Senior Data Scientist - Python (4-6 yrs)

Key Responsibilities :

- Research and Development : Research, design, and fine-tune machine learning models, with a focus on Large Language Models (LLMs) and Agentic AI systems.

- Model Optimization : Fine-tune and optimize pre-trained LLMs for domain-specific use cases, ensuring scalability and performance.

- Integration : Collaborate with software engineers and product teams to integrate AI models into customer-facing applications and platforms.

- Data Engineering : Perform data preprocessing, pipeline creation, feature engineering, and exploratory data analysis (EDA) to prepare datasets for training and evaluation.

- Production Deployment : Design and implement robust model deployment pipelines, including monitoring and managing model performance in production.

- Experimentation : Prototype innovative solutions leveraging cutting-edge techniques like reinforcement learning, few-shot learning, and generative AI.

- Technical Mentorship : Mentor junior team members on best practices in machine learning and software engineering.

Requirements :

- Proficiency in Python for machine learning and data science tasks.

- Expertise in ML frameworks and libraries like PyTorch, TensorFlow, Hugging Face, Scikit-learn, or similar.

- Solid understanding of Large Language Models (LLMs) such as GPT, T5, BERT, or Bloom, including fine-tuning techniques.

- Experience working on NLP tasks such as text classification, entity recognition, summarization, or question answering.

- Knowledge of deep learning architectures, such as transformers, RNNs, and CNNs.

- Strong skills in data manipulation using tools like Pandas, NumPy, and SQL.

- Familiarity with cloud services like AWS, GCP, or Azure, and experience deploying ML models using tools like Docker, Kubernetes, or serverless functions

Additional Skills (Good to Have) :

- Exposure to Agentic AI (e.g., autonomous agents, decision-making systems) and practical implementation.

- Understanding of MLOps tools (e.g., MLflow, Kubeflow) to streamline workflows and ensure production reliability.

- Experience with generative AI models (GANs, VAEs) and reinforcement learning techniques.

- Hands-on experience in prompt engineering and few-shot/fine-tuned approaches for LLMs.

- Familiarity with vector databases like Pinecone, Weaviate, or FAISS for efficient model retrieval.

- Version control (Git) and familiarity with collaborative development practices
