Application Security Engineer

About Candid HealthIn simple terms, healthcare in the U.S. has a massive, invisible problem behind the scenes: getting doctors paid by insurance companies is notoriously complicated. Insurance rules are constantly changing, and every bill (or "claim") requires mountains of paperwork. When mistakes happen, bills get rejected, patients end up with unexpected charges, and healthcare providers waste billions of dollars and countless hours on administrative bureaucracy instead of focusing on patient care. That is where Candid Health steps in. Founded by former Palantir leaders who experienced these pain points firsthand, we are building the modern financial backbone for American healthcare. Instead of relying on decades-old legacy software or attempting to patch broken systems with superficial tools, we've rebuilt the underlying infrastructure from the ground up.Our core product is an autonomous Revenue Cycle Management (RCM) platform. Powered by AI agents and a configurable rules engine, the platform unifies clinical, billing, and insurance data into a single smart system. It acts like an intelligent, automated back-office that handles complex medical claims from start to finish—submitting them accurately on the first pass, cutting down administrative costs, and dramatically increasing cash flow for healthcare providers.Today, we are trusted by over 200 fast-growing healthcare organizations—from digital health innovators to large enterprise medical groups—processing billions in claims annually. Backed by top investors like Sixth Street Growth, Oak HC/FT, 8VC, and Y Combinator, Candid Health recently raised a $120 million Series D to fuel the AI-driven transformation of healthcare payments and eliminate administrative friction for good.Role OverviewWe are looking for a Product Security Engineer to join our team and act as a champion for security within our product engineering organization.
