What are the key skills and qualifications needed to thrive as an Internship Thermal Engineer, and why are they important?

To thrive as an Internship Thermal Engineer, you typically need foundational knowledge in thermodynamics, heat transfer, and fluid mechanics, usually gained through a degree in mechanical or a related engineering field. Familiarity with simulation software such as ANSYS, MATLAB, or SolidWorks, and an understanding of CAD tools are commonly required, while relevant coursework or certifications can be beneficial. Strong analytical thinking, problem-solving abilities, and effective communication skills help interns collaborate and present findings clearly. These abilities ensure accurate analysis, efficient teamwork, and valuable contributions to thermal engineering projects.

What does an Internship Thermal Engineer do?

An Internship Thermal Engineer assists senior engineers in designing, analyzing, and testing thermal systems and components. Their tasks often include running simulations, conducting experiments, collecting data, and helping to improve cooling or heating solutions for various products. Interns typically work in industries such as aerospace, automotive, electronics, or energy, gaining hands-on experience with thermal management techniques and tools. This role is ideal for engineering students who want to apply their theoretical knowledge to real-world challenges while developing technical and teamwork skills.

What types of projects and responsibilities can I expect as an Internship Thermal Engineer?

As an Internship Thermal Engineer, you will typically assist in designing, analyzing, and testing thermal systems or components under the supervision of senior engineers. Your daily tasks may include running simulations, collecting and interpreting temperature data, preparing reports, and collaborating with cross-functional teams such as mechanical design or manufacturing. Interns often get exposure to real-world problem-solving and are encouraged to contribute ideas during team meetings. This hands-on experience not only builds technical skills but also provides insight into the workflow and challenges faced in thermal engineering roles.

What is the difference between Internship Thermal Engineer vs Thermal Engineer?

AspectInternship Thermal EngineerThermal Engineer
CredentialsEnrolled in or recent graduate of engineering programBachelor's or higher in Mechanical or Thermal Engineering
Work EnvironmentInternship setting, entry-level projectsFull-time professional role, project leadership
ResponsibilitiesAssisting with thermal analysis, learning proceduresDesigning thermal systems, conducting analyses, troubleshooting
Industry UsageInternship programs, training rolesDesign firms, manufacturing, aerospace, automotive

The main difference between an Internship Thermal Engineer and a Thermal Engineer is experience level and responsibilities. Internships are designed for students or recent graduates gaining practical experience, while Thermal Engineers are full-time professionals responsible for thermal system design and analysis. Internships serve as a stepping stone toward becoming a full Thermal Engineer.

Job description

About Etched

Etched is building hardware for frontier intelligence. We co-design chips, racks, software, and manufacturing to deliver best-in-class throughput and latency across both prefill and decode workloads. Our first products are heavily focused on inference. Backed by hundreds of millions from top-tier investors and staffed by leading engineers, Etched is redefining the infrastructure layer for the fastest growing industry in history.

Job Summary

Our mechanical/thermal engineering interns will work within the mechanical and thermal engineering organization, with a strong focus on NPI prototyping, manufacturing fixture development, liquid cooling technologies and rack-level system development

Our Platform Team is building the full-stack system that supports Etched Silicon from PCB to Rack. We are seeking interns to work across all aspects of mechanical and electrical engineering to design the future of high power ASIC systems. We are looking for Summer '26, Fall '26, Spring '27, and Summer '27 interns.

You may be a good fit if you have

  • Progress towards a Bachelor’s or Master’s in Mechanical Engineering, Computer Engineering, or related field

  • Experience building real mechanical systems, boards, or other hands-on projects.

  • Knowledge of board design cycle, high-speed interconnects, power delivery, and system integration.

We encourage you to apply even if you do not believe you meet every qualification.

Program details:

  • 12-week paid internship

  • Generous housing support for those relocating

  • Daily lunch and dinner in our office

  • Based at our office in San Jose, CA

  • Direct mentorship from industry leaders and world-class engineers

  • Opportunity to work on one of the most important problems of our time

How We're Different
Etched believes in the Bitter Lesson. We are the first inference-focused frontier AI system, betting early on transformer and transformer-like architectures and on increasing model sizes. Our addressable market is the entirety of inference, unlike many of our competitors.


We are a fully in-person team in San Jose (Santana Row), and greatly value engineering skills. We do not have boundaries between engineering and research, and we expect all of our technical staff to contribute to both and work across disciplines as needed..
