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 software engineer in a start-up environment, you will draw on a broad set of technical and problem solving skills to build Mill’s flagship product and service offering. You will have the opportunity to work on every stage of product development, from initial design to implementation to scaling. You will design algorithms to solve novel, physical problems and use controlled testing and data analysis to optimize its performance.

As a founding member of the team, you will help build out best practices and procedures and influence our growing company’s culture and team. An ideal candidate loves seeking out new problems and devising creative solutions, regardless of technology. Ideal candidates are also as excited about working on sustainability as we are!

  • Strong collaboration skills
  • Strong written and verbal communication skills

Preferred Qualifications:

  • IOT experience a plus, especially working at the intersection of devices, mobile apps, and services on consumer devices
  • General knowledge of cloud providers (such as AWS or GCP) and related tools and ecosystems, especially around data pipelines and analysis.
