About the role
As our Application Security Engineer, you'll own how we find, prioritize, and drive down application-layer risk across the consumer flows that put cash offers in homeowners’ hands, the GraphQL APIs that power our products, and the AI agents and vibe-coded tools our engineers ship every week. The job is to make it safe to build fast, not to slow things down.
