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 firmware engineering intern at an early stage start-up, you’ll be working with a tight-knit, fast paced team on a novel consumer product.  You will have the opportunity to learn about all aspects of consumer product design and manufacture and work on firmware features, tooling, and testing as the team works towards our first launch!  You will work hands-on with hardware and lab equipment as well as embedded C code.


  • Bring-up, prototype, and validate device components like sensors and actuators
  • Implement features and tests to produce well-tested, robust code
  • Interface with QA and hardware teams to support engineering validation
  • Identify and troubleshoot issues from firmware all the way to the hardware
  • Analyze device metrics to improve code structures and algorithms 

Minimum Qualifications:

  • Pursuing Bachelor’s or Master’s degree in Electrical Engineering, Computer Science, Mechanical Engineering, or a related field
  • Strong C/C++ programming skills
  • Embedded device experience (e.g. arduino, microcontroller, etc.)
  • Experience with version control using Git

Preferred Qualifications:

  • One or more embedded software domain knowledge, such as:
  • Microcontroller architecture like ARM Cortex-M, ESP32 etc.

An Insider's view of Mill

What’s the vibe like in the office?

I think of our company virtue, Levity. There’s a high concentration of tie-dye, Slack huddles, brainstorming in the office, whiteboard sessions, puns and jokes. You can hear someone laughing somewhere at least once a day.


Electrical Engineer

What projects are you most excited about?

Creating a personality for Mill. There are no preconceived notions of who Mill is yet, we get to define it, that’s incredibly exciting.


Social Media Marketing

How do you empower your team to be more creative?

We give each other permission to be elastic, to bounce back, to grow and notch forward. And delightfulness is everywhere – in the product, in our office, even in our naming conventions. The branding in surprise locations really solidifies the spunkiness of our brand…and the team!


Hardware Program Management

How does your team reward individual success?

In large corporations, you can be siloed off into specific tasks and you never see the end product of your work. At Mill, you start with a problem that you’ve identified, brainstorm a solution, bring it to life and test the solution; you get to see the end result of your work.
