About the Role We're looking for an experienced Audio Firmware Engineer to develop and optimize next-generation embedded audio solutions on Android and SoC platforms. This role spans audio system bring-up, DSP pipeline integration, firmware optimization, and deployment of advanced audio/AI features for consumer devices. You will work across the software stack-from Android audio framework and HAL layers down to DSP-bringing production-quality audio experiences to market. This is hands-on work close to silicon, with direct impact on how every user experiences the product.
Responsibilities- Bring up audio on new hardware in the Android system - codecs, mics, speakers, routing, and low-level platform integration
- Design, implement, and manage audio use cases on SoC platforms across playback, capture, voice, and always-on listening paths
- Integrate and tune audio paths across the Android audio stack (HAL, AudioFlinger, Audio Policy Manager, TinyALSA/ALSA) and the underlying SoC audio frameworks
- Debug complex audio issues end-to-end using platform logs, working from kernel and DSP traces up through application-level symptoms
- Partner with the AI team to support audio-driven inference workloads (wake word, ASR, speech enhancement) within latency, power, and memory budgets
- Collaborate with hardware, acoustics, and product teams from prototype through production to ship audio that feels effortless to users
Requirements- 3+ years of professional firmware or embedded audio development, ideally on consumer products that have shipped at scale
- Proficient with C/C++ in resource-constrained, real-time environments
- Familiar with Android audio architecture: Audio HAL, AudioFlinger, Audio Policy Manager, and TinyALSA/ALSA interfaces
- Hands-on experience with audio tooling and frameworks
- Comfort working across the full audio stack - kernel drivers, DSP firmware, HAL, framework - and debugging issues that span all of it
- Experience working alongside hardware engineers during board bring-up and reading schematics for audio subsystems
Bonus Qualifications- Working knowledge of audio processing algorithms - dynamic range control, echo cancellation, noise suppression, beamforming, and similar
- DSP optimization experience, including fixed-point development, SIMD and VLIW.
- Tune audio quality and validate behavior across acoustic conditions
- Experience deploying machine learning models on embedded platforms, especially audio models running on DSP or NPU
- Background shipping voice-first or far-field audio products
CompensationThe US base salary range for this full-time position is between $120,000 - $300,000 annually.
The pay offered for this position may vary based on several individual factors, including job-related knowledge, skills, and experience. The total compensation package may also include additional components/benefits depending on the specific role. This information will be shared if an employment offer is extended.
