At JetCool a Flex company were 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 whats possible and tackling complex challenges.

A career at JetCool offers the opportunity to make a real impact by helping build smarter more sustainable data were not just advancing technology were redefining cooling standards to create a more sustainable tomorrow.

To support our extraordinary teams who build great products and contribute to our growth were looking to add a Principal Thermal Mechanical Engineer located in Littleton MA.

Reporting to the Product Manager the Principal Thermal Mechanical Engineer will play a pivotal role in the early phases of product development and serving in a guidance capacity through product maturation. Our products drive sustainability across the data center infrastructure by allowing higher coolant temperatures and by driving more complete heat capture for liquid cooling. The Principal Mechanical Engineer will provide technical leadership mentorship and hands-on expertise in mechanical design fluid dynamics and heat transfer but also work closely with customers in communicating the art of the possible with JetCool technology and building a strong customer relationship on a technical level.

What a typical day looks like:

• Lead the initial design analysis and optimization of complex fluid systems from concept initial CAD to final detailed CAD and drawing for liquid cooling including cold plates pumps fluids tubing and heat exchangers for the latest computer processing chipsets.
• Collaborate with customer and partner teams to integrate fluid systems into overall product designs.
• Conduct fluid flow simulations analyses and tests to ensure efficient and reliable performance of fluid systems under various operating conditions.
• Perform detailed calculations and analysis of fluid dynamics pressure drops thermal performance and material compatibility.
• Develop and review engineering specifications and documentation for fluid system and heat transfer components and assemblies ensuring compliance with industry standards and regulatory requirements.
• Assist in maintaining a strong best practice culture and driving additional foundational knowledge and IP through research.
• Identify technical gaps to advocate for research and development and lead research projects maximizing product impact and benefit.
• Provide technical guidance and mentorship to junior engineers fostering a culture of continuous learning and development.
• Participate in design reviews presenting technical findings and recommendations to internal and external stakeholders.
• Contribute to the development of new product concepts and innovations in fluid system design keeping abreast of industry trends and emerging technologies.
• Support the resolution of technical challenges and issues related to fluid systems throughout the product lifecycle.

The experience were looking to add to our team:

• Masters (Thesis required) degree in Mechanical Engineering or related field.
• Minimum of 7 years of post-collegiate experience in designing and engineering fluid systems preferably within the data center thermal management/ cooling automotive medical or nuclear industries.
• Minimum of 3 years working at senior or principal engineer level in an industrial setting.
• Profound expertise in fluid dynamics thermodynamics and heat transfer with a strong foundation in engineering principles.
• Extensive experience in SolidWorks CAD complex part and assembly drawings GD&T and DFMs.
• Ability to independently develop product concepts performance analysis and design experiments. Track record of new product development preferably thermal fluid products.
• Strong analytical and problem-solving skills with the ability to effectively troubleshoot and optimize fluid system performance.
• Excellent communication and documentation skills to convey complex technical concepts to both technical and non-technical audiences.
