About the Job

Requirements

At least 5 years of experience developing production-grade embedded C for microcontrollers.
Direct experience with embedded real-time operating system environments such as Zephyr, FreeRTOS, or similar, and bare-metal firmware bring-up.
Demonstrated skill developing I2C and SPI peripheral drivers, with hands-on debugging using logic or protocol analyzers.
Experience integrating and debugging Linux kernel drivers, especially within the power supply subsystem.
Proficiency in reading datasheets and implementing register-level and bitfield logic, including management of errata.
Ability to debug on real hardware using JTAG/SWD, serial consoles, and bench instrumentation such as power analyzers, SMUs, and thermal chambers.
Python proficiency for test automation, device log parsing, and field data analysis.
A bachelor's degree in Electrical Engineering, Computer Engineering, or Computer Science, or equivalent practical experience.

Responsibilities

Design, develop, and maintain battery and power-management firmware for resource-constrained microcontrollers, including fuel-gauge drivers, charge control, and thermal mitigation.
Integrate and validate fuel gauges and charger ICs at the register level by configuring NVM, setting protection thresholds, implementing JEITA profiles, and supporting capacity-learning features.
Develop the device-side telemetry stack for battery data, ensuring signals are validated end-to-end against hardware ground truth and actionable for field diagnostics.
Diagnose and root-cause complex field and laboratory failures that cross hardware/software boundaries, distinguishing root triggers in firmware, silicon, or power-management peripherals.
Collaborate with electrical engineering, cell suppliers, hardware validation, and product teams, translating between component specifications and observed fleet behaviors.
Drive firmware correctness and reliability, particularly in safety-critical decisions such as charge termination and power-off thresholds.

Desired Qualifications

Hands-on experience with battery-management technologies, including fuel gauges, coulomb counting, OCV/impedance-based state-of-charge estimation, charger ICs, JEITA charging, battery NVM configuration, and protection circuits.
In-depth knowledge of lithium-ion cell behavior, including aging, temperature effects, and failure mechanisms, to inform conversations with suppliers and engineering peers.
Experience analyzing data at fleet scale with SQL or equivalent analytics tools, with a focus on validating fixes against real-world field data.
Ownership of hardware components across consumer product lifecycles, including EVT, DVT, PVT, and factory bring-up, with active involvement in failure-analysis loops.
Track record of responding to production incidents for shipped hardware in the field.
