Job description

Machine Learning Engineer (Audio Training)

We’re building human-like, real-time voice models focused on natural turn-taking, interruption handling, and low-latency speech.

What you’ll do

  • Design and generate conversational audio training data
  • Train and fine-tune audio / speech models
  • Build evaluation for latency, overlap, and interruption
  • Own the loop: data → training → eval → production

What we’re looking for

  • Strong ML background (PyTorch)
  • Experience with audio or speech models
  • Solid intuition for timing, latency, and real-time systems
  • Startup / ownership mindset

Nice to have

  • TTS, ASR, speech-to-speech, or streaming inference experience

Competitive comp + meaningful equity. Founding-level ownership.
