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.

Our small, nimble IoT services and mobile team is passionate about developing well-designed, scalable software to deliver a delightful, feature rich experience to our customers and internal teams. The team owns Mill’s customer-facing mobile app and the backend services that interface with the mobile app, bin, and data warehouse. We also automate manual tasks to increase the velocity of other Mill teams! We believe in leveraging off the shelf components for solved problems and building custom components to solve difficult and differentiating challenges.

We are seeking an engineering manager with excellent technical judgment, who can make high level architecture decisions and is as comfortable building and testing new features, as driving a high performance team. An ideal candidate will bring a broad set of problem solving skills and relish opportunities to solve novel problems with whatever tool is best for the job.

We work closely with product managers, other engineering teams, and testers to devise elegant user experiences and scale reliable stacks with Mill’s rapid growth! We are also iterating on our development process as the team grows, so it’s important that candidates are invested in continuous improvement of process and best practices.

Of course, we hope you are as excited to work on sustainability as we are!
