About The Position

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. We’re looking for a hands-on Senior Cloud Engineer to lead our Cloud work across our AWS infrastructure. This role is responsible for designing, building, and maintaining our end-to-end applications across web, mobile, cloud, and data that support our customer experiences. In this role, you'll work with a cross functional group of engineers, guide architectural decisions, and help scale products that are critical to our success and growth.
