Senior Software Engineer

As a Senior Software Engineer on the Copilot Security engineering team, you will design and build durable, high‑quality systems that harden Microsoft’s agentic and autonomous AI stack. You will engineer security‑critical capabilities spanning adversarial evaluation infrastructure, telemetry and provenance services, reproducibility tooling, and runtime guardrails that reduce real‑world security risk across Copilot components, and emerging agents. Your work strengthens Microsoft’s cross‑ecosystem security posture by converting threat patterns and XPIA risks into robust, repeatable engineering solutions—advancing the team mission to embed agentic security deeply and consistently across the Copilot architecture. You will collaborate closely with adversarial testing, applied science, and partner security and engineering teams to build secure‑by‑design components, close the loop from attack simulation to defense deployment, and drive measurable improvements in safety, resilience, and system integrity.
