About the Role

Join a focused pod building two tightly-coupled capabilities for Humana's internal users: an Internal Agentic Search Engine and a Perplexity-Style Front End. You will build agentic pipelines, design retrieval and orchestration layers, and implement tool-use for accurate, cited, and trustworthy answers. You will also deliver a fast, intuitive, conversational search experience, partner across the stack to connect the backend to a responsive UI, and instrument usage and feedback signals.

Responsibilities

  • Build hands-on, end to end, shipping agentic AI features into production.
  • Engineer agentic systems, developing planning, retrieval, tool-use, and orchestration components.
  • Integrate agents reliably and securely with numerous internal and enterprise data sources.
  • Build, deploy, and operate solutions natively on Google Cloud (Vertex AI, GKE, BigQuery, Cloud Run, and related services).
  • Contribute to the Perplexity-style front end for fast, grounded, well-cited answers.
  • Own quality and evaluation by establishing evals, guardrails, observability, and feedback loops.
  • Collaborate on-site in the NYC Mid-Town office Tuesday through Thursday, pairing closely with the pod and Humana stakeholders.
  • Operate with urgency in a fast-moving engagement, iterating quickly and driving outcomes.

Requirements

  • Strong, current software engineering fundamentals with clean, tested, production-quality code (Python strongly preferred).
  • Demonstrated, hands-on experience building agentic AI systems (agents, tool-use, planning, multi-step reasoning, RAG/retrieval).
  • Deep expertise with the Google Cloud technology stack (e.g., Vertex AI, GKE, BigQuery, Cloud Run, Cloud Storage, IAM).
  • Experience integrating LLM applications with numerous, heterogeneous data sources (APIs, databases, document stores, search).
  • Experience taking ML/GenAI systems to production, including deployment, scaling, monitoring, and reliability.
  • Ability to work on-site in NYC Mid-Town 3 days per week (Tuesday–Thursday).
  • Breadth of knowledge across frontier models (e.g., Gemini, and other leading LLM families) and when to use which.
  • Hands-on experience with open-source agentic and LLM frameworks (e.g., LangChain, LangGraph, LlamaIndex, or similar).
  • Front-end / full-stack exposure to help deliver a Perplexity-style user experience.
  • Experience with evaluation frameworks, guardrails, and responsible-AI practices.
  • Prior experience in regulated or enterprise environments (healthcare a plus).
