  • Design and implement production-grade agentic AI workflows using open frameworks such as LangGraph, CrewAI, proprietary cloud-based agentic platforms, including agent orchestration, AI gateways (i.e. MCP, A2A), observability, controls and guardrails.
  • Build and optimise retrieval pipelines for Retrieval Augmented Generation (RAG) and agentic workflows, including chunking strategies, embedding models, vector store integration, and re-ranking to ground agent outputs in accurate, current enterprise data.
  • Develop and integrate Generative/Agentic AI solutions using large and small language models (LLMs and SLMs).
  • Build evaluation frameworks to measure AI solution quality, consistency, and implement telemetry and monitoring to track model drift, latency, output quality, and cost metrics in production.
  • Implement best practices for MLOps, LLMOps, across experimental and production environments, including AI pipeline and microservices deployment into cloud environments, APIs, CI/CD, ensuring high availability and low latency.
  • Build AI governance and responsible AI controls for AI systems

  • Experience in API integration and development.
  • Consulting or professional services experience is strongly preferred.

Skills and Attributes for success:

  • Deep experience designing and building agentic AI systems in enterprise environments.
