You'll design and ship full-stack systems, shape platform capabilities to empower hundreds of product teams, and directly contribute to the development of the most impactful AI agents.

Flagship Agent: UpToDate Expert AI

In Health, we're launchingUpToDate Expert AI-a medical research and clinical reasoning agent that transforms the world's most widely used pointofcare knowledge resource into a realtime medical assistant. Millions of physicians will rely on it to accelerate differential diagnosis, refine treatment decisions, and reduce cognitive load-while maintaining rigorous safety, privacy, and guideline fidelity. Improvements you ship (latency, reliability, hallucination reduction) will translate directly into faster, higher-quality patient care at global scale.

Tech stack

You don't need to know all of these on day one, but you should be ready to learn quickly.

• TypeScript, Node.js, React, Python, LangChain/LangGraph, MCP/A2A, Rust
• AWS (primary), Azure, GCP; Docker, Terraform, GitHub Actions
• DocumentDB, DynamoDB, OpenSearch, Azure AI Search
• Azure OpenAI, AWS Anthropic, Google Gemini
• GitHub, Confluence, Slack

What you'll do

• Design and implement fullstack applications, AI agents, and platform components that enable rapid GenAI agent development, validation, and deployment.
• Build developer tooling, CI/CD, and observability for safe, fast iteration (evals, canaries, rollout/rollback, cost and quality telemetry).
• Apply secure SDLC and privacybydesign practices (threat modeling, least privilege).
• Collaborate with product, UX, and domain experts to deliver customerfocused solutions with measurable outcomes.
• Apply current LLM patterns (RAG, retrieval, routing, tool-use, evals) to deliver measurable customer value-faster, more reliable AI systems; reduced time-to-decision; improved trust/safety metrics; and lower cost per query.
• Lead by example through writing high-quality, maintainable code that demonstrates engineering craftsmanship.

Team context
