• Perform data preprocessing, feature engineering, and model evaluation
• Integrate ML outputs into chatbot or workflow interfaces
• Support data pipeline development and automation
• Collaborate with internal team and occasionally clients to understand requirements
• Document model logic, workflows, and implementation details

Required Qualifications

• Bachelor’s or Master’s degree in Computer Science, Data Science, Statistics, Engineering, or related quantitative field

• Experience building APIs or backend services (FastAPI, Flask, or similar)
• Strong analytical and problem-solving skills
• Ability to work independently and communicate clearly

Preferred Qualifications

• Graduate degree or currently pursuing MS in AI, Data Science, or related field
• Experience with agent frameworks (LangChain, LlamaIndex, LangGraph, CrewAI, etc.)
• Experience deploying or integrating ML models into applications
• Knowledge of vector databases or embeddings
• Familiarity with AWS, GCP, or Azure
• Prior internship or project experience building AI/ML applications
