Job description

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.

• Implementing prototype drivers and testing on hardware systems.

Minimum Qualifications

• BS, MS or PhD in Electrical Engineering, Computer Science, Computer Engineering (obtained)

• Strong analytical and communication skills

Preferred Qualifications

• Experience with embedded Linux systems: Yocto preferred
• Experience debugging physical hardware using oscilloscopes, network/logic analyzers
• Experience with python scripting
• Experience with Hardware-in-the-Loop testing platforms
