Battery & Power Management Specialist at TraceWay
The Battery and Power Management Specialist at TraceWay oversees the critical intersection of lithium cell hardware and the Zephyr RTOS kernel to ensure the Trace smartwatch achieves its goal of weeks of runtime. This role requires an expert capable of fine-tuning the operating system’s tickless idle operation and deterministic scheduling to minimize sleep currents while keeping radio and sensor tasks predictable. The specialist performs deep power profiling using the device’s dedicated headers and serial wire debug ports to isolate energy consumption at every layer of the hardware. Beyond standard hardware validation, this engineer develops open firmware for battery management and state of charge estimation that remains fully visible and modifiable by the owner. They are responsible for maintaining device tree source files and CMake build scripts to allow users to reconfigure power rails and pin assignments without proprietary tools. This position demands a mastery of embedded C, low power wireless protocols, and the ability to design resilient power systems for a platform that encourages user modification and external sensor integration. TraceWay seeks a professional who prioritizes transparency and open hardware principles over the typical sealed and cloud tied consumer electronics model. Candidates should be comfortable working with standard GNU tools and the Zephyr SDK to deliver a high performance wearable platform for the global developer community.
