Gen AI - Data Engineer with AWS Experience

Capgemini is seeking a contract Gen AI - Data Engineer with AWS experience to architect, build, and scale AI-powered “Store AI Agents” that support store operations. The role blends hands-on development with technical leadership across agentic AI, RAG, and production-grade AWS delivery.

Responsibilities

• Own end-to-end architecture and implementation of Store AI Agents.
• Design agentic workflows that connect LLMs with APIs, databases, backend services, enterprise applications, and MCP servers.
• Build and optimize RAG solutions, including embeddings, retrieval, vector search, grounding, and context management.
• Define onboarding and integration processes for new AI agents, covering testing, deployment, monitoring, and production readiness.
• Establish a clear system architecture that separates LLM reasoning and generation from deterministic backend services.
• Leverage Lakehouse and Medallion architecture (Bronze, Silver, Gold) to enable AI and data use cases.
• Define scalable approaches for AI and RAG testing, validation, observability, and performance optimization.
• Handle production challenges such as latency, context limitations, retrieval quality, scalability, and reliability.
• Provide technical leadership across AI and ML, data engineering, cloud, application, and business teams.

Requirements

• Proven experience delivering at least one end-to-end LLM, RAG, or Agentic AI project.
• Strong architectural and hands-on experience with Generative AI on AWS.
• Hands-on knowledge of LLMs, RAG, embeddings, vector search, and agentic workflows.
• Experience integrating AI agents with APIs, databases, backend services, and enterprise systems.
• Understanding of MCP (Model Context Protocol) and agent-to-tool or service integration.
• Experience with Lakehouse and Medallion Architecture, including data pipeline optimization.
• Strong understanding of AI testing, observability, security, scalability, latency, and production performance.
• Ability to articulate end-to-end architecture, including technology choices, integration patterns, and design trade-offs.
