Job Description: DSP Audio Firmware Engineer (SHARC Preferred)

We are seeking a highly skilled DSP Audio Firmware Engineer with experience in developing, optimizing, and implementing digital signal processing (DSP) algorithms for audio applications. The ideal candidate will have hands-on experience working with SHARC (Super Harvard Architecture Single-Chip Computer) processors and a solid understanding of embedded firmware development for audio systems.


Key Responsibilities:

  • Firmware Development: Design, develop, and optimize embedded firmware for audio DSP systems, with a focus on SHARC processors.
  • Audio Signal Processing: Implement and fine-tune audio DSP algorithms (e.g., filtering, equalization, compression, and dynamic range control) for professional audio equipment, consumer electronics, or other audio-related applications.
  • Performance Optimization: Optimize DSP algorithms for real-time performance, ensuring minimal latency and efficient resource utilization.
  • Algorithm Implementation: Translate high-level DSP algorithms into efficient, real-time firmware code for SHARC processors.
  • Debugging & Troubleshooting: Conduct comprehensive debugging and troubleshooting of audio signal processing algorithms to ensure the quality and reliability of the system.
  • Collaboration: Work closely with cross-functional teams, including hardware engineers, software developers, and acoustics engineers, to integrate DSP firmware with other components of the system.
  • Documentation: Create and maintain detailed documentation for the developed firmware, including specifications, architecture, and user manuals.
  • Testing & Validation: Perform testing, simulation, and validation of audio DSP systems to meet performance and quality standards.


Requirements:

  • Experience with DSP Processors: Proficiency in working with SHARC processors (Analog Devices) is highly preferred.
  • Programming Skills: Strong proficiency in C/C++ for embedded firmware development.
  • DSP Knowledge: Solid understanding of digital signal processing techniques, especially in the context of audio (filtering, EQ, reverb, noise suppression, etc.).
  • Firmware Development: Proven experience in developing and optimizing firmware for audio systems, with hands-on experience in real-time processing and multi-threading.
  • Embedded Systems: Experience in embedded systems development, including low-level firmware programming, hardware interfacing, and real-time operating systems (RTOS).
  • Tools & Debugging: Familiarity with debugging tools, simulators, and development environments for SHARC processors and DSP.
  • Communication Protocols: Knowledge of communication protocols such as I2C, SPI, UART, etc.
  • Audio Standards: Familiarity with audio industry standards and formats (e.g., PCM, Dolby, DTS, etc.).


Preferred Qualifications:

  • Experience with MATLAB/Simulink or similar tools for DSP algorithm development and simulation.
  • Familiarity with Assembler language for performance-critical portions of code.
  • Experience with audio system design or working on audio products like amplifiers, soundbars, or headphones.
  • Knowledge of audio codecs and streaming protocols.


Education:

  • Bachelor’s degree in Electrical Engineering, Computer Science, or a related field. Master's degree is a plus.
