data center infrastructure. This role bridges engineering design, system integration, and customer engagement, ensuring optimal thermal performance and reliability of high-density compute platforms. The ideal candidate will work directly with customers, internal engineering teams, and partners to deliver innovative cooling solutions at scale.

You will:

• Serve as the technical subject matter expert (SME) for mechanical and thermal systems, with a focus on DLC technologies in customer environments
• Lead customer engagements, including design reviews, site readiness assessments, and deployment support for liquid-cooled systems
• Collaborate with cross-functional teams (electrical, systems, manufacturing, and field engineering) to ensure end-to-end thermal solution delivery; influence product design by incorporating customer feedback and field learnings into next-generation solutions
• Analyze and optimize thermal performance of racks, servers, and cooling distribution units (CDUs) under real-world operating conditions; develop and present technical documentation, whitepapers, and customer-facing materials
• Support installation, commissioning, and troubleshooting of DLC systems, including manifolds, cold plates, and facility integration; provide root cause analysis and corrective actions for thermal or mechanical issues encountered during deployments
