GreyLabs AI is building the voice operating system for India’s BFSI. Our Agentic Voice AI platform helps banks, insurers, NBFCs, and fintechs automate and humanise millions of customer conversations - across sales, collections, customer service, and compliance - in multiple Indian languages.
In under two years, we’ve scaled to 50+ enterprise clients, including RBL Bank, AU Small Finance Bank, IDFC FIRST Bank, SBI Life, ICICI Prudential Life, and Motilal Oswal - processing hundreds of millions of conversations. We raised ₹85 Crores in Series A funding led by Elevation Capital with Z47, and were recognised for “Best Use of AI in Fintech” at IFTA 2025.

The Role
This is a pure Individual Contributor role within our R&D; function. You will work across STT, LLM, and TTS systems - with a transparent mandate to close the distance between research and production. That means working directly with backend engineers and systems to ensure your work integrates into live systems cleanly, quickly, and with the observability it needs to be trusted at enterprise scale.

What You’ll Do




Lead optimisation work on STT/ASR systems - improving transcription accuracy and reducing latency for domain-specific, multilingual voice data across Indian languages and financial services contexts
Evaluate, fine-tune, and deploy LLMs for BFSI-specific tasks: information extraction, classification, summarisation, and compliance signal detection
Build and benchmark TTS capabilities against real product requirements - model quality, naturalness, latency, and integration fit with downstream systems
Design and maintain scalable prompt engineering and RAG infrastructure for production LLM features
Work closely with backend engineers and systems (hands-on) to take research outputs from working prototype to deployed, observable production feature
Establish evaluation frameworks that measure what actually matters - reproducible, deliberate, and tied to real product outcomes
Track developments in open-source LLMs and
