Security Researcher, AI Security
Everyone is racing to build on AI. Far fewer people are pulling it apart to see how it breaks. That's our work, and we get there before attackers do.
This role is part of our company's AI Security pillar. We research the AI systems the whole industry is rushing to adopt: the agents and frameworks heading into production, and the runtimes and infrastructure beneath them. The work is deep and hands-on.

Key Responsibilities
Research the security of AI systems end to end, from the agents and frameworks they're built on to the runtimes and infrastructure that run them

Understand the defenses modern systems lean on, and how to get past them
Share what you find, through coordinated disclosure and conference talks.
