Member Of Technical Staff - Security Engineer

• Design and build secure, high‑performance platform components that support Copilot’s agentic workflows across cloud and device environments
• Develop novel security mechanisms for agentic AI systems, including real‑time intent validation, information‑flow controls, isolation boundaries, and abuse‑resistant orchestration
• Eliminate entire classes of vulnerabilities by creating secure‑by‑default APIs, sandboxing layers, and hardened system interfaces
• Build and operate offensive security tooling and agents that continuously probe Copilot’s autonomy, reasoning paths, and trust boundaries
• Partner closely with AI researchers, platform engineers, and product teams to translate research and prototypes into production‑ready security features
• Write high‑quality, well‑tested code across backend services, platform layers, and AI‑adjacent systems
• Use telemetry, signals, and data‑driven analysis to detect abuse, anomalous agent behavior, and emerging threat patterns
• Navigate ambiguity, make sound engineering tradeoffs, and ship iteratively in a fast‑paced product environment
• Contribute to a culture of high ownership, technical excellence, and inclusive collaboration.
