Key Responsibilities

1. Solution Architecture & Technical Leadership

  • Architect enterprise-grade agentic and LLM solutions (single-agent, multi-agent, tool-driven workflows)
  • Define scalable GenAI system design patterns (RAG, orchestration layers, evaluation frameworks)
  • Act as the technical anchor for GenAI initiatives across projects
  • Drive design reviews, architecture governance, and best practices

2. Agentic AI & LLM Engineering

  • Design and build agentic systems using LLMs for use cases such as: 
    • Knowledge assistants
    • Document automation & intelligence
    • Workflow orchestration
  • Implement advanced prompt engineering strategies, prompt orchestration, and reasoning chains
  • Build tool-calling / function-calling frameworks for agent workflows

3. RAG & Retrieval Systems

  • Lead end-to-end implementation of RAG pipelines
    • Data ingestion → chunking → embeddings → vector indexing → retrieval → response generation
  • Optimise retrieval quality (recall, relevance, grounding)
  • Evaluate and benchmark different architectures

4. Productisation & Engineering Excellence

  • Develop production-grade APIs/services (FastAPI, Flask, etc.)
  • Drive code quality, testing standards, and reusable architecture components
