New Job Opening: Senior Speech Scientist in San Francisco, CA

Job Description

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.

What you'll do

• 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

What you'll bring

• 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

Nice to have

• 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.
