Lead Hardware Systems Engineer

Mill is a waste prevention technology company reimagining what it means to eliminate waste, starting with food. We build smart systems and infrastructure for homes, businesses, and municipalities that transform food scraps from landfill-bound waste into valuable resources, including chicken feed. Tens of thousands of Mill’s residential food recyclers are already helping households divert millions of pounds of food scraps every year, paving the way for our upcoming launch of Mill Commercial—the industry’s first end-to-end solution for managing, understanding, and preventing food waste in commercial environments (e.g. grocery, restaurants, food services). At Mill, we are passionate about building easy-to-use, beautifully designed technologies that keep food in the food system and out of landfills. About this Role: As a Lead Systems Engineer at Mill, you will be responsible for helping ideate, test and define the next generation of Mill’s commercial food recycler technology. We are a small team and you will work cross-functionally with Electrical/Mechanical Engineers, Algorithms and Product Teams to deliver world class industrial products designed to keep food waste out of landfills. This is a hands-on role and best suited for someone who has a history of working on interdisciplinary projects involving thermal, fluids or chemical processes from concept through production. Responsibilities: Owns system performance: Tech lead for test engineers on the experimental optimization and characterization of system parameters such as temperatures, flow rates, and heat transfer to improve energy efficiency and throughput. Collaborates on analysis and helps derive conclusions and next steps from experimental data. Work collaboratively with algorithms and firmware teams to develop control schemes for the system processes to optimize energy consumption and drying time while ensuring reliable function Identify opportunities to improve the system design to deliver improved performance or reliability. Oversee and direct external simulations work such as CFD, thermal and multiphysics models to help improve system design and performance. Determine the system requirements for various components such as fans, condensers, heaters, flow meters and sensors. Collaborates with other systems engineers to ensure these are well documented and have visibility to other stakeholders. Collaborate with mechanical engineers to optimize custom hardware such as mixing paddles, air deflectors and cutting/shredding technology core to the drying and grinding chamber. Collaborate with operations and global supply chain managers on sourcing components that will meet our specifications at production volumes. Collaborate with mechanical engineers to facilitate the transition of prototype parts and bench top proof of concept to high volume manufacturing methods. Qualifications: 5+ years experience working hands on as a systems or in a lead role with significant thermal and fluid handling aspects. Ideal past experience would include taking new processes from concept through to production. An ability to work cross functionally, and interface with a wide range of disciplines to enable cross functional collaboration. Strong communications skills through written, verbal and graphical presentation techniques. Ability to leverage python to analyze time series data is preferred, but other means (R, Ai ect) are also acceptable. Past experience managing cross functional engineering projects spanning a number of technical disciplines including electrical, mechanical, thermal, and controls. Hands-on experience with electromechanical integration and part selection such as blowers, valves, fans and sensors BS and or MS degree in related engineering field preferably with focus on Process, Thermal, mechanical or Chemical Engineering. Masters or higher is preferred. Some prior startup experience is highly preferred. Strong communications skills through written, verbal and graphical presenta
