DSP Software Engineer

We build highdefinition multichannel audio experiences that set industry standards. Our products stream all the music on earth throughout the home wirelesslyand your work will help ensure the system remains simple elegant and robust.

Location: Boston MA or Seattle WA

Role Overview

Our mission is to advance the Sonos audio pipeline through bold innovation in DSP machine learning and embedded systems creating seamless sound experiences that power Sonos role as the essential platform for home entertainment. Working in close partnership with the Sound Experience Trueplay and Headphone DSP teams we design and deliver algorithms across audio voice and sensor domainsspanning both traditional DSP and cuttingedge machine learning.

As an DSP Software Engineer on the Player DSP team youll contribute to the audio processing DSP and rendering software that powers every Sonos product. You will work across lowlevel embedded systems realtime signal processing and audio platform architecture to deliver highperformance audio experiences.

This role is ideal for an earlycareer engineer (IC1/IC2) who is passionate about audio DSP embedded systems and developing reliable wellstructured software. You should be comfortable working in Rust and C eager to learn and excited to develop features that directly impact how millions of listeners experience sound.

What Youll Do

• Implement extend and maintain modular realtime audio and DSP components in Rust and C.

• Contribute to integrating and optimizing machine learning models for audio including classification enhancement or spatial processing workloads on embedded platforms.

• Collaborate on the design of hard realtime software architectures for audio pipelines.

• Help integrate new multichannel audio formats codecs and DSP algorithms into Sonos platforms.

• Work with senior engineers to solve audio routing timing and synchronization challenges across wireless networks.

• Develop unit tests using GTest or Rust testing frameworks and contribute to continuous integration.

• Debug complex issues that may span DSP algorithms embedded RTOS/Linux systems wireless audio transport or hardware interactions.

• Implement and document clean maintainable portable software that can run across processors and operating environments.

What Youll Need

• Exposure to or interest in machine learning for audio (e.g. model inference on embedded systems audio feature extraction basic ML/DSP hybrid techniques).

• 03 years of experience in embedded software DSP or systems programming (industry academic or projectbased experience).

• Proficiency in Rust and C programming.

• Foundational understanding of digital signal processing concepts (filtering sampling latency numeric representation etc.).

• Exposure to realtime systems embedded Linux or RTOS environments.

• Familiarity with multichannel audio concepts streaming formats or codecs (e.g. AAC FLAC Opus Atmos) is a plus.

• Ability to write unit tests and design for testability.

• Strong problemsolving skills and willingness to work handson at all layers of the audio stack.

• Interest in audio technology DSP music or consumer hardware.

Nice to Have

• Experience implementing or deploying machine learning models for audio (e.g. noise suppression beamforming sound classification spatial audio ML techniques).

• Experience with performance benchmarking on embedded hardware.

• Coursework or project experience in wireless networking timing or synchronization.

• Exposure to source control and issue-tracking systems (e.g. Git Jira Perforce).

• Experience with performance benchmarking on embedded hardware.

• Coursework or project experience in wireless networking timing or synchronization.

• Exposure to source control and issuetracking systems (e.g. Git Jira Perforce).

Why Youll Love This Role

Youll work closely with engineers across DSP acoustics hardware system software and application layersgaining deep experience in both embedded systems and audio technology. Youll help shape features that define the listening experience for millions of customers and contribute to a collaborative engineering culture built around growth curiosity and innovation.
