    • LangGraph
    • Semantic Kernel
    • AutoGen
    • CrewAI
    • OpenAI Agents SDK
  • Demonstrate working knowledge of multiple agent frameworks and their trade-offs
  • Apply prompt engineering, few-shot learning, and retrieval techniques to improve LLM performance
  • Build reusable components for agent orchestration, tool usage, and workflow design
  • Design and implement semantic search and vector-based retrieval systems
  • Hands-on experience with:
    • Azure AI Search
    • PostgreSQL (pgvector)
  • Optimize embedding strategies, indexing, and query performance
  • Implement LLM evaluation approaches (offline testing, basic automated evaluation pipelines)
  • Define and track quality metrics such as accuracy, relevance, and response quality
  • Apply techniques for hallucination detection and mitigation
  • Build basic monitoring and observability for AI systems (logs, traces, performance metrics)
  • Continuously improve model performance based on evaluation insights
  • Develop APIs and microservices for integrating AI systems
  • Work with cloud platforms (Azure/AWS/GCP) and containerization (Docker)
  • Contribute to deployment pipelines and production readiness
  • Prototype and validate solutions through POCs and pilots

Requirements

  • 6–9 years of experience in AI/ML
  • Strong Python skills and experience with ML frameworks (PyTorch or TensorFlow)
  • Practical experience building LLM-based applications and RAG pipelines
  • Hands-on experience with at least one agentic AI framework:
    • LangGraph, Semantic Kernel, AutoGen, CrewAI, or OpenAI Agents SDK
  • Familiarity with multi-agent workflows and orchestration patterns
  • Experience with vector databases and semantic search systems
  • Hands-on exposure to:
    • Azure AI Search
    • pgvector (PostgreSQL)
  • Understanding of embeddings and similarity search
  • Experience or strong understanding of:
    • LLM evaluation techniques
    • Output quality measurement
    • Hallucination detection approaches
    • Monitoring and observability concepts
  • Agentic AI: LangGraph, Semantic Kernel, AutoGen, CrewAI, OpenAI Agents SDK
  • RAG Frameworks: LangChain, LlamaIndex
  • Vector Databases: Azure AI Search, pgvector
  • LLM/ML: PyTorch, OpenAI APIs
  • Serving: FastAPI
  • Infra: Azure/AWS/GCP, Docker
  • Monitoring: LangSmith (or similar)
  • Languages: Python
