Senior Software Developer

Role Overview: As a Senior Firmware Engineer (SSD-1) with 7-10 years of experience, you will be responsible for designing, developing, and optimizing embedded firmware solutions for next-generation connected and audio/XR devices. Your expertise in Bluetooth/audio SoCs such as Jeili, Bluetrum, or Wuqi, along with deep knowledge of low-level driver development, RTOS systems, and hardware-software integration will be crucial for this role. You will own firmware architecture, hardware bring-up, performance optimization, and collaborate cross-functionally with hardware, QA, and product engineering teams. Key Responsibilities: - Firmware Development & Architecture - Design, develop, and maintain embedded firmware for Bluetooth/audio-based devices. - Architect modular and scalable firmware components aligned with product requirements. - Implement real-time functionalities using RTOS or bare-metal systems. - Low-Level Driver & Peripheral Integration - Develop and optimize drivers for peripherals (SPI, I2C, UART, ADC, PWM, GPIO). - Integrate audio codecs, Bluetooth stacks, and connectivity modules. - Perform hardware bring-up and board support package (BSP) customization. - Performance Optimization & Debugging - Optimize power consumption, memory footprint, and CPU utilization. - Debug complex hardware-software issues using JTAG, oscilloscopes, and logic analyzers. - Resolve latency, synchronization, and signal integrity challenges. - System Stability & Compliance - Ensure firmware reliability, robustness, and fail-safe mechanisms. - Support product validation, EMI/EMC compliance, and certification processes (Bluetooth SIG, etc.). - Implement OTA firmware update mechanisms and secure boot processes. - Cross-Functional Collaboration & Leadership - Collaborate with hardware, QA, and manufacturing teams for smooth product release cycles. - Mentor junior engineers and conduct firmware code reviews. - Contribute to technical documentation, architecture reviews, and roadmap planning. Qualification Required: - 710 years of experience in embedded firmware development. - Strong proficiency in Embedded C/C++. - Hands-on experience with Bluetooth/audio SoCs (Jeili, Bluetrum, Wuqi preferred). - Experience working with RTOS (FreeRTOS or similar) or embedded Linux. - Strong understanding of microcontrollers, memory management, and interrupt handling. - Experience with debugging tools (JTAG, oscilloscopes, logic analyzers). - Familiarity with version control systems (Git) and structured development lifecycle.
