This is a senior embedded firmware role on the core hardware team of an early-stage wearable AI startup, where you'll architect and ship the firmware powering a next-generation biometric wearable device. You'll work hands-on from prototype through mass production, playing a foundational role in defining how the platform is built and how it performs in the real world. The work sits at the intersection of low-power embedded design, sensor integration, and production engineering — shipping a category-defining consumer product that matters to users.
Architect and develop embedded firmware for battery-powered wearable devices.
Own core systems for low-power wireless connectivity, sensor processing, and real-time 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 interrupts.
Optimize firmware performance, memory usage, latency, and reliability.
Lead board bring-up, debugging, validation, and manufacturing support.
Collaborate with hardware, algorithms, product, and industrial design teams across the full product lifecycle.
Establish firmware best practices, testing, and CI workflows for the team.
6+ years of embedded firmware engineering experience, with a track record of shipping battery-powered wearable or consumer electronics devices to 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).
Hands-on experience with ARM Cortex-M microcontrollers and modern debugging tools.
Experience with multi-core embedded data pipelines and always-on power optimization.
Sensor integration experience using SPI, I2C, UART, GPIO, DMA, and interrupt-driven designs.
Familiarity with secure bootloaders, OTA firmware updates, wireless certification, and production firmware.
Background in sensor fusion, signal processing, or biometric sensing is a strong plus.
Experience with platforms such as Nordic, Qualcomm, Ambiq, or STMicroelectronics is a plus.
Comfortable working in person with a small, fast-moving engineering team.
This role is on-site in New York, NY. Visa sponsorship is not available.
