What are the key skills and qualifications needed to thrive as a Cooling Engineer, and why are they important?

To thrive as a Cooling Engineer, you need a strong background in mechanical or HVAC engineering, thermodynamics, and systems design, typically supported by a relevant engineering degree or certification. Proficiency with CAD software, HVAC design tools, and familiarity with industry standards like ASHRAE are essential. Strong problem-solving skills, attention to detail, and effective communication help you excel in client interactions and multidisciplinary teams. These competencies ensure efficient, safe, and innovative cooling solutions that meet technical and regulatory requirements.

What are Cooling Engineers?

Cooling Engineers are professionals who design, install, maintain, and repair cooling systems, such as air conditioning and refrigeration units, for residential, commercial, and industrial settings. They ensure that cooling systems operate efficiently and safely, troubleshooting issues and performing routine maintenance as needed. Cooling Engineers often work with HVAC (heating, ventilation, and air conditioning) systems and must stay updated with industry standards and environmental regulations.

What are some typical challenges a Cooling Engineer faces when working on large commercial projects?

Cooling Engineers working on large commercial projects often encounter challenges such as integrating complex HVAC systems into existing infrastructure, ensuring energy efficiency while meeting regulatory standards, and coordinating with multiple stakeholders like architects and construction teams. Additionally, troubleshooting unexpected technical issues during installation or maintenance is common. Effective communication and adaptability are key, as project requirements and schedules can change rapidly.

What is the difference between Cooling Engineer vs HVAC Engineer?

AspectCooling EngineerHVAC Engineer
CredentialsBachelor's in Mechanical or Electrical Engineering, certifications like LEED or HVAC-specific licensesBachelor's in Mechanical or Electrical Engineering, HVAC certifications, licenses
Work EnvironmentDesigning and testing cooling systems, working in labs or on-site for cooling solutionsDesigning, installing, and maintaining heating, ventilation, and air conditioning systems
Industry UsageSpecialized in cooling systems for data centers, industrial cooling, or refrigerationBroader role covering heating, ventilation, and air conditioning across various buildings

Cooling Engineers focus specifically on designing and optimizing cooling systems, often in specialized environments like data centers or industrial facilities. HVAC Engineers handle a wider range of climate control systems, including heating and ventilation, across residential, commercial, and industrial settings. While both roles require similar technical credentials, their scope and application differ based on industry needs.

Job description

Job Posting Start Date 06-03-2026 Job Posting End Date 08-31-2026
At JetCool, a Flex company, we're at the forefront of liquid cooling innovation, delivering advanced solutions that empower our partners in AI and high-performance computing. United by a shared purpose, our teams are pushing the limits of what's possible and tackling complex challenges.
A career at JetCool offers the opportunity to make a real impact by helping build smarter, more sustainable data centers. Together, we're not just advancing technology - we're redefining cooling standards to create a more sustainable tomorrow.
Job Summary
JetCool, a Flex Company, delivers patented direct-to-chip liquid cooling solutions purpose-built for AI and high-density compute environments. Powered by JetCool's proprietary microconvective cooling technology and full-stack portfolio-from SmartPlates to Coolant Distribution Units (CDUs)-we enable leading processor and system designers to push performance, efficiency, and reliability to new limits.
The Pre-Sales Engineer based in either Littleton, MA, Austin, TX or Milpitas, CA serves as a technical advisor to customers requiring liquid cooled Cold Plates (SmartPlates) and Cooling Distribution Units (CDU), bridging thermal and mechanical engineering depth with clear, confident customer communication. This role owns pre-sales technical engagement ensuring JetCool solutions meet customer thermal performance and AI System and Rack integration needs. Success in this role requires the ability to communicate complex fluid-dynamics and heat-transfer Engineering analysis into concise, customer-ready explanations, while adapting technical depth in real time based on audience and context.
What a Typical Day Looks Like:
  • Lead technical discovery conversations to understand customer thermal requirements for AI Systems
  • Serve as the primary technical interface in customer engagements
  • Support sales engagements including RFP/RFQ responses and drafting content.
  • Gather the customer requirements and technical documents for Engineering to develop the liquid cooling solution
  • Partner with Engineering in understanding and communicating the liquid cooling solution
  • Evaluate AI system-level integration across cold plates, manifolds, CDUs, and rack-level cooling solutions
  • Develop and deliver technical presentations highlighting JetCool's technologies' differentiation
  • Present thermal technical analyses in a clear, customer-consumable format for both engineers and procurement managers
  • "Read the room" and adjust technical depth, pacing, and messaging based on audience feedback

The Experience We're Looking to Add to Our Team:
  • B.S. Mechanical Engineering
  • Foundation in fluid mechanics or heat transfer (experience with both preferred)
  • 3+ years of industry experience, including pre-sales, engineering, or customer facing technical roles
  • Experience working with fluid based mechanical designs
  • Strong communication and presentation skills
  • Exposure to CFD analysis tools (e.g., ANSYS, Icepak, FloTHERM) is preferred but not required
  • Apply fundamentals of fluid mechanics and heat transfer to help JetCool Engineering develop liquid cooling solutions to meet customer requirements is preferred

What you'll receive for the great work you provide:
  • Full range of medical, dental, and vision plans
  • Life Insurance
  • Short-term and Long-term Disability
  • Matching 401(k) Contributions
  • Vacation and Paid Sick Time
  • Tuition Reimbursement

Pay Range (Applicable to Massachusetts)
$110,100.00 USD - $151,400.00 USD Annual
