You will work to Secure Architecture. You will help architect, build, test, and deploy Oscar's application security systems and processes.

You will work on AI Integration & Security. You will design security measures for AI-driven workflows, specifically integrating security reviews into AI agent processes that bypass traditional ticketing.

You will report into the Manager of Product Security.
