Summer 2026 Intern – Thermal & Mechanical Engineering
Location: Santa Clara, CA (On-site)
Team: Hardware Engineering / Systems Architecture
Dates: June 2nd - August 21st or June 22nd - September 11th
About the Role
At d-matrix, we are pushing the boundaries of AI compute efficiency. High-performance AI silicon generates significant heat, and our mission is to ensure our platforms remain cool and reliable under the most intense LLM inference workloads.
As a Thermal & Mechanical Engineering Intern, you will play a hands-on role in the physical realization of our hardware. You will transition between the CAD environment and the R&D lab, helping us build the infrastructure required to validate our next-generation liquid and air-cooled systems.
Key Responsibilities
- Lab Infrastructure & Setup: Assist in the foundational setup of the Thermal and Mechanical R&D lab. This includes organizing high-power test benches and installing specialized sensing equipment.
- Hardware Validation: Figure out and document the procedures to power and run PCIe accelerator cards in a standalone environment for thermal stress testing.
- Wind Tunnel Testing: Execute rigorous aerodynamic characterization using a wind tunnel. You will measure pressure drop and thermal performance across multiple PCIe cards to generate a high-fidelity statistical dataset for our architecture team.
- Thermal Modeling: Support the development of CFD (Computational Fluid Dynamics) models. Using Simcenter Flotherm, you will create detailed models of individual components (ASICs, VRMs, Optics) and full-system airflow profiles.
- Test Engineering: Prepare laboratory test setups and prepare test samples (including thermocouple attachment and TIM application) for thermal characterization.
- Documentation: Create "Gold Standard" documentation for laboratory procedures and maintain meticulous records of all experimental test data.
Required Qualifications
- Education: Currently pursuing a BS, MS, or PhD in Mechanical Engineering or a related field.
- CFD Foundations: Exposure to thermal simulation software (ideally Flotherm, Icepak, or SolidWorks Flow Simulation).
- Hands-on Aptitude: Comfort working with lab equipment, including thermal data loggers (DAQs), flow sensors, and high-power lab supplies.
- Analytical Mindset: Ability to take raw lab data and perform statistical analysis to identify performance trends and marginalities.
- Attention to Detail: Precision in laboratory work—from the exact placement of a thermocouple to the version control of a simulation model.
Preferred Skills
- Understanding of PCIe form factors and data center cooling requirements.
- Experience with 3D CAD modeling (SolidWorks, Pro/E, or NX).
- Familiarity with heat sink design and Thermal Interface Materials (TIM).
What You Will Gain
- End-to-End Experience: See a thermal design move from a Flotherm model to a physical wind tunnel test.
- Industry Impact: Contribute directly to the thermal integrity of hardware that will power the next generation of LLMs.
- Mentorship: Work side-by-side with senior hardware designers and architects who have built world-class systems at scale.

Get Access To All JobsTips for Finding J-1 Visa Sponsorship as a Mechanic
Verify your credentials match specialty occupation standards
J-1 Trainee programs for mechanics require documented post-secondary technical training or at least one year of work experience abroad. Gather transcripts, trade certificates, and employment letters before approaching any host employer or designated sponsor.
Target host employers with structured training programs
Automotive dealerships, fleet maintenance operations, and aerospace MRO facilities are more likely to fulfill the J-1 requirement of a formal Training Plan. Shops that already onboard apprentices or run manufacturer-certified service programs are your strongest targets.
Search for J-1 compatible roles on Migrate Mate
Use Migrate Mate to filter U.S. mechanic and technician roles by employers with demonstrated sponsorship history. This narrows your search to host organizations already familiar with the DS-2019 process and Training Plan obligations.
Distinguish your Trainee category from the Intern category
If you are currently enrolled in a technical school or vocational program, you qualify as a J-1 Intern. If you have already graduated, you fall under the Trainee category, which has different duration limits and requires at least one year of prior relevant experience.
Confirm your host employer will complete the Training Plan
Before accepting any offer, ask whether the employer will co-sign a formal Training or Internship Placement Plan. Without this document, your designated sponsor cannot issue a DS-2019, and no J-1 status can begin. Many smaller shops decline this obligation.
Understand the two-year home residency rule before filing
Some J-1 Trainee participants are subject to a two-year home-country residency requirement before changing to certain other visa statuses. Check with your designated sponsor early, as your country of funding or citizenship may trigger this requirement.

Find Mechanic JobsMechanic J-1 Visa: Frequently Asked Questions
Which J-1 program category applies to mechanic roles?
Most mechanics enter under the J-1 Trainee category if they have completed their technical or vocational training and hold at least one year of relevant work experience abroad. Current students in automotive or mechanical programs who have not yet graduated may qualify under the J-1 Intern category instead. The distinction affects duration limits and eligibility requirements, so confirm your category with a State Department-designated sponsor before pursuing host employers.
Who actually sponsors the J-1 visa for a mechanic position?
The visa sponsor is a U.S. Department of State-designated organization, such as Cultural Vistas or AIPT, not your employer. The employer is the host, meaning they provide the work environment and co-sign the Training Plan. The designated sponsor reviews your qualifications, issues the DS-2019 form, and monitors program compliance throughout your stay. You must be accepted by a designated sponsor before you can apply for the J-1 visa at a U.S. consulate.
How do I find host employers open to J-1 mechanics?
Migrate Mate lets you search U.S. mechanic and technician roles filtered by employers with sponsorship history, which helps you identify host organizations already comfortable with the J-1 process. Look for automotive dealerships, fleet operators, and aerospace maintenance facilities, since these businesses frequently run structured training environments that satisfy the formal Training Plan requirement that designated sponsors need before issuing a DS-2019.
Does the J-1 Trainee program have a duration limit for mechanics?
Yes. J-1 Trainee programs are capped at 18 months in total, with no renewals available in the same occupational category with the same sponsor. J-1 Intern programs are limited to 12 months. Unlike the H-1B, the J-1 has no annual lottery or numerical cap, but these fixed duration limits mean you and your host employer need to plan your training objectives carefully from the start.
Can a small auto repair shop host a J-1 mechanic trainee?
It depends on whether the shop can produce and administer a formal Training or Internship Placement Plan that maps specific skills to a weekly schedule. Designated sponsors require this document to issue the DS-2019, and many small independent shops lack the administrative capacity to create or maintain it. Shops affiliated with manufacturer service networks, dealership groups, or fleet operators tend to have the structure sponsors require and are more realistic host employer targets.
