These skills and qualities are important to ensure interns can support engineering teams, apply theory to real-world challenges, and grow within the profession.

What does a mechanical engineering intern do?

As a mechanical engineering intern, you prepare calculations and reports, gain experience with engineering systems, integrate tracking plans, and perform analysis of mechanical design choices. You may help test products, interact with various members of a project team, and create or modify CAD models. As an intern, your responsibilities are limited, and most employers consider gaining experience to be the most important part of your job. Many mechanical engineering interns focus on building professional relationships in the hope of landing a permanent job after graduating. You may need to develop your skills in engineering, CAD software, and prototyping during your internship.

What types of projects do mechanical engineering interns typically work on, and how much hands-on experience can I expect?

As a Mechanical Engineering Intern, you'll often assist with a mix of design, analysis, and testing projects under the guidance of experienced engineers. Interns commonly use CAD software to create or modify designs, help with prototype assembly, perform basic calculations, and assist in conducting experiments or tests. You can expect significant hands-on experience, especially in labs or on the shop floor, learning how theoretical concepts are applied in real-world engineering tasks. Collaboration with cross-functional teams, such as manufacturing or quality assurance, is typical, providing valuable exposure to the entire product lifecycle.

Which internship is best for mechanical engineering students?

The best internship for mechanical engineering students typically involves roles in manufacturing, design, or research and often requires proficiency in CAD software, problem-solving skills, and understanding of engineering principles. Internships at manufacturing firms, automotive companies, or aerospace organizations provide practical experience and industry exposure valuable for career development.

What does a mechanical engineering intern do?

A Mechanical Engineering Intern assists engineers in designing, developing, and testing mechanical devices and systems. They typically work on tasks such as creating CAD drawings, conducting research, performing calculations, and helping with prototype assembly or testing. Interns gain hands-on experience by supporting ongoing projects and collaborating with other engineers and technicians. This role provides valuable exposure to real-world engineering challenges and helps students apply their academic knowledge in a practical setting.

Job description

Thermal/Mechanical Engineer

Location: California
Reports To: Vice President, Systems Engineering
Salary Range: $150,000 – $170,000

Overview

We are seeking a highly skilled Thermal/Mechanical Engineer to join a leading engineering team in the development of innovative thermal solutions for memory and storage products. This role will play a critical part in shaping next-generation technologies that support AI, cloud computing, and enterprise infrastructure.

Position Summary

The Thermal/Mechanical Engineer will design, model, and validate advanced thermal solutions for high-performance memory and storage hardware used by top-tier OEMs, ODMs, and hyperscale clients. The ideal candidate will combine deep technical expertise with hands-on design and problem-solving skills.

Key Responsibilities

  • Create mechanical and thermal models of electrical and mechanical assemblies using CAD files or from scratch.

  • Design or source thermal solutions for advanced memory and storage products.

  • Run simulations to validate that thermal designs meet specified requirements.

  • For custom solutions, specify required materials and prepare detailed fabrication and assembly drawings.

  • Develop and implement Design of Experiments (DoEs) to evaluate thermal properties of assemblies.

  • Collaborate with electrical engineering teams, providing feedback and design suggestions.

  • Generate assembly drawings and ensure proper documentation of assembly processes.

  • Partner with manufacturing to guarantee assemblies are built to specifications.

Qualifications

  • Bachelor’s or Master’s degree in Mechanical Engineering, Thermal Engineering, or a related field.

  • 8+ years of industry experience in IC packaging design, thermal, or mechanical engineering.

  • Proficiency in mechanical drawing tools such as AutoCAD and SolidWorks.

  • Experience with thermal analysis and simulation tools such as Flowtherm or Icepak.

  • Familiarity with thermal interface materials (heat sinks, spreaders, greases, gap pads, etc.) is desirable.

  • Strong problem-solving abilities, attention to detail, and ability to innovate.

  • Excellent communication skills, professionalism, and ability to work cross-functionally.

  • Proven stakeholder management and influencing skills.

  • Knowledge of memory and storage components (DDRx, LPDDRx, NAND) and modules (DIMMs, SSDs, etc.) is highly desirable.

  • Willingness to travel occasionally (less than 10%).

Why This Role Stands Out

  • Work on cutting-edge thermal solutions powering the next generation of computing and storage.

  • Collaborate with world-class engineers in a fast-paced, innovative environment.

  • Competitive salary and growth potential.
