Responsibilities

  • Design response, feature, and self-distillation strategies to compress teacher models into deployable student models.
  • Apply post-training quantization, quantization-aware training, pruning, and architecture search to meet product size, latency, and power budgets.
  • Build a reusable distillation and compression toolchain for the audio ML team.
  • Partner with audio ML and runtime teams on training pipelines and deployment targets.
  • Define and track accuracy-retention and resource KPIs through the release cycle.
  • Profile compressed models on target hardware and iterate with DSP and runtime engineers on bottlenecks.

Requirements

  • 3+ years of professional experience in model compression, distillation, quantization, or efficient deep learning.
  • Strong fluency in PyTorch or TensorFlow and modern compression libraries.
  • Hands-on experience converting models from full precision to fixed-point or int8 with controlled accuracy loss.
  • Ability to reason about compute, memory bandwidth, and power constraints close to hardware.
  • Track record of producing models shipped to constrained devices.
  • Strong foundation in audio or sequence model architectures, including CNNs, transformers, RNN-T, or conformers.
