Electrical Engineer

Mill; San Bruno (CA); On-site; USD 155,000 - 195,000; Full time

Job summary

Mill is a waste prevention technology company reimagining how to eliminate waste, starting with food. As an Electrical Engineer, you will own the power, sensing, and control layer of our hardware, driving designs from schematic capture through DVT closure and production transition.

You will lead production-intent electrical design, design multi-rail power architectures, and collaborate cross-functionally to ensure reliable hardware in real kitchens. Strong hands-on hardware skills are essential.

Qualifications

• BS or MS in Electrical Engineering, Computer Engineering, Mechatronics, or equivalent.
• 4+ years of hands-on experience on production hardware products.
• Proficient in schematic capture and PCB layout in Altium or equivalent.
• Experience with microprocessors, sensor integration, motor control, and embedded systems.
• Comfort working with AC power systems and safety considerations.
• Able to independently bring up and debug new hardware; bench proficiency with oscilloscopes, logic analyzers, power supplies, multimeters, thermal imaging, and data acquisition; hands-on with PCB rework and cable assembly.
• Strong communicator; able to operate in ambiguous problem spaces and drive closure with limited oversight.

Responsibilities

• Lead board bring-up, validation, and rework tracking; debug and root-cause issues across circuits, firmware integration points, and full-system behavior.
• Own production-intent electrical design - schematic capture, PCB layout, component selection, and DFM.
• Design and validate multi-rail power architectures.
• Design and implement sensing and mechatronic platforms.
• Design with certification in mind (UL, ETL, FCC, EU, Canada).
• Contribute to design reviews, EVT/DVT/PVT readiness, and the transition from prototype to production.
• Partner cross-functionally with mechanical, firmware, controls, science, operations, and product teams to make architecture and tradeoff decisions.
• Support relationships with ODMs, CMs, PCB fab/assembly vendors, and component distributors; contribute to component sourcing, alternates qualification, and DFM feedback.

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. 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 an Electrical Engineer at Mill, you will own the power, sensing, and control layer of our hardware - the systems that keep the product working reliably in real kitchens. You'll carry designs from schematic capture through DVT closure and production transition, working hands-on alongside mechanical, firmware, and systems engineers to root-cause issues across circuits and full-system behavior

Responsibilities:

• Lead board bring-up, validation, and rework tracking; debug and root-cause issues across circuits, firmware integration points, and full-system behavior
• Own production-intent electrical design - schematic capture, PCB layout, component selection, and DFM
• Design and validate multi-rail power architectures
• Design and implement sensing and mechatronic platforms
• Design with certification in mind (UL, ETL, FCC, EU, Canada)
• Contribute to design reviews, EVT/DVT/PVT readiness, and the transition from prototype to production
• Partner cross-functionally with mechanical, firmware, controls, science, operations, and product teams to make architecture and tradeoff decisions
• Support relationships with ODMs, CMs, PCB fab/assembly vendors, and component distributors; contribute to component sourcing, alternates qualification, and DFM feedback

Qualifications:

Required

• BS or MS in Electrical Engineering, Computer Engineering, Mechatronics, or equivalent
• 4+ years of hands-on experience on production hardware products, with demonstrated end-to-end ownership through bring-up and validation
• Proficient in schematic capture and PCB layout in Altium or equivalent
• Solid experience with microprocessors, sensor integration, motor control, and embedded systems
• Comfort working with AC power systems and an understanding of relevant safety considerations
• Able to independently bring up and debug new hardware; strong bench proficiency with oscilloscopes, logic analyzers, power supplies, multimeters, thermal imaging, and data acquisition; hands-on with PCB rework and cable assembly
• Strong communicator; able to operate in ambiguous problem spaces, synthesize requirements, and drive closure with limited oversight

Preferred

• Scripting proficiency in Python and embedded C/C++ for test automation, data analysis, and prototype firmware
• High-power appliance, commercial equipment, or industrial product development experience
• Safety certification experience (UL, ETL, FCC, CE, IC) - including pre-compliance testing, EMI debug, and cert lab management
• Thermal system design - component derating, temperature sensing and control, PCB layout for heat dissipation, and heatsink selection
• Designing interlock and safety architectures for certified appliances
• Industrial communication protocols (Modbus, RS-485, CAN)
• Experience with Jetson, Raspberry Pi CM, or other embedded compute platforms integrated into hardware systems
• Startup experience preferred

The estimated base salary range for this position is $155 to 195K, 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.
