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 one of the first members of the team, you will have greenfield opportunities to design and build technology supporting our first product and service offering from scratch.

You will have the opportunity to work on every stage of product development, from initial design to implementation to scaling. You will work closely with UX designers, product managers, and testers to devise elegant user experiences and bring our team’s long term vision to life! While we are looking for developers comfortable with both backend and frontend development, we’d still love to chat if you lean heavily to one side or the other!

You will help build out best practices and procedures and influence our growing company’s culture and team. An ideal candidate loves proactively seeking out problems and devising creative solutions, regardless of technology. We also hope you are as excited about working on sustainability as we are!
