> Builds full-stack AI agents for voice/SMS automation in home healthcare, including LLM orchestration, observability, and ops tooling. Strong generalist comfortable with production LLMs, shipping fast in ambiguous startup environment.

## Job Description

## 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.
