Hi, we're Oscar. We're hiring a Staff Security Engineer, GRC to join our Information Security Team.

You will operate as a senior subject matter expert who can partner directly with engineering, security, legal, compliance, product, and CMS-facing stakeholders to keep regulated platforms audit-ready while enabling secure delivery.

You will report into the CISO.
