Position Specific Description

We are seeking a Data Scientist with strong expertise in Machine Learning (ML) and Generative AI (LLMs) to design, develop, and deploy intelligent, data-driven solutions within a modern cloud environment. 
This role involves close collaboration with data engineers and business stakeholders to build and operationalize production-grade AI systems using AWS and cutting-edge LLM frameworks. 

Core Responsibilities 

• Design, develop, and deploy machine learning and generative AI models to address complex business challenges and enhance decision-making. 
• Implement Retrieval-Augmented Generation (RAG) and semantic search pipelines that integrate large language models with enterprise data sources. 
• Apply prompt engineering, embedding techniques, and model fine-tuning using frameworks such as LangChain, LlamaIndex, and Hugging Face Transformers. 
• Collaborate with engineering teams to ensure scalable data ingestion, ETL/ELT workflows, and model deployment across cloud environments. 
• Communicate technical insights and analytical results clearly to both technical and non-technical audiences. 
• Contribute to Agile development processes and maintain code through Git/GitHub, CI/CD automation, and infrastructure-as-code (CloudFormation or equivalent). 
• Preferred Qualifications 
• 2+ years of hands-on experience with Large Language Models (LLMs) or Generative AI, such as GPT, Claude, Llama, or Mistral. 
• Proficiency in Python and key libraries including pandas, NumPy, scikit-learn, PyTorch, and TensorFlow. 
• Experience implementing RAG architectures, vector databases (e.g., Pinecone, FAISS, Weaviate), or LLM orchestration frameworks (e.g., LangChain, Semantic Kernel, CrewAI, LangGraph). 
• Practical experience working with AWS services (SageMaker, Lambda, S3, RDS, etc.). 
• Strong foundation in statistics, linear algebra, and optimization for model design and evaluation. 
• Experience creating insightful data visualizations using Tableau, Power BI, Plotly, or matplotlib. 
• Familiarity with big data technologies such as Spark, Databricks, or Snowflake. 
• Deep understanding of machine learning algorithms, data preprocessing, and model evaluation techniques. 
• Strong problem-solving abilities with a focus on reproducibility, scalability, and model governance. 
• Excellent communication skills, with the ability to translate complex analytical findings into actionable business insights. 
• Demonstrated curiosity and enthusiasm for staying current with advances in AI, Generative AI, and ML infrastructure. 
• Proven ability to work effectively in Agile and cross-functional team environments. 

Nice to Have 

• Experience with multi-agent orchestration frameworks (e.g., LangGraph, CrewAI, AutoGen). 
• 2+ years of experience in applied data science or machine learning. 
• At least 1 year of direct, hands-on experience developing or deploying LLMs or Generative AI systems. 
• Demonstrated experience with working with MLOps engineers to deploying, monitoring, and maintaining production ML models using cloud platforms. 
• Knowledge of energy market data, time-series forecasting, or optimization modeling. 
• Familiarity with reinforcement learning, probabilistic modeling, or stochastic optimization techniques.
