Principal Security Operations Engineer

Quantum computing has the potential to massively accelerate science and technology innovation. Microsoft Discovery & Quantum is building advanced computing platforms, spanning HPC, AI, and quantum, to realize that future. You will join the Quantum Security & IT Operations (QSIT) team protecting a globally distributed research community and its intellectual property. 

As a Principal Security Operations Engineer in QSIT, you will own the response to cybersecurity, external & insider threat incidents affecting Microsoft Quantum, from initial detection and severity assessment through containment, recovery, root-cause analysis, and executive closure working across National Security Team, HR, Legal, Global Trade, and CISO organizations. You will set the technical direction for incident handling, coordinate responders across Quantum and Microsoft security organizations, and ensure lessons learned translate into durable improvements to controls, detections, and operating procedures. 

You will also define and drive the requirements for an AI-enabled QSIT Security Operations Center, shaping how AI supports signal enrichment, triage, investigation, response, and analyst decision-making while maintaining strong auditability and data-handling controls.  

This role requires broad technical and risk judgment, independent leadership in ambiguous situations, and the ability to influence security strategy across organizational boundaries. This role is onsite in Redmond, WA. 

Microsoft’s mission is to empower every person and every organization on the planet to achieve more. As employees, we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.
