AI-powered wearable hardware with custom embedded OS and inference stack
Sesame is building consumer wearables with on-device AI, running a custom RTOS + embedded OS (Zephyr, FreeRTOS) paired with inference acceleration (vLLM, SGLang, PyTorch, JAX, TensorFlow). The stack reveals a company solving real-time ML inference at the edge: they're adopting NetSuite and SAP to manage hardware supply chains while grappling with model initialization latency, audio pipeline optimization, and sensor integration at scale. Engineering dominates the org (38 roles open), with active hiring in Taiwan signaling manufacturing readiness for volume production.
Sesame designs and manufactures AI wearable devices aimed at consumer markets. Founded in 2023 and based in San Francisco with ~80–130 employees, the company operates a vertically integrated hardware stack spanning custom OS development, on-device inference, sensor integration, and firmware. Active projects span product development, embedded OS customization for real-time AI workloads, manufacturing test strategy, and supply chain readiness. The hiring mix—weighted heavily toward engineering and hardware roles, with active recruitment in the US and Taiwan—indicates a company moving from prototype toward production manufacturing at scale.
vLLM, SGLang, PyTorch, JAX, and TensorFlow. These sit atop a custom embedded OS built on Zephyr and FreeRTOS to enable real-time AI inference on wearable devices.
Reducing model initialization times and scaling real-time inference workloads while integrating complex sensing systems—all within tight timelines for mass production.
