Firmware Engineering Intern, Winter 2026 at Mill

<div class="content-intro"><p><span style="font-weight: 400;">Mill is a waste prevention technology company reimagining what it means to eliminate waste, starting with food. We build smart systems and infrastructure for homes, businesses, and municipalities that transform food scraps from landfill-bound waste into valuable resources, including chicken feed. Tens of thousands of Mill’s residential food recyclers are already helping households divert millions of pounds of food scraps every year, paving the way for our upcoming launch of Mill Commercial—the industry’s first end-to-end solution for managing, understanding, and preventing food waste in commercial environments (e.g. grocery, restaurants, food services). At Mill, we are passionate about building easy-to-use, beautifully designed technologies that keep food in the food system and out of landfills.</span></p></div><p><span style="font-weight: 400;">As a Firmware Engineering intern at Mill, you’ll be working with a tight-knit, fast-paced team on a novel consumer product.
