Senior Firmware Engineer

What You’ll Do
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.

What We’re Looking For
Required

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.

Nice to Have

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.
