About the role
Senior Software Developer SSD-1 (Firmware) Experience: 7 10 Years Location: Mumbai / Navi Mumbai Employment Type: Full-Time Job Summary We are seeking an experienced Senior Firmware Engineer (SSD-1) to design, develop, and optimize embedded firmware solutions for next-generation connected and audio/XR devices. The ideal candidate will have strong 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. This role requires ownership of firmware architecture, hardware bring-up, performance optimization, and cross-functional collaboration with hardware, QA, and product engineering teams. Key Responsibilities 1. 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. 2. 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. 3. 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. 4. 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. 5. 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. Required Skills & Qualifications 7 10 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. Preferred Skills Experience with BLE stack customization and audio streaming protocols. Knowledge of DSP/audio signal processing basics. Familiarity with secure firmware development (encryption, secure boot). Exposure to IoT, wearable, or XR devices. What Success Looks Like Secure firmware releases with minimal post-production defects. Optimized power and performance benchmarks. On-time hardware bring-up and product certification. Improved code quality and reusable firmware modules across product lines Disclaimer: This job posting has been aggregated from external source.
