About the role

What You'll Build

  • Voice and SMS agents that automate the 24/7 shift lifecycle (confirmations, clock-ins, notes, last-minute coverage)
  • LLM orchestration across prompt engineering, tool use, context management, and evals that keep agents reliable as we scale
  • Internal ops tooling so our team can monitor agent performance, handle edge cases, and onboard new customers fast
  • Reliability and observability improvements across our voice and messaging infrastructure
  • Full-stack features from data model to API to UI, shipped to real customers within days

Your First 90 Days

Month 1: Ship something real. You'll pair-program with the team immediately and ship features within your first week. By the end of month one, you'll own a complete feature from design to production.

Month 2: Go deep on the orchestration layer. You'll improve reliability and observability across our voice and messaging stack, and contribute to how we evaluate agent quality at scale.

Month 3: Take ownership. You'll scope and lead a feature area yourself, such as a new EHR integration, an improvement to the talent agent product, or better tooling for our ops team.

Our Tech

  • React / TypeScript / Vite on the frontend
  • FastAPI / Python on the backend
  • Postgres (RDS)

  • You're comfortable with ambiguity and figuring things out as you go
  • You've worked with LLMs in production (or are eager to)
  • You want to be early at a company that's growing very quickly
