Job description

We’re hiring founding engineers to help build the infrastructure behind the next generation of B2B software. This is a high-ownership role : you’ll work directly with the founders to shape the product, the company, and the way healthcare and staffing operations are run.

You’ll be among the first employees at an early-stage startup, which means challenge, uncertainty, and opportunity. This role isn’t for everyone — to be a good fit, you need to be hungry to move build, break and push boundaries.

What you’ll do

  • Ship fast, talk to customers, and build at the frontier of AI-native software.
  • Work across the stack — from re‑architecting ML forecasting systems to delivering elegant user-facing features.
  • Build the platform infrastructure that allows AI to generate customer‑specific apps, reports, and workflows.
  • Help define engineering culture and grow the team.

What kind of person we’re looking for

  • You must have already graduated or be graduating by December 2025.
  • High‑energy, opinionated, and fun to work with.
  • Strong product taste.
  • You’ve built real products for real customers, not just internal tools or integrations.
  • You move quickly but maintain a high bar for quality — and expect the same from those around you.
  • You want to help build not just a product, but a company and a category‑defining business.
  • Visa required but open to O‑1 visa sponsorship for exceptional candidates (e.g., top‑20 university, publications, or press). If applicable, please mention how you meet these O‑1 criteria in your application.
  • Tech stack

  • LLMs : OpenAI, Anthropic
  • ML : LightGBM, Prophet
  • Backend : Python, Postgres
  • Frontend : React, TypeScript
  • Infrastructure : AWS
  • #J-18808-Ljbffr
