About this role

Overview <div>Microsoft Security is seeking agent and systems red teamers to join a new red team spanning agent security, offensive security, cloud identity, attack automation and adversarial AI. You will conduct hands-on red teaming of agentic systems and AI-enabled security products; design realistic attack chains across models, tools, identities, permissions and isolation boundaries; and turn critical findings into durable improvements such as regression evaluations, automated attack suites, stronger controls and safer product designs. We are looking for a Senior Security Researcher - Red Team to join the team! These are individual-contributor roles for security researchers and engineers who can move between exploitation, systems analysis and AI-specific attack techniques. Success requires depth in offensive security or agent security, fluency across cloud and AI systems, and the judgment to produce reproducible evidence that engineering, product, security and independent review teams can act on. </div> Microsoft’s mission is to empower every person and every organization on the planet to achieve more.
