Data Scientist

We are looking for a skilled and hands-on Data Scientist with 45 years of experience in developing and deploying machine learning models—ranging from traditional ML algorithms to advanced deep learning and Generative AI systems. The ideal candidate brings a strong foundation in classification, anomaly detection, and time-series modeling, along with hands-on experience in deploying and optimizing Transformer-based models. Familiarity with quantization, fine-tuning, and RAG (Retrieval-Augmented Generation) is highly desirable.

Responsibilities

• Design, train, and evaluate ML models for tasks such as classification, anomaly detection, forecasting, and natural language understanding.

• Build and fine-tune deep learning models, including RNNs, GRUs, LSTMs, and Transformer architectures (e.g., BERT, T5, GPT).

• Develop and deploy Generative AI solutions, including RAG pipelines for use cases such as document search, Q&A, and summarization.

• Perform model optimization techniques such as quantization for improving latency and reducing memory/compute overhead in production.

• Optionally fine-tune LLMs using Supervised Fine-Tuning (SFT) and Parameter-Efficient Fine-Tuning (PEFT) methods like LoRA or QLoRA.

• Define and track relevant evaluation metrics; continuously monitor model drift and retrain models as needed.

• Collaborate with cross-functional teams (data engineering, backend, DevOps) to productionize models using CI/CD pipelines.

• Write clean, reproducible code and maintain proper versioning and documentation of experiments.

Requirements

Required Skills

• 4–5 years of hands-on experience in machine learning or data science roles.

• Proficient in Python and ML/DL libraries: scikit-learn, pandas, PyTorch, TensorFlow.

• Strong knowledge of traditional ML and deep learning, especially for sequence and NLP tasks.

• Experience with Transformer models and open-source LLMs (e.g., Hugging Face Transformers).

• Familiarity with Generative AI tools and RAG frameworks (e.g., LangChain, LlamaIndex).

• Experience in model quantization (e.g., dynamic/static quantization, INT8) and deployment on constrained environments.

• Knowledge of vector stores (e.g., FAISS, Pinecone, Azure AI Search), embeddings, and retrieval techniques.

• Proficiency in evaluating models using statistical and business metrics.

• Experience with model deployment, monitoring, and performance tuning in production environments.

• Familiarity with Docker, MLflow, and CI/CD practices.

Preferred Qualifications

• Experience fine-tuning LLMs (SFT, LoRA, QLoRA) on domain-specific datasets.

• Exposure to MLOps platforms (e.g., SageMaker, Vertex AI, Kubeflow).

• Familiarity with distributed data processing (e.g., Spark) and orchestration tools (e.g., Airflow).

• Contributions to research papers, blog posts, or open-source projects in ML/NLP/GenAI.
