About the Role

We are seeking an experienced Mechanical Application Engineer with a strong background in thermal management, cooling systems, and mechanical infrastructure for data centers or other mission-critical facilities. This customer-facing role supports the design, application, installation, commissioning, and troubleshooting of cooling and thermal management systems. The engineer will collaborate with customers, internal engineering teams, equipment suppliers, contractors, and field personnel to develop practical solutions and resolve technical issues throughout the project lifecycle. The ideal candidate has at least five years of relevant engineering experience, strong knowledge of mechanical and thermal systems, and the ability to travel to project sites for installation support, commissioning, and troubleshooting.

Responsibilities

• Support the design and application of thermal management and cooling systems for data centers and mission-critical facilities.
• Develop and review mechanical system designs, equipment selections, specifications, calculations, drawings, and technical documentation.
• Evaluate cooling requirements based on IT load, heat rejection, redundancy requirements, operating conditions, and facility design criteria.
• Support the design and integration of chilled-water systems, air-cooled and water-cooled chillers, cooling towers, pumps, heat exchangers, CRAH and CRAC units, in-row cooling, liquid cooling, coolant distribution units, piping, and controls.
• Review equipment performance, pressure drop, flow requirements, temperatures, heat loads, and system capacity.
• Coordinate cooling equipment interfaces with electrical, controls and building management systems, structural, and other data center infrastructure.
• Review vendor submittals, equipment specifications, drawings, and technical proposals for compliance with project requirements.
• Participate in design reviews and provide technical recommendations to customers and internal project teams.
• Serve as a customer-facing technical resource by clearly communicating engineering requirements, proposed solutions, design considerations, and issue resolution.
• Travel to customer and project sites to support installation, commissioning, startup, testing, and troubleshooting.
• Troubleshoot field issues involving equipment performance, cooling capacity, flow, temperature, controls, mechanical installation, and system integration.
• Perform root-cause analysis and coordinate corrective actions with customers, contractors, vendors, and engineering teams.
• Support factory acceptance testing, site acceptance testing, commissioning, and system performance verification as required.
• Resolve RFIs, field changes, and equipment interface issues during project execution.
• Capture lessons learned from field installations and incorporate them into future designs and application improvements.

Qualifications

• Bachelor's degree in Mechanical Engineering or a related engineering discipline.
• At least five years of relevant experience in mechanical engineering, thermal systems, HVAC, cooling systems, or mission-critical infrastructure.
• Experience with data center cooling systems is strongly preferred.
• Strong understanding of thermodynamics, heat transfer, fluid mechanics, HVAC systems, pumps, piping, heat exchangers, and thermal management.
• Familiarity with traditional air cooling and high-density or liquid cooling solutions is preferred.
• Experience reviewing mechanical drawings, P&IDs, equipment layouts, specifications, and technical submittals.
• Understanding of data center redundancy, reliability, uptime, N+1, and 2N configurations is preferred.
• Experience with mechanical equipment commissioning, field installation, startup, or troubleshooting is highly desirable.
• Strong analytical and problem-solving skills, with the ability to diagnose issues in the field.
• Excellent written and verbal communication skills and confidence presenting technical information to technical and non-technical stakeholders.
• Ability to collaborate across engineering, sales, project management, construction, commissioning, and service teams.
• Ability to travel approximately 25 percent, including travel to customer and project sites.

Preferred Skills

• Hyperscale, colocation, or enterprise data centers
• High-density computing and AI data center cooling
• Chilled-water plants and central utility systems
• CRAH, CRAC, and air-handling systems
• Cooling towers and heat-rejection systems
• Pumps, piping, valves, and heat exchangers
• Building management systems and cooling controls
• Mechanical commissioning and functional performance testing
• Computational fluid dynamics or thermal modeling
