Food waste dehydration hardware and software for residential and commercial markets

Environmental Services San Bruno, California 51–200 employees Privately Held

Mill manufactures connected food waste dehydrators—hardware running embedded C, FreeRTOS, and IoT protocols (WiFi, Bluetooth, GPIO, I2C, UART) paired with a full-stack web and mobile application (TypeScript, React, Vue, Python, Java on AWS). The company is actively scaling from residential to commercial deployment, with projects spanning hardware certification, dehydration platform refinement, and test automation infrastructure—a pattern reflected in heavy engineering hiring (9 of 19 open roles) skewed toward senior IC and lead-level positions, suggesting both product complexity and operational maturity challenges as they transition to manufacturing at scale.

About Mill

Mill produces food waste dehydrators designed for homes, workplaces, and municipal systems. The product combines proprietary embedded hardware (microcontroller firmware, power management, sensor integration) with cloud-connected software for monitoring, scheduling, and user engagement. The company operates a full engineering organization across firmware, backend systems (AWS infrastructure with Kinesis, Lambda, RDS, DynamoDB), and cross-platform frontends (web and iOS/Android apps). Current priorities include scaling commercial hardware production, improving reliability and test coverage in agile cycles, reducing per-unit costs, and optimizing energy efficiency—operational challenges typical of hardware-software crossover companies moving beyond early-stage validation into manufacturing and commercial deployment.
