What the role involves

The AI Operating System for Healthcare

Healthcare runs on legacy software that was last updated a decade ago. Systems don’t talk to each other. Interfaces lag. “Automation” means someone copy-pasting data between tabs.

At Arini , we’re leap-frogging the SaaS era. No more EHRs, no more outdated dashboards, just agents and a database. We’re building the AI operating system for healthcare systems , starting with dental enterprises. Our platform automates phones, scheduling, insurance verification, and workflows across the stack.

We partner with the largest healthcare enterprises, understand their bottlenecks, and build well architected system to optimize their operations.

The Team

We’re a small, elite team of builders and operators who move fast and own outcomes. Our team comes from Meta, SpaceX, Tesla, MIT, Berkeley, Harvard, and other YC startups and were previously founders who’ve built and exited healthtech companies.

We’re obsessed with reliability, real impact, and replacing slow legacy systems with software that just works.

The Role

You’ll build the infrastructure that lets millions of autonomous agents run reliably and serve the healthcare industry at scale.

This is the backbone of Arini: scalable event pipelines, multi-tenant voice infrastructure, high-availability APIs, and the agent runtime layer. You’ll own systems end-to-end: architect, build, ship, measure ROI.

What you’ll do

Design and scale the backend systems powering millions of patient interactions.

Build the event-driven architecture for voice, scheduling, and data ingestion.

Optimize performance, cost, and observability across services.

Own reliability, latency, and uptime across the stack.

Preferred Qualifications

Senior/Staff level experience building and scaling infrastructure

Passionate about building infra that’s simple, predictable, and elegant.

Experience with data warehousing and pipelines

Benefits

Competitive salary with meaningful equity

Free health, dental, and vision insurance

Free in-office lunch and dinners

Unlimited PTO

About Arini

At Arini, we’re building the operating system for dental groups. Phones are the backbone of dental operations — 80% of appointments are still booked over the phone — yet practices miss 20–30% of inbound calls. That’s millions in lost revenue every month. Patient engagement is the biggest bottleneck to growth in dentistry, and we’ve built the most comprehensive AI-powered patient engagement suite in the industry. Arini manages calls, texts, and bookings. We’re going after a $220B, overlooked industry that still runs on legacy systems and outdated workflows. Arini is bringing AI to every part of the dental stack.
