JOB TITLE:

DSP Software Engineer (Job Code: MK0711)

JOB DETAILS :
Responsible for the real-time audio, DSP, and rendering software across Sonos products through expertise in signal processing, embedded systems, and software architecture and strong proficiency in Rust, C++, and Python. Define requirements, write design documents, ensure acceptance criteria, and maintain roadmaps in coordination with cross-functional partners. On the implementation side, design and build modular real-time audio and DSP components in Rust and C++, making calls on architecture, performance, and portability across processors and operating environments.

This includes integrating and optimizing machine learning models for audio workloads covering classification, enhancement and spatial processing on embedded platforms, as well as bringing in new multi-channel audio formats, codecs/decoders, and DSP algorithms. Design hard real-time software pipelines with patterns and interfaces that work across the product family, and work with Sonos-native mechanisms for system parameter control. Debug audio routing, timing, and synchronization problems across wireless networks, cross-domain issues touching DSP algorithms, embedded RTOS/Linux systems, wireless audio transport, and hardware.

Own the testing and validation practice by building DSP simulation environments and software test frameworks in Python across diverse architectures, define testing strategy using GTest and Rust frameworks, and improve CI practices. Collaborate closely with acoustics, networking, hardware, application software, and audio system engineers. Set engineering standards and mentor engineers on the team and in partner groups.

EDUCATION AND EXPERIENCE REQUIREMENTS:

Master’s degree (or foreign equivalent) in Electrical Engineering, Computer Engineering, Computer Science, or Acoustic Engineering plus 2 years of experience in the offered position or related position. SPECIAL REQUIREMENTS:
Must possess expertise/knowledge sufficient to adequately perform the duties of the job being offered. Expertise/knowledge may be gained through employment experience or education. Such expertise/knowledge cannot be "quantified" by "time". Required expertise/knowledge includes:
Understanding of digital signal processing concepts, including filtering, sampling, latency, and numeric representation.

Experience with Rust, C++, and Python for implementing DSP algorithms, automating audio tests, and validating software. Experience designing and validating real-time DSP audio systems for consumer electronics.

Experience with real-time systems, embedded Linux, and RTOS environments. Experience evaluating and optimizing embedded DSP algorithms using MATLAB and Simulink. Experience integrating and optimizing machine learning models for audio on embedded systems, including classification, enhancement, spatial processing, and ML/DSP hybrid techniques. Knowledge of industry audio formats, codecs/decoders, and metadata, including Dolby Atmos, AAC, FLAC, Opus, OGG, MP3, and WAV. Experience creating DSP visualization or modeling tools in C++ for real-time audio development.
