  • Hands-on experience with ML frameworks (e.g., PyTorch, TensorFlow)
  • Familiarity with prototyping tools such as Streamlit or Gradio
  • Experience of engineering best practices: Git, Docker, cloud basics, and task estimation
  • Working knowledge of SQL
  • Upper-Intermediate level of English (both written and spoken)

Would be a plus:

  • Experience with other agentic or LLM orchestration tools
  • Experience with MLOps or model deployment
  • Comfortable working in Linux terminal environments

Responsibilities

  • Develop and integrate ML and NLP models to power intelligent assistant features
  • Build agentic workflows using LangChain, LangGraph, or similar frameworks
  • Prototype user interfaces and internal tools using Streamlit or Gradio
  • Collaborate with the engineering and product teams to plan and deliver ML-driven features
  • Work with Docker to manage development and runtime environments
  • Use Git for version control and write clean, maintainable code
  • Query structured data using SQL
