Principal Security Research Manager

**Overview**

We are building the evaluation backbone for safe, reliable, and efficient agentic engineering in Microsoft Security. This team will create systems that determine when an AI agent, model, prompt, tool, memory strategy, or orchestration pattern is ready to be used in production security and engineering workflows. The role is ideal for engineers who can operate end to end: understand the workflow, design the benchmark, build the harness, implement validators and graders, run experiments, analyze quality and cost tradeoffs, connect results to production feedback, and help teams make evidence-based release decisions.

**Why this role matters** : Microsoft Security is moving toward agentic engineering systems for security triage, remediation, repo readiness, and scan-to-verified-closure workflows. Evals are the trust system for that shift. They help decide whether autonomy can safely expand, whether a release should stop, and which configuration achieves the req...
