About the role

  • 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

  • Design, implement, and manage audio use cases on SoC platforms across playback, capture, voice, and always-on listening paths
  • 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
  • Hark is an artificial intelligence company building advanced, personalized intelligence.
  • We're pairing that intelligence with next-generation hardware to create a universal interface between humans and machines.
  • Tune audio quality and validate behavior across acoustic conditions

Requirements

  • 3+ years of professional firmware or embedded audio development, ideally on consumer products that have shipped at scale
  • 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

Nice to have

  • 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.
  • Background shipping voice-first or far-field audio products
  • The pay offered for this position may vary based on several individual factors, including job-related knowledge, skills, and experience.
  • This information will be shared if an employment offer is extended.
