Overview

We are seeking a highly skilled Data Scientist with strong Python development experience and a deep background in fine‑tuning Large Language Models (LLMs) using custom datasets. The ideal candidate has extensive hands‑on expertise with modern transformer‑based architectures, natural language processing techniques, and machine learning frameworks. Experience working in the banking domain and the ability to build, optimize, deploy, and evaluate NLP solutions are highly preferred.

Key Responsibilities

• Fine‑tune Large Language Models (LLMs) such as LLAMA2, GPT‑4, GPT‑3, Gemini Pro using domain‑specific datasets.
• Develop scalable NLP and ML pipelines using Python, PyTorch, HuggingFace Transformers , and relevant libraries.
• Design and implement advanced prompting strategies for GPT‑based and open‑source LLMs.
• Train, evaluate, and optimize transformer-based models (e.g., BERT, RoBERTa).
• Build machine learning models such as SVM, Logistic Regression, Random Forest, Naïve Bayes, Neural Networks , etc.
• Apply modern NLP techniques including:
• Word embeddings (Word2Vec, GloVe, FastText, USE)
• Contextual embeddings (BERT, ELMo, Transformer encodings)
