AI & Browser Automation Engineer — Brooklyn, NY

About NSSRB4yd

NSSRB4yd builds AI agents that run the back office for enterprise teams: billing, intake, authorizations and phone calls, working inside the systems companies already use. We're starting in healthcare, where one billing mistake means a denied claim and months of lost revenue. We're live with our first customer and an early team in New York.

The role

You'll build the agents themselves: the automations that log into real portals, read what's on the screen, fill out claims and authorizations, and know when to stop and ask a human. You'll work closely with the founders and our billing experts to turn messy real-world workflows into agents that run reliably every day.

What you'll do

• Build browser-automation agents that work in real healthcare portals and payer sites

• Combine LLMs with deterministic checks so agents catch mistakes before they cost money

• Handle the hard parts: logins, timeouts, page changes, retries and edge cases

• Build tools to test, replay and monitor agent runs

• Sit with customers to learn the workflow before you automate it

You might be a fit if you

• Have shipped browser automation in production (Playwright, Puppeteer, Selenium or Stagehand)

• Write solid Python or TypeScript

• Have built with LLMs and know where they fail

• Like debugging why something broke at 2am and making sure it never happens again

• Want to be early and own real work from day one

Nice to have

• Healthcare billing, claims or EHR experience

• AWS experience

• Built AI agents or computer-use systems before

What we offer

• Real ownership from day one

• In person in Brooklyn
