Job Description
Microsoft 365 Intelligent Conversation and Communications Cloud (IC3) powers billions of real-time customer conversations every day across Microsoft Teams, Dynamics, Azure Communication Services, and third-party solutions. The AEGIS team is the security and privacy backbone of IC3. Our mission is zero-click compliance — automatically identifying and remediating security and compliance risks at scale, so IC3 services stay resilient, trusted, and compliant for highly regulated industries and global enterprises. AEGIS is a centralized security engineering force embedding security-by-design across hundreds of microservices, acting as first responders to incidents, pen-test findings, and compliance gaps, while driving the Secure Future Initiative (SFI) and modern security controls across IC3. A growing part of our charter is building AI-driven, agentic security tooling — agents that detect vulnerabilities, continuously assess posture, triage findings, and drive (or auto-apply) remediation at cloud scale. IC3’s security surface is expanding faster than our senior technical ownership capacity, creating a material risk to consistent execution. A Principal IC security role is needed to provide the architecture depth, review rigor, quality gates, compliance judgment, and partner alignment required to keep security standards consistent across services and platform initiatives. This role is the senior technical anchor for AEGIS — setting the bar for how IC3 designs, ships, and operates secure systems, and acting as the trusted authority partner teams across IC3 and M365 rely on for the hardest security and compliance calls. As a Principal Software Engineer, you will own the multi-year technical strategy and architecture for AEGIS’s security platforms and AI agentic systems, raise the engineering and security bar across IC3 through design and code review, codify quality gates and SFI controls into reusable engineering systems, and drive alignment with security architects, MSRC, compliance, and service-owner leaders so that the security posture of IC3 advances as one program rather than dozens of disconnected efforts. This position is based at the Redmond campus with 3 days per week work in the office and 2 days per week work from home. Relocation assistance is available.
