Senior Staff Firmware Engineer

As a highly experienced Firmware Engineer with 8+ years of hands-on experience in embedded audio software development, your expertise will play a critical role in our hardware-software co-development team, impacting the performance and user experience of our AR/VR smart glasses and immersive systems. You will work on Bluetooth audio protocols, embedded DSP optimization, noise cancellation algorithms, and real-time streaming pipelines, collaborating closely with hardware, product, and design teams to drive the core embedded intelligence of our next-generation devices. **Key Responsibilities:** - Develop and optimize embedded audio firmware using C/C++, ensuring efficient performance, low power consumption, and real-time audio processing. - Work on Bluetooth audio protocols (A2DP, AVRCP, HFP), BLE profiles (HAP, TMAP, HAS, PBP), and audio codec integration (SBC, AAC, aptX, LC3). - Collaborate with hardware and systems teams to integrate microphones, speakers, amplifiers, and other peripherals via interfaces such as I2S, UART, and SPI. **Qualifications Required:** - Strong command of Embedded C/C++, including memory management, real-time programming, and hardware abstraction. - Deep understanding of Bluetooth architecture, audio profiles (A2DP, AVRCP, HFP), BLE features (HAP, TMAP, HAS), and advanced Bluetooth technologies like Angle of Arrival (AoA) and Angle of Departure (AoD). - Hands-on experience with audio codecs: SBC, AAC, aptX, and LC3. - Familiarity with noise reduction techniques such as ENC (Environmental Noise Cancellation) and ANC (Active Noise Cancellation). - Proficiency with tools and methods for debugging, testing, and performance optimization of embedded systems. In addition to firmware and embedded systems, having awareness of system-level software integration, cloud/BLE connectivity, and app-level coordination will be beneficial in delivering robust end-to-end solutions. If you have experience in working with embedded Linux or RTOS-based environments, integrating Bluetooth stacks from Nordic (nRF52), Qualcomm (CSR), or Broadcom chipsets, handling audio streaming, buffer management, latency reduction, audio quality assurance, Bluetooth sniffing and traffic analysis, audio quality testing, power optimization for wearable/portable applications, and working in Agile teams using Git, CI/CD, and writing technical documentation and test automation scripts, you would be a valuable addition to our team. Join us within the next 20 days and be part of a dynamic team driving innovation in AR/VR smart glasses and immersive systems.,
