Machine Learning Engineer, TTS

About the Role:

We’re looking for a Research / ML Engineer to join our Speech Team to build state-of-the-art speech systems end-to-end—from data specs through production inference. You’ll drive the model ↔ data ↔ eval flywheel for TTS and adjacent tasks (voice cloning, controllable TTS, voice conversion and more), partnering closely with research, data, and infra to ship fast, reliable, and cost-aware models. In this role, you will work at the intersection of cutting-edge research and practical engineering, contributing to the development of safe, steerable, and trustworthy AI systems.

What You’ll Do:

• Model Building: Architect, implement, pre-train, fine-tune, and post-train/alignment (e.g., GRPO/DPO) for large-scale speech models.

• Project Leadership: Independently lead small research projects while collaborating on larger team initiatives.

• Experimental Design: Design, run, and analyze scientific experiments to advance our understanding of the models.

• Tool Development: Develop and improve dev tooling to enhance team productivity.
