Senior Data Scientist (Gen AI)

About the Role:

We are looking for an AI Engineer with experience in Speech-to-text and Text Generation to solve a Conversational AI challenge for our client based in EMEA. The focus of this project is to transcribe conversations and leverage generative AI-powered text analytics to drive better engagement strategies and decision-making.

The ideal candidate will have deep expertise in Speech-to-Text (STT), Natural Language Processing (NLP), Large Language Models (LLMs), and Conversational AI systems. This role involves working on real-time transcription, intent analysis, sentiment analysis, summarization, and decision-support tools.

Key Responsibilities

1. Conversational AI & Call Transcription Development

• Develop and fine-tune automatic speech recognition (ASR) models
• Implement language model fine-tuning for industry-specific language.
• Develop speaker diarization techniques to distinguish speakers in multi-speaker conversations.

2. NLP & Generative AI Applications

• Build summarization models to extract key insights from conversations.
• Implement Named Entity Recognition (NER) to identify key topics.
• Apply LLMs for conversation analytics and context-aware recommendations.
• Design custom RAG (Retrieval-Augmented Generation) pipelines to enrich call summaries with external knowledge.

3. Sentiment Analysis & Decision Support

• Develop sentiment and intent classification models.
• Create predictive models that suggest next-best actions based on call content, engagement levels, and historical data.

4. AI Deployment & Scalability

• Deploy AI models using tools like AWS, GCP, Azure AI, ensuring scalability and real-time processing.
• Optimize inference pipelines using ONNX, TensorRT, or Triton for cost-effective model serving.
• Implement MLOps workflows to continuously improve model performance with new call data.
