Key Responsibilities

1. GenAI / LLM Application Development

• Build GenAI applications using:
• LangChain, LangGraph
• Implement RAG architectures with:

• Design prompt-engineering strategies:
• Instruction-following
• ReAct (Reasoning + Acting)
• Chain-of-thought structuring
• Self-reflection and planning loops
• Evaluation Strategy

• • Implement evaluation frameworks for Classical ML and GenAI systems, covering statistical validation, reliability, and robustness.
  • Assess LLM outputs, RAG pipelines, and agent workflows for grounding quality, relevance, and retrieval accuracy (e.g., recall@k, precision@k).
  • Use LangSmith for tracing, automated evaluations, regression testing, and continuous system-level quality monitoring

2. Agentic System Architecture

• Build agentic workflows:
• Tool-calling agents
• Planner-executor systems
• Multi-agent communication systems
• Hierarchical agent architectures
• Deep Agents
• Integrate memory systems:
• episodic memory
• semantic memory
• vector-based long-term knowledge
• Implement evaluation frameworks for agentic systems using LangSmith.

3. Model Context Protocol (MCP) & Tooling

• Implement MCP servers for external tool connectivity.
• Build tools that allow agents to interact with:
• APIs
• Code execution environments
• Knowledge bases
• Company applications

4. Classical ML (Foundational DS Skills)

• Apply ML models to structured/unstructured data.
• Conduct feature engineering, model selection, hyperparameter tuning.
• Build interpretable models where required.

5. Engineering & Integration

• Collaborate with backend engineering teams to seamlessly integrate agentic and GenAI systems into production applications.
• Implement observability, tracing, and monitoring for GenAI workflows using LangSmith to ensure reliability and system-level transparency.

6. Cloud ML-Ops & Quality

• ML Modelling, data drift, concept drift, model quality monitoring.
• Hands-on experience across AWS/ Azure/ Databricks, with flexibility to work on any cloud platform.

• Adhere to stringent quality assurance and documentation standards using version control and code repositories (e.g., Git, GitHub, Markdown)

Skill Requirements

Required Skills & Experience

• 5-10 years total experience, with 2-4+ years hands-on GenAI.

• LangChain, LangGraph
• LangSmith (tracing, metrics, evaluations)
• MCP tooling and agent tool integration
• ReAct, Tree of Thoughts, multi-agent orchestration
• RAG patterns and vector databases
• Strong coding expertise in Python.
• Classical ML foundations (tree models, regression, etc.).
• Experience working with LLM APIs and/or open-source LLMs.
• Experience building and debugging production-quality GenAI pipelines.
• Aws/azure

• GIT Ops
• Prior experience building complex multi-agent systems for real-world applications.
• Knowledge of multi-modal LLMs (vision, speech, code).
• Familiarity with structured evaluation of LLM systems (hallucination tests, safety assessments etc ).
• Experience in enterprise-grade LLM deployments.

Other Requirements

BE or Equivalent degree
