About the Role

Join a fast-moving hardware team building the firmware for a next-generation consumer wearable platform. This founding-level embedded engineering role involves defining firmware architecture and guiding a category-defining device from prototype to mass production, covering low-power embedded design, biometric sensor integration, BLE connectivity, and production engineering.

Responsibilities

• Architect and develop embedded firmware for battery-powered wearable devices.
• Own core systems for low-power wireless connectivity, sensor processing, and data pipelines.
• Design and optimize Bluetooth Low Energy (BLE) connectivity for ultra-low-power operation.
• Build robust power management systems to maximize battery life.
• Develop multi-core embedded data pipelines for real-time sensor acquisition and processing.
• Integrate biometric and environmental sensors via SPI, I2C, UART, GPIO, DMA, and interrupt-driven designs.
• Optimize firmware performance, memory usage, latency, and reliability.
• Lead board bring-up, debugging, validation, and manufacturing support.
• Collaborate closely with hardware, algorithms, product, and industrial design teams from prototype to production.
• Establish firmware best practices, testing frameworks, and CI workflows.

Requirements

• 6+ years of embedded firmware engineering experience building and delivering battery-powered wearable or consumer electronics products.
• Proven track record shipping consumer electronics from development through production.
• Deep expertise in Bluetooth Low Energy (BLE) systems and low-power embedded architectures.
• Strong proficiency in Embedded C/C++ and RTOS-based systems (e.g., FreeRTOS, Zephyr).
• Experience with ARM Cortex-M microcontrollers and modern debugging tools.
• Hands-on experience with power management architectures for low-power embedded systems.
• Experience building multi-core embedded data pipelines and optimizing always-on battery life.
• Sensor integration experience using SPI, I2C, UART, GPIO, DMA, and interrupt-driven designs.
• Board bring-up, debugging, validation, and manufacturing support experience.
• Comfortable moving quickly in a fast-paced, collaborative startup environment and working in person.
• Background in sensor fusion, signal processing, or biometric sensing.
• Experience with embedded platforms such as Nordic, Qualcomm, Ambiq, or STMicroelectronics.
• Familiarity with secure bootloaders, OTA firmware updates, wireless certification, and embedded security.
• Experience building wearable or health-tech devices.
• Visa sponsorship is not available for this role.
