If You’re Tired of Shipping Code That Doesn’t Matter — Build Something That Fixes Healthcare Payments

What’s in it for you

You’ll be one of the first engineers in a startup that’s already secured $6.5M in funding — which means stability and the freedom to shape things your way.

From day one, you’ll:

  • Build features that go straight into production (no endless backlog limbo)
  • Work directly with the CEO and Director of Engineering — your ideas won’t get lost in layers
  • Own problems end-to-end, from customer feedback to deployment
  • Help define the engineering culture, standards, and architecture

Which means… you’re not just writing code — you’re building a platform and a company around it

What you’ll be doing (and why you’ll enjoy it)

  • Designing and shipping full-stack features using React, TypeScript, and Node.js
  • Turning messy, complex healthcare data into clear, actionable insights → So your work actually solves real-world problems, not just technical ones
  • Shaping architecture decisions early → Which means no legacy headaches later
  • Collaborating closely with leadership on product direction → So you influence what gets built, not just how

Where you’ll be doing it

A mission-driven startup tackling one of healthcare’s biggest inefficiencies: payments.

Quick story:

  • Healthcare payments are notoriously complex and error-prone
  • Billions are lost annually due to inefficiencies
  • Building a payment intelligence platform to change that

With $6.5M already raised, you’re joining at the point where:

  • The risk is reduced
  • But the opportunity to shape everything is still wide open

What you’ll need

  • 3+ years as a Full-Stack Engineer (with a backend lean)
  • Strong experience with React, TypeScript, and Node.js
  • Confidence working in fast-moving environments where priorities shift
  • The ability to break down complex data and systems into something usable

Bonus points if you:

  • Have worked in HealthTech or Fintech
  • Have been an early or founding engineer before

What you’ll get (beyond the obvious)

  • Real ownership — your work directly impacts the product and users
  • A seat at the table for technical and product decisions
  • The chance to build something meaningful in healthcare (not just another SaaS tool)
  • A fast-moving environment where good ideas get shipped — not buried
