Omni Reach - Senior Data Scientist - NLP / LLM

We are seeking a Senior Data Scientist to design, build, and deliver world-class AI / ML models that solve critical business challenges. You will work on complex data sets, apply advanced mathematical and statistical techniques, and deploy AI models that drive measurable impact. This role demands deep expertise in mathematical modelling, machine learning, and real-world problem-solving.

Key Responsibilities :

• Translate complex business objectives into mathematical formulations, predictive models, or optimization solutions.
• Conduct exploratory data analysis (EDA), feature selection, and feature engineering using advanced statistical techniques.
• Build, train, tune, and evaluate machine learning and deep learning models for various use cases : NLP, computer vision, forecasting, recommendations.
• Research, prototype, and experiment with state-of-the-art models (e.g., Transformers, LLMs, Graph Neural Networks) and adapt them to client projects.
• Perform model interpretability (SHAP, LIME, Explainable AI) and communicate model outputs to non-technical stakeholders.
• Implement statistical testing (A / B testing, hypothesis testing) to validate model impact in production settings.
• Deploy models using APIs or lightweight serving platforms and collaborate with engineering teams for MLOps.
• Stay current with academic and industry research to integrate new techniques and algorithms.
