We're looking for hungry, high-throughput generalist engineers as we scale into the multi-millions over the next 6 months.

About You

We're looking for hungry, high-throughput generalist engineers as we scale into the multi-millions over the next 6 months. You might want to start your own company one day, but aren’t sure what to build yet. You might have spent time at a larger unicorn and want to join a fast growing startup with PMF.

You will:

• Get a clear view into engineering, product, go-to-market, and the iterative loop that connects all 3

• Learn the Vertical AI playbook

  • how to embed into an industry, learn the domain, and build LLM-driven workflows to automate it.

  • How to generate demand with modern GTM techniques across B2B and B2C

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)

• Twilio for voice and SMS

• LLMs throughout

• AWS

• Linear, Notion
  

You're a Good Fit If

• You're a strong generalist who can work across the stack

• You stay on the cutting edge of AI dev workflows and love using coding agents to automate engineering, observability, and the entire development workflow.

• You ship fast and iterate based on real usage

• 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

What We Offer

• Interesting, high-leverage work at a company growing very fast

• $180k+ base salary with above-market equity

• Small team where your work ships to customers immediately

• In-person in NYC - we work in the same room

• Multiple second-time founders to learn from - Justin (CEO) sold Bayes (YC S19) to Airtable. Dave built and sold Kamana, an app for travel nurses.
