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.

At Arista, we take pride in our track record of success and strive to maintain the highest standards of quality and performance in everything we do.

Job Description

This is a highly technical engineering role focused on overseeing the process of  taking new liquid cooled products from design to full scale manufacturing.  This role requires a combination of technical expertise in electro/mechanical design and manufacturing, along with recent experience in liquid cooled products and the thermal solutions that make them possible.

Who You'll Work With

As a Mechanical NPI Liquid Cooling Engineer, you will engage with our Mechanical and Thermal Engineering teams, collaborating closely with Engineering Cross-Functional team members, supplier management and our CM partners manufacturing the cooling solutions, and the assembly of our products. In this capacity, you will work with Hardware and Mechanical Engineering technical leaders to advance product development, manufacturing, and supplier strategies for High-Performance Networking equipment. Your role will bridge design review, Manufacturing NPI and Production, ensuring a seamless transition from conceptualization to high-volume scaled manufacturing. The CMs you will engage with specialize in areas such as metals, plastics, die casting, high-speed cables, air and liquid cooling thermal solutions, optics and fiber connectivity, and numerous other E/M suppliers who manufacture key components of our products, in addition to direct collaboration with our customers.

What You'll Do

You will assume a pivotal role in leading and developing a high-performing team responsible for introducing new products to market, with a strong emphasis on manufacturability, reliability, efficiency, and quality. You will provide technical leadership while fostering cross-functional collaboration among engineering, supply chain, quality, and manufacturing teams. Furthermore, you will engage directly with our customers, addressing matters ranging from defining product requirements to resolving any field quality escalations that may arise.

You will also be responsible for developing and optimizing manufacturing processes, ensuring product quality, and driving continuous improvements. This role necessitates robust expertise in E/M Manufacturing, Design for Cost and Manufacturability (DFM) considerations. The ideal candidate will influence engineering teams, collaborate with cross-functional groups, and implement process improvements to enhance efficiency and scalability.
