Audio Engineer - Embedded Systems

Role is Open for both Burlingame, CA and Redmond, WA - Onsite

Client is seeking a talented Audio Embedded Firmware Engineer to join our team focused on advancing audio technologies for next-generation products. In this role, you will integrate, validate and optimize embedded firmware for next-generation audio products. You will collaborate closely with cross-functional teams including architecture, hardware, software, and product design to deliver high-quality audio systems and experiences.

• Develop, validate, and optimize embedded firmware for audio subsystems on custom hardware platforms.
• Integrate and debug audio features and algorithms on embedded systems (e.g., ARM Cortex‑M, DSP cores).
• Collaborate with hardware, software, and QA teams to define requirements, validate designs, and ensure robust system integration.
• Conduct board bring‑up, hardware validation, and troubleshooting using oscilloscopes, logic analyzers, and other lab equipment.
• Write and maintain clear, well‑documented code, validation procedures and technical documentation.
• Participate in code reviews and contribute to continuous improvement of firmware development processes.
• Support manufacturing and test engineering teams with firmware‑related issues.

• Proficiency in C/C++ for embedded systems.
• Experience with RTOS or bare‑metal firmware development.
• Experience with distributed compute (Multi‑core, multithread) development.
• Familiarity with audio signal processing concepts and hardware interfaces (I2S, PDM, I2C, SPI, UART).
• Strong debugging and problem‑solving skills using lab equipment and software tools.
• Excellent communication and teamwork skills.

• Experience with audio DSPs, ideally HiFi and Qualcomm Hexagon.
• Experience with power management and low‑power firmware design.
• Knowledge of Audio Precision equipment and tools.
• Familiarity with Bluetooth audio stacks, USB audio, or wireless audio protocols.
• Knowledge of hardware design and schematic/PCB review.
• Experience working in an Agile development environment.

4+ years of experience in C/C++ embedded systems development, RTOS/bare‑metal firmware, audio DSP integration (HiFi/Hexagon), hardware bring‑up and debugging, and multi‑core/multithread distributed compute.

Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, Computer Science, or related field.
