About The Position

We are scaling from 500 to 2,500 employees over the next year while integrating multiple acquired entities. Our IT infrastructure needs to match the speed of an AI company—not the bureaucracy of traditional healthcare. We're insourcing IT operations and building a unified, secure platform across all business units. This means consolidating fragmented systems, hardening security and compliance, and creating the infrastructure that lets our clinical and AI teams move fast without breaking things. Think of it as a blend of defensive design, greenfield architecture, and frictionless operations security. You'll be one of the earliest members of our internal IT team, working directly with leadership, engineering, and operations to build the infrastructure foundation that powers care delivery across the USA. This role is designed for you if you have a low ego, love solving problems that matter, and are ready to build infrastructure for an industry-changing company.
