Senior Speech Scientist

Want to build speech AI that actually sounds human?

You’ll be joining a well‑funded speech AI startup with strong customer traction. They’re building ultra‑realistic voice technology that handles natural laughter, breathing, seamless language switching, and accurate pronunciation across languages and accents.

As their Senior Research Scientist, you’ll work hands‑on to expand their foundation models and push the boundaries of what’s possible in speech AI: exploring multilingual capabilities, long‑context generation, full‑duplex modeling for natural conversations with interruptions, and novel architectures that balance speed with control.

• Conduct research to advance their core speech models and extend product capabilities
• Develop and experiment with new model architectures and training approaches
• Work on large‑scale model training and data systems
• Collaborate with the team to take research from concept to deployed systems

• 3+ years of experience in speech synthesis, audio generation, or generative modeling
• Experience with audio generation using LLMs
• Solid background in modern language model architectures
• Proven ability to ship research into production systems
• Experience training large‑scale models

• Published research in speech or generative modeling
• Experience with real‑time speech systems or multimodal models

Ideally in SF, but can also consider remote worldwide. Comp is up to $250K base DOE, plus equity.
