Product Design Engineering Intern, Fall 2025

Mill is all about answering a simple question: how can we prevent waste? Less waste can save time, money, energy, maybe even our planet. And there’s no better place to start than food. Food waste is one of the most solvable climate problems facing us today. Plus, our trash really stinks. It’s gross, heavy, and our least favorite chore. At Mill we are striving to build a better environment for all, as we take on climate and kitchen change.

As a Product Design Engineering intern at Mill, you’ll be working with a tight-knit, fast-paced team on a novel consumer product. Your day-to-day will include hands-on work with hardware components and lab equipment as well as CAD design tools like NX. Since we’re a small team, your work and learning will span design, tooling, and testing as we push towards launch. This internship is for someone who wants to learn and be creatively challenged.

Responsibilities

• Work closely with the Mill cross functional team on the design and validation of new products.
• Develop prototypes and execute tests in order to drive design towards mass production maturity.
• Support 3D CAD design and 2D documentation.
• Support engineering build activities, partnering with suppliers and CMs to troubleshoot and resolve manufacturing quality issues.

Minimum Qualifications

• BS, MS or PhD in Mechanical Engineering (obtained or in progress)
• Working knowledge of manufacturing processes and material selection for the design and development of electro-mechanical systems.
• Proficient in 3D CAD (prefer Nx).
• Proficient in a variety of rapid prototyping methods.
• Strong analytical and communication skills.

Preferred Qualifications

• Experience with simulation tools (FEA and thermal) and statistical analysis methods.
• Experience with designing for high volume manufacturing (DFM/DFA).
