Thermal Engineer – Liquid Cooling

Location: On-site in Santa Clara, California, United States

Salary: $200,000–$250,000 base salary plus equity

Company

Develops high-performance hardware for advanced data-center applications.

What you will do

• Design heat sinks, cold plates, liquid-cooling loops, and advanced air-, liquid-, and two-phase-cooling solutions.
• Develop thermal models and simulations, then conduct physical testing, validation, and model correlation.
• Integrate cooling systems into broader hardware architectures and troubleshoot thermal-performance and reliability issues.
• Collaborate with mechanical, electrical, and systems-engineering teams.
• Build technical relationships with cooling-component suppliers and evaluate emerging thermal technologies.

Requirements

• Bachelor’s degree in Mechanical Engineering or a related discipline; a master’s degree is preferred.
• 10+ years of thermal-design experience, including at least two years designing liquid- or two-phase-cooling systems.
• Strong knowledge of heat-transfer fundamentals and experience taking thermal designs from modeling through physical validation.
• Proficiency with Flotherm, Flotherm XT, FloEFD, Icepak, or equivalent thermal-analysis tools.
• Experience designing cooling solutions for high-power commercial electronic systems.
• Understanding of data-center liquid-cooling systems, including in-chassis loops, rack interfaces, coolant distribution units, and facility-side connections.

Nice to have

• Experience with networking, server, telecom, or comparable high-power rack-mounted equipment.

Culture & Benefits

• Work within an experienced team developing next-generation data-center hardware.
• Opportunity to own technically challenging thermal systems from early analysis through system integration.
• Equity included in the compensation package.
