About the role
Design and develop thermal solutions (air cooled or liquid cooled) for systems with high-power ASICs and high-density optical transceivers. Develop detailed package, board, and system level simulations using Computational Fluid Dynamic tools such as Flotherm or Icepak to simulate and analyze thermal solutions.
What they're looking for
- Bachelors in Mechanical or Thermal Engineering + 12 years of related experience, or Masters in Mechanical or Thermal Engineering + 8 years of related experience, or PhD in Mechanical or Thermal Engineering + 5 years of related experience
- 5+ years of experience in design, simulation, and testing of thermal solutions for electronic devices and systems
- 3+ years of relevant experience in the thermal design of telecom, compute, or networking equipment
- Experience in use of Computational Fluid Dynamic analysis tools such as Flotherm or Icepak
- Knowledge and experience with advanced air-cooling technologies (vapor chamber and remote heat sinks, thermal interface materials, fans/fan trays)
- Experience with designing liquid cooling and/or immersion cooling systems
