Thermal Design Engineering Intern (SI Hardware)

Quick Facts

• Role: Thermal Design Engineering Intern (SI Hardware)

• Expected start: Around January 2027

• Duration: Through the Spring term (approximately May 2027 or later, if available)

• Schedule: Minimum 12 weeks, Full-Time (40 hours/week), on-site

Description

Join the SI Hardware team to design and validate air and liquid cooling solutions for high-density SI data centers powered by Dojo. The internship includes CFD-based thermal/fluid modeling, evaluation of advanced cooling technologies, first-principles thermal/mechanical simulations, and validation support for low-voltage electronic systems. You will collaborate cross-functionally across the system design—from chip package and PCBs to trays, racks, and infrastructure—and communicate results via documentation and presentations.

Responsibilities

• Perform CFD modeling of heat transfer and fluid flow for SI hardware cooling

• Support evaluation of new cooling technologies (TIMs, heat spreaders, coldplates)

• Conduct thermal and mechanical first-principles analysis and simulations

• Test and validate electronic systems across all low-voltage electronics

• Support manufacturing lines and test engineers to quickly identify issues, resolve problems, and develop production solutions

• Create clear documentation and presentations to communicate concepts, designs, and findings

Requirements

• Actively pursuing a degree in Mechanical Engineering or a thermals-related field (graduation between May 2027 – December 2027)

• Strong understanding of heat transfer, thermodynamics, and fluid dynamics fundamentals

• Experience with CFD and developing numerical models of thermal/fluid systems

• Hands-on experience with mechanical or thermal testing and data analysis

• Passion for electro-mechanical product design and creative problem solving for mechanical/thermal challenges

• Strong teamwork, communication, and presentation skills

• Ability to work 40 hours/week on-site for at least 12 weeks (start around January 2027)

Benefits

• Medical plans with plan options and $0 payroll deduction

• Family-building, fertility, adoption and surrogacy benefits

• Dental (including orthodontic) and vision plans, with an option for $0 payroll contribution

• Company-paid HSA contribution when enrolled in the High Deductible Medical Plan with HSA

• Healthcare and Dependent Care Flexible Spending Accounts (FSA)

• 401(k), Employee Stock Purchase Plans, and other financial benefits

• Company-paid Basic Life, AD&D, and short-term disability insurance

• Employee Assistance Program

• Sick and Vacation time (Flex time for salary positions) and paid holidays

• Back-up childcare and parenting support resources

• Voluntary benefits (critical illness, hospital indemnity, accident insurance, theft & legal services, pet insurance)

• Commuter benefits; employee discounts and perks program

• Earned Wage Access: real-time pay access paid daily (subject to eligibility and schedule)

• Expected compensation: $20.00–$65.00 + benefits (varies based on market location and job-related skills/experience)
