Corner Health•Santa Monica, CA

About The Position

Corner Health is an early-stage technology company building the operating system for independent primary care. We give Nurse Practitioners (NPs) everything they need to start and run their own practices — from billing and insurance infrastructure to AI-powered workflow automation. We’re positioned to be the fastest growing in-person primary care company ever. Corner Health was co-founded by Lava Sunder and Anne Gifford and has raised a Series A backed by top investors, as well as the founders of DoorDash, Commure, Grow Therapy, Kindred, Culdesac & more. About the Role We're looking for a senior backend engineer to help build and scale the core infrastructure behind Corner's practice operating system. Today we process thousands of appointments per week across a growing network of independent practices. Behind each appointment is a web of interconnected systems — insurance eligibility checks, patient intake orchestration, claims submission and lifecycle management, payment reconciliation, and provider payouts. These workflows involve coordinating across EHRs, clearinghouses, and payment processors, each with their own quirks and failure modes. Some of the problems you'd work on: Intake orchestration : Our pre-appointment flow handles patient texting, intake form completion, and follow-up cadences — with edge cases for same-day and next-day bookings where the standard timing doesn't apply. This is a real state machine problem with a lot of nuance. Claims and billing infrastructure : Building reliable, high-throughput services for the full claims lifecycle — from eligibility verification through submission, adjudication tracking, and remittance processing. Analytics and observability : Designing our data layer so we can actually measure what matters — tracking KPIs like insurance failure rates, surfacing trends across practices, and making sure the backend is shaped in a way that makes improvement measurable. We need someone who thinks about data shape and accessibility as a first-class concern. Workflow automation : Designing and extending orchestrated, multi-step backend workflows that reduce administrative burden for providers and improve the accuracy and speed of reimbursements. You'll work closely with product and operations to translate complex, real-world healthcare workflows into scalable, intelligent infrastructure. As one of our first engineering hires, you'll work directly with the co-founders, have real ownership over the product, and help shape both the codebase and the culture.
