Voice AI Data & Design

About the Role

OpenAI is expanding realtime, multimodal interaction across ChatGPT and developer APIs, including voice experiences. We're seeking a handson, productminded engineer who can transform breakthrough speech, audio, and generative models into polished, scalable user experiences. If you're passionate about building expressive, reliable, and safe AI voices that people love, this role is for you.

What you'll do

• Develop & optimize speech and audio ML models (TTS, voice conversion, expressive prosody, lowlatency streaming) for production.

• Design scalable data pipelines for voice collection, labeling, quality metrics, and human preference testing.

• Create and operationalize voice persona frameworks that connect linguistic, acoustic, and stylistic features to model training.

• Prototype generative audio capabilities (music, FX, ambient) that enhance conversational and accessibility experiences.

• Integrate voice models into ChatGPT voice, developer APIs, and accessibility features in collaboration with product, design, safety, and platform teams.

• Instrument telemetry & performance monitoring to drive continuous quality, robustness, and bias/fairness improvements across languages and dialects.

• Establish responsible data practices (consent, licensing, voice likeness safeguards) in partnership with Legal, Policy, and Safety.

What we're looking for

• Proven experience building and shipping production voice or speech ML systems (TTS, voice cloning, or generative audio).

• Deep understanding of speech synthesis pipelines: text normalization, linguistic/phonetic features, acoustics, vocoding, and prosody modeling.

• Strong ML engineering expertise in Python and a major deep learning framework (PyTorch strongly preferred).

• Familiarity with audio tooling, data augmentation for speech, and metrics (MOS, intelligibility, latency, naturalness, persona fidelity).

• Collaborative, cross-functional approach with clear, user-oriented communication.

Nice to have:

• Experience with voice casting workflows or script/prompt design for large-scale data programs.

• Background in creative audio generation (music, sound design) and multimodal ML.

• Track record of 01 product incubation or team leadership.

• Patents, publications, or open-source contributions in speech, audio, or generative modeling.

• Multilingual voice development.
