Data Engineer / Analyst — Speech & Language Data
www.gnani.ai
Location: Bengaluru Type: Full time Function: AI Team
About the role
Every speech model we ship is downstream of a decision someone made about data. Which hours got recorded. Which transcripts were trusted. Whether the Tamil test set accidentally shares speakers with the Tamil training set. Whether a number was written as २५ or 25. Those decisions set the ceiling on what our ASR and TTS models can ever achieve — and no amount of GPU time recovers a corpus that was built carelessly.
Training accurate ASR across 22+ Indian languages takes tens of thousands of hours of audio. Training TTS voices that sound human takes carefully recorded, tightly aligned, phonetically balanced speech. Right now that data lives across many places and many heads. We want one person to own it.
This role is the data owner for Gnani’s AI team. You source it, clean it, label it, version it, catalogue it, and defend its provenance — and you are the single point of contact when any researcher needs hours, a benchmark,



or an answer about where something came from. It is a hands-on engineering and analysis role with real judgment attached: you will listen to audio, read transcripts, and be the person who notices that something is wrong before a model trains on it.
