About the job
Build and ship production speech models for voice conversion and related tasks, spanning research, data, evaluation, training, and inference.
What you'll do
- Develop and train large-scale speech models, including pre-training, fine-tuning, and alignment.
- Define data strategies and design objective and subjective evaluations, including listening tests and safety checks.
- Deliver reliable production pipelines by optimizing latency, memory, and cost and supporting monitoring and rollback.
What they ask for
- Exceptional experience with large-scale audio models (>8B parameters, >500k hours of data).
- Hands-on experience with diffusion and/or flow-matching transformers and training audio VAEs, neural audio codecs, and vocoders.
- Experience with multi-node, multi-GPU distributed training and strong PyTorch and software engineering skills.
- Have shipped large-scale speech/audio or multimodal generative models to production.
Nice to have
- Experience with voice cloning, speech control/steerability, or expressive speech generation.
- Notable publications and/or open-source contributions in speech/audio/ML.
Tools
PyTorch, FSDP, DeepSpeed, CUDA, Triton, C++, GRPO, DPO
AI focus
Research, train, evaluate, and deploy safe, steerable speech models for voice conversion and related tasks such as controllable TTS and voice design.
