## About the Role

Robotics, ARM (Advanced RISC Machine), System-on-a-Chip (SoC), Kernel Programming, Digital Signal Processing (DSP), Product Data Management (PDM), Audio Hardware, TDM (Time Division Multiplexing), Power Amplifier, Use Cases, * 8-10 years in embedded audio software engineering.

 * Strong C, with C++ where the framework demands it, on embedded Linux and/or Android.
 * Deep ALSA / ASoC driver development experience - DAPM, DAI links, kcontrols, codec drivers.
 * Hands-on with digital audio interfaces: I2S, TDM, SoundWire, PDM; clocking and sample-rate handling.
 * Audio DSP integration - firmware load, control protocol, offload playback/capture paths.
 * Understanding of audio signal processing fundamentals and voice front-end algorithms (AEC, NS, beamforming).
 * Latency, power and audio quality measurement and debugging methodology.

Other Requirements

 * Android audio HAL, AAudio or audio policy manager experience.
 * PipeWire or PulseAudio module development.
 * Programming on on-SoC audio/compute DSP cores using vendor DSP toolchains.
 * Bluetooth audio profiles (A2DP, HFP, LE Audio / LC3).
 * Acoustic tuning and lab measurement experience.

## Description

Own the audio subsystem on ARM-based SoC platforms - kernel audio drivers, userspace audio frameworks, DSP offload and voice/audio processing pipelines for edge, enterprise and robotics devices., * Bring up audio hardware paths - codecs, amplifiers, I2S/TDM/SoundWire/PDM interfaces and clocking.

 * Develop and maintain ALSA SoC (ASoC) machine, platform and codec drivers, DAPM routing and mixer controls.
 * Integrate userspace audio frameworks (PulseAudio/PipeWire, TinyALSA, or Android audio HAL) and define routing and use-case policy.
 * Enable audio DSP offload - firmware loading, control interfaces, tunnelled playback and low-power always-on listening paths.
 * Integrate and tune voice and audio processing chains: echo cancellation, noise suppression, beamforming, multi-mic arrays and keyword detection.
 * Measure and optimize end-to-end audio latency, glitch rate, power consumption and objective audio quality.
 * Debug pops, clicks, underruns, XRUNs, sync drift and DSP crashes using traces, logs and audio capture analysis.
 * Support acoustic tuning cycles and define audio validation and regression coverage.
