About the Role

This role involves building and shipping components of multi-agent systems and RAG pipelines for client engagements, contributing to prompt engineering, tool design, and deployment of production AI systems.

  • Help translate client requirements into technical tasks
  • Build observability into the systems you ship
  • Independently own a workstream (an agentic pipeline, a RAG system, or an eval framework) end-to-end, and present your own architecture decisions to internal and client stakeholders (Senior level)

Requirements

  • Solid Python and/or TypeScript/React fundamentals
  • Some hands-on exposure to LLM application development: RAG, tool use, prompt engineering, or agent orchestration

  • Comfort with ambiguity and a fast pace
  • Willingness and ability to learn quickly in a client-facing, consulting-style environment
  • Production experience preferred for LLM application development; strong coursework/side-project depth considered for Associate level
