What you will do
Own large-scale speech/audio data pipelines: build and maintain systems for data collection, cleaning, filtering, labeling, augmentation and quality control to support model training. Partner with senior speech engineers on term/hotword mining strategies based on ASR system output.
Support model training and optimization: contribute to fine-tuning and evaluating speech/language models (SpeechLLM or general LLM background both applicable), with focus on improving recognition accuracy for code-switching, names, and product terms — working alongside domain specialists on the technical algorithm design.
Domain adaptation: help fine-tune models using scenario-specific data to improve recognition of industry-specific terms across key languages and verticals.
Evaluation: build test sets and evaluation frameworks (keyword/domain-lexicon based); benchmark internal models against open-source and commercial baselines.
Skills, qualifications and experience we look for
Minimum 1 year of hands-on experience in speech, machine learning, or large-scale data engineering.
Experience in AT LEAST ONE of the following:
a) ASR/SpeechLLM model training, fine-tuning, or evaluation;
b) LLM or general ML model training/fine-tuning;
c) Large-scale audio, video, or text data pipeline work (e.g., tens of thousands of hours of audio, or TB-scale multimodal data).Solid Python and PyTorch fundamentals.
Experience with distributed data processing (e.g., Spark, Ray) — moved up from nice-to-have, since responsibility #1 requires pipeline ownership at scale.
Nice-to-Have:
Familiarity with SpeechLLM / speech SSL concepts, or exposure to models such as StepAudio or Qwen3-Omni.
Prior experience building or contributing to hotword/contextual-biasing or code-switching ASR improvements.
Publications at Interspeech, ICASSP, or other top AI venues, or speech-related patents.
Experience owning a data workstream (tens/hundreds of thousands of hours of speech) in a speech-model training project.
