Senior Lead GenAI Engineer

Role: Lead GenAI Engineer (Senior Role)

Location: Bay Area, CA (2-3 days onsite/week)

Duration: 6+ Months

Pay Rate: $80 to $90

Overview: Focus: Agentic Content-Application Architecture and Orchestration. The goal is to design and build a stateful, headless GenAI application that helps commercial marketers create grounded and personalized content. The application will coordinate multiple agents and enterprise services, maintain conversational and project state, and generate structured JSON or HTML content blueprints that downstream platforms can assemble into finished assets. This is a hands-on senior contractor who must propose the architecture, make key technical decisions and code critical components—not a coordination-only lead.

Must Haves: Python, TypeScript, Amazon Bedrock, AgentCore, Multi-Agent Orchestration, RAG
