Lead - Product Security Engineer

Rocketlane is a B2B SaaS platform for client onboarding and project delivery, building Nitro, our AI-native product layer on Claude and MCP. We're hiring a Security Lead to own product and infrastructure security end-to-end: setting direction, leading incident response. This is not a compliance-only role. You'll be the person we call when something breaks on a Saturday night, and the person who makes sure it doesn't keep happening.
