Principal Liquid Cooling Engineer – Data Centers Location: Remote, United States | Up to 50% Travel Salary: $160,000 – $190,000 Base + Benefits Industry: Data Centers | Advanced Cooling | Mission Critical Infrastructure The Opportunity As AI and high-performance computing continue to transform the data center industry, demand for advanced liquid cooling technologies is accelerating rapidly. We're partnering with a growing engineering business supporting the deployment and operational readiness of advanced cooling infrastructure across major US data center projects. We're seeking an experienced Principal Liquid Cooling Engineer to provide technical leadership across complex cooling and fluid systems, helping establish engineering standards, resolve technical challenges and support successful project delivery. This is a senior individual contributor opportunity, combining technical expertise, engineering standards development and collaboration with leading organizations across the mission-critical infrastructure sector. What You'll Be Doing Develop and maintain technical standards and best practices for direct-to-chip liquid cooling systems. Provide engineering expertise across system design, installation, commissioning, maintenance and operations. Review engineering specifications, designs and construction documentation, identifying technical risks and improvements. Lead technical investigations, root cause analysis and corrective action recommendations. Support troubleshooting across cooling distribution units (CDUs), pumps, valves, piping networks and associated fluid systems. Develop and deliver technical training for engineering and project delivery teams. Collaborate with contractors, OEMs, engineering consultants and customers to resolve complex technical challenges. Contribute to industry knowledge sharing and continuous improvement initiatives. What We're Looking For 5+ years of experience in mission-critical infrastructure, high-purity process cooling or complex mechanical and fluid systems. A degree in Mechanical Engineering, Chemical Engineering or a related technical discipline. Strong understanding of hydronic systems, process cooling, fluid distribution networks or high-purity piping. Experience across engineering design, construction, commissioning or operations. Knowledge of direct-to-chip liquid cooling technologies would be highly advantageous. Strong technical troubleshooting, root cause analysis and engineering documentation skills. Experience developing engineering standards, technical procedures or best practices. Excellent communication skills and confidence engaging with customers, contractors and technical stakeholders. We're also interested in engineers from adjacent industries, including semiconductor manufacturing, high-purity fluid systems and advanced process cooling, who bring transferable technical expertise. Why Consider This Opportunity? Technical influence: Help define engineering standards and best practices for next-generation liquid cooling infrastructure. AI infrastructure exposure: Work on advanced cooling technologies supporting high-density data center environments. Senior individual contributor role: Remain technically involved without moving into traditional people management. Industry collaboration: Work alongside leading OEMs, engineering organizations and mission-critical infrastructure providers. Career development: Join a growing business with opportunities to influence technical direction. Remote flexibility: US-based remote position with up to 50% nationwide travel.
