Staff/Senior Platform Engineer

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 No more EHRs, no more outdated dashboards, just agents and a database.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

About the company

Arini is building the single platform to run all healthcare operations.

Healthcare has spent the last decade consolidating, but operations are still fragmented, manual, and expensive. A large group runs dozens of disconnected systems for scheduling, billing, insurance, payables, and reporting, with people moving data between them by phone, fax, and spreadsheet.

We partner with some of the largest healthcare enterprises in the country through a Forward Deployed Engineering model. Engineers sit with the customer, find their biggest operational problems, and ship systems that solve them end to end. The best of that work becomes the platform that scales across enterprises.

Our goal is to deliver the operating leverage healthcare consolidation has promised for decades, so providers can focus on patient care. We obsess over improving patient outcomes, and we are building the platform to run all operations for a $620B industry.
