Thermal Systems Lead Engineer, Electrical & Power #3612649

Join a high-performing engineering team focused on advancing next-generation thermal systems for high-density data center, AI, HPC, and mission-critical environments. This organization is helping shape the future of cooling infrastructure by developing practical, scalable, and sustainable solutions that support rapidly evolving compute demands.

This team works at the intersection of mechanical systems, thermal performance, controls, infrastructure, and product development. The Mechanical Cooling Loop Lead will help define how rack, room, and facility heat loads are managed through liquid cooling integration, chilled water systems, dry coolers, heat exchangers, pumps, thermal storage, and heat-rejection strategies.

This is an opportunity to influence the architecture and deployment of advanced data center cooling systems while partnering with engineering, product, controls, field, sales, and customer-facing teams.

This is a full-time direct hire opportunity supporting a high-growth data center thermal systems portfolio.

The role offers the chance to help define mechanical cooling architectures for AI and high-density compute environments, including systems that must balance reliability, efficiency, scalability, serviceability, cost, and deployment readiness.

Remote flexibility may be considered for exceptional candidates, with travel expected as needed for customer meetings, technical reviews, field validation, industry events, and project support.

• Lead mechanical cooling loop concept development for advanced data center thermal systems.
• Evaluate and define cooling architectures involving chillers, dry coolers, cooling towers, pumps, heat exchangers, CDUs/TCS, chilled water systems, glycol loops, thermal storage, and heat-rejection systems.
• Translate rack, room, and facility-level heat loads into practical mechanical system requirements.
• Develop system concepts, piping schematics, mode tables, operating strategies, sequence-of-operation inputs, and reference design content.
• Evaluate equipment operating limits, redundancy strategies, control capabilities, commissioning readiness, and system-level performance tradeoffs.
• Partner with product, engineering, controls, modeling, sales, field, manufacturing, and customer-facing teams to support scalable cooling solutions.
• Support field validation, system troubleshooting, digital analysis, and jobsite performance review.
• Provide technical guidance for strategic pursuits, customer discussions, industry events, and commercialization activities.
• Mentor engineers and help transfer practical data center cooling knowledge across teams working on emerging thermal systems.

• 8+ years of relevant engineering experience in data center cooling, mission-critical mechanical systems, HVAC, thermal-fluid systems, mechanical infrastructure, or advanced cooling products.
• Direct experience with data center or mission-critical cooling systems, including chilled water systems, chiller plants, dry coolers, cooling towers, pumps, heat exchangers, CRAH/CRAC/AHU systems, CDUs/TCS, or heat-rejection systems.
• Strong system-level understanding of how rack-level heat loads connect to room-level, facility-level, and heat-rejection systems.
• Experience with piping schematics, hydronic calculations, pump/head calculations, flow distribution, pressure drop, redundancy, control modes, or sequence of operations.
• Familiarity with thermal storage, ride-through strategies, demand limiting, energy optimization, or utility coordination is strongly preferred.
• Experience with commissioning, field validation, BAS/BMS integration, controls, or operational troubleshooting is strongly preferred.
• Ability to evaluate complex mechanical systems with a practical, real-world engineering mindset.
• Strong communication skills with the ability to present technical concepts to customers, leadership, engineering teams, field teams, and industry stakeholders.
• Exposure to OCP, ASHRAE TC 9.9, IEEE, ASME, or other data center / mechanical systems standards organizations is preferred.
• Professional Engineering license, advanced degree, conference participation, standards work, publications, or technical presentations are helpful but not required.
