Senior ML Research Scientist, Speech

About the role

The Speech Research team takes this further: better accuracy on Indian languages and code-mixed speech, natural expressive TTS, and full-duplex speech-to-speech models that cut latency across the whole conversation. your model ships to live enterprise calls, not a leaderboard 8 kHz telephony audio, Hinglish and code-switching, accents, noisy environments, domain entities (loan numbers, policy IDs, names)

What you'll do

• Lead one research track and set its roadmap with the CTO and product leads, tied to customer metrics (accuracy, naturalness, latency, cost per minute)
• Design novel architectures and pre-train speech foundation models from scratch on large multilingual corpora (100k+ hours), including self-supervised pre-training
• Fine-tuning and continued training are tools, not the whole job
• Build the data strategy: sourcing, licensing, synthetic data generation, labelling quality and consent-compliant use of production audio
• Define evaluation standards and benchmarks that predict real call outcomes, and run honest comparisons against external vendors

What you need

• 3–6 yrs of experience
• Machine learning
• Research
• LLMs
• PhD
