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.

  • Generate detailed CAD models, specifications and documentation
  • Prototype, test and analyze component and system designs
  • Validate part and system performance and iterate designs to achieve targets
  • Create predictive models and correlate with real world performance
  • Perform root cause analysis of performance failures and drive corrective actions
  • Work directly with the Operation team, suppliers and CM partners to ensure parts are properly manufactured and assembled

The estimated base salary range for this position is $138k to $180k, which does not include the value of benefits or a potential equity grant. A wide range of factors are considered in making compensation decisions, including but not limited to skill sets, market conditions, experience and training, licensure and certifications, and business and organizational needs. At Mill, it is not typical for an individual to be hired at or near the top of the range for their role.
