Job Summary

Responsibilities

• Design, develop, and maintain real-time embedded firmware in C/C++ using RTOS (FreeRTOS, ThreadX, Zephyr) for microcontrollers and processors.
• Implement device drivers (UART, SPI, I2C, I2S, ADC/DAC, USB) and integrate low-power firmware for battery-operated devices.
• Develop and integrate wireless stacks including Bluetooth (Classic & BLE), WiFi, RF subsystems, and handle OTA updates.
• Build audio processing pipelines, manage digital audio interfaces (I2S, PDM, PCM), ANC/ENC systems, and low-latency audio.
• Perform board bring-up, hardware-software integration, system debugging (JTAG, SWD, Oscilloscope), and root cause analysis.
• Optimize firmware for power consumption, memory footprint, and CPU utilization while maintaining coding standards and documentation.

Requirements

• Strong programming skills in Embedded C/C++ with ARM Cortex-M or RISC-V microcontrollers.
• Hands-on experience with RTOS-based development, hardware protocols (SPI, I2C, UART, USB), bootloaders, and OTA updates.
• Experience with Bluetooth Classic/BLE, WiFi stack integration, and RF communication subsystems.
• Background in low-power architecture, battery management, and ultra-low-power design for wearable or hearable devices.
• Proficiency with debugging tools (JTAG, SWD, Logic Analyzers) and build environments (Git, Keil, STM32CubeIDE, VS Code).
• Ability to read hardware schematics/datasheets and perform hardware-software board bring-up.
