Company Description: Adonis - Series C healthcare AI startup backed by General Catalyst

Job Description:
Join a high-caliber team at 3 World Trade Center building AI agents that fix healthcare revenue operations. You will own end-to-end features across a Python, React, and PostgreSQL stack, designing systems that proactively resolve insurance claims. This role is perfect for engineers with product intuition who want to solve a multi-billion dollar problem.

Location: New York, USA

Why this role is remarkable:

• Work at a hyper-growth Series C startup that grew revenue 4x last year and has raised over $95M from elite investors like General Catalyst and Bling Capital.

• Tackle a critical mission fixing the broken US healthcare reimbursement system, directly helping providers recover the 15% of revenue typically lost to administrative friction.

• Join an elite engineering culture at a prime NYC location, working alongside veterans from Google and Cedar with 100% employer-paid benefits and free daily lunch.

What you will do:

• Design, architect, and implement scalable full-stack solutions using Python and TypeScript/React to power autonomous revenue cycle agents.

• Build and maintain robust APIs and complex data pipelines that process healthcare claims data with high precision and performance.

• Partner directly with Product and Design to prototype and ship customer-facing dashboards that provide deep insights into revenue outcomes.

The ideal candidate:

• Possesses 3+ years of production experience with Python, TypeScript/React, and PostgreSQL in a fast-paced software environment.

• Demonstrates strong systems design expertise and the ability to architect efficient, scalable client-facing applications from the ground up.

• Brings domain experience in healthcare technology or revenue cycle management (RCM) from companies like Cedar, Flatiron, or Oscar Health.

We never post fake jobs
This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.
Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
