Job Title : Data Scientist – GenAI & Machine Learning

Experience Required : 3+ Years

Location : Nagpur

About the Role :

We are seeking a data scientist with around 3 years of experience in applied machine learning, data analytics, and GenAI solutions. The ideal candidate will have a strong foundation in traditional ML along with hands-on exposure to LLMs (Large Language Models), Retrieval-Augmented Generation (RAG) architectures, and prompt engineering. You’ll work on end-to-end data projects — from data collection and model training to deploying AI-driven applications that enhance decision-making and automation.

Key Responsibilities :

  • Analyze large datasets to generate actionable business insights.
  • Design, train, and optimize ML and GenAI models for tasks such as text generation, summarization, classification, and recommendation.
  • Develop and maintain RAG pipelines, integrating vector databases and retrieval layers to improve model accuracy and contextual awareness.
  • Implement and fine-tune LLMs using frameworks like LangChain, LlamaIndex, or Hugging Face Transformers.
  • Build data pipelines and automation workflows for scalable model deployment.
  • Collaborate with engineering teams to operationalize AI models using cloud services (AWS SageMaker, Azure ML, GCP Vertex AI).
  • Perform exploratory data analysis (EDA), feature engineering, and model evaluation using statistical and ML methods.
  • Visualize data and insights through tools like Tableau, Power BI, or Plotly Dash.
  • Document experiments, performance metrics, and maintain reproducibility of models.
  • Stay updated on the latest developments in GenAI, LLMs, and applied ML research.

Required Skills and Qualifications :

  • Bachelor’s or Master’s degree in Computer Science, Statistics, Mathematics, or a related field.
  • 3+ years of experience as a Data Scientist, ML Engineer, or AI Researcher.
  • Strong proficiency in Python (pandas, numpy, scikit-learn, matplotlib, seaborn)
  • Solid understanding of machine learning algorithms, model evaluation, and data preprocessing.
  • Experience building or fine-tuning LLMs and implementing RAG pipelines.
  • Familiarity with GenAI frameworks (LangChain, LlamaIndex, OpenAI API, Hugging Face).
  • Experience with SQL and working with large, real-world datasets.
  • Exposure to cloud platforms (AWS, Azure, or GCP) and containerization (Docker, Kubernetes).
  • Experience with version control (Git) and collaborative workflows.
  • Preferred Qualifications :

  • Knowledge of vector databases (Pinecone, FAISS, Weaviate, ChromaDB).
  • Experience with MLOps tools (MLflow, DVC, Kubeflow).
  • Understanding of prompt engineering and context optimization for LLMs.
  • Experience deploying chatbots, Q&A systems, or document intelligence solutions.
  • Strong business understanding with the ability to connect AI outcomes to business impact.
  • Soft Skills :

  • Excellent analytical and problem-solving skills.
  • Strong written and verbal communication for explaining technical concepts to non-technical teams.
  • Ability to work independently and in cross-functional teams.
  • Curiosity and passion for emerging AI technologies.
  • Create a job alert for this search
