Lead Generative AI Engineer (Agentic AI, RAG 2.0, Prompt Engineering, AWS)

Job Title: Lead Generative AI Engineer (Agentic AI, RAG 2.0, Prompt Engineering, AWS) Location: Remote / Hybrid Job Type: Contract/Full Time Experience: 10+ years Software Engineering/Gen AI (hands-on required) Sponsorship is not available for this role at this time. We are hiring a Lead Generative AI Engineer to build next-generation AI-native products using the latest advancements in LLMs, Prompt Engineering, RAG 2.0, multi-agent systems, and evaluation frameworks. This role is ideal for engineers who have worked on real-world GenAI solutions building production-grade AI assistants, retrieval systems, autonomous agents, document intelligence pipelines, and secure AI workflows in AWS Environment. You ll work in a fast-moving Emerging Tech environment where innovation, experimentation, and shipping production AI systems are equally valued.

Key Responsibilities

• Design and build GenAI applications with Agentic AI + RAG pipelines
• Implement advanced Prompt Engineering patterns:
• structured prompts, chain-of-thought prompting strategies, self-verification, tool prompting
• Build agent orchestration workflows:
• tool-augmented agents, planner/executor agents, multi-agent collaboration
• Implement RAG 2.0 systems:
• hybrid retrieval (keyword + dense), reranking, chunking strategies, citations/grounding
• Develop backend services using:
• Python microservices and GenAI pipelines
• Build document AI workflows:
• ingestion OCR extraction embeddings indexing retrieval response with citations
• Implement LLM evaluation + observability:
• hallucination detection, quality scoring, groundedness checks
• Integrate model safety and governance:
• guardrails, policy filtering, PII redaction, secure tool usage
• Deploy scalable solutions on cloud with CI/CD, monitoring and performance tuning

Preferred / Emerging Tech Stack (Strong Plus) These are high priority for the Emerging Tech client: Agentic AI / Orchestration
