Overview

The Microsoft Threat Intelligence Center (MSTIC) has unique optics into end-to-end attacks and how different stages manifest across our telemetry: we join the dots and show the art of the possible. The Threat Intelligence Product Research team researches and develops new detection capability through novel correlation and analysis ideas, embeds Threat Intelligence, and then achieves global impact by partnering across the company to make these a reality in customer-facing security solutions. We’re recruiting a Principal Security Researcher with deep expertise and a track record of successful security research delivery to tackle hard problems related to the discovery of threat actors targeting Microsoft and its customers. You’ll be working to analyze vast amounts of telemetry from multiple different products then designing and prototyping detections and disruptions to protect millions of customers. You’ll also be working closely with the threat intelligence analyst community to build new insights and automate tracking of threat actors through your deep expertise in security product and platform internals. Security Research is a broad field, and we welcome interest from accomplished security researchers with a wide variety of prior expertise. Our primary focus is on threat intelligence-based detection through analysis of telemetry sent to the cloud or generated by internal cloud services – so a desire to work at that level and build guru-level knowledge of Kusto and KQL is essential. Our current areas of focus are related to Identity, Cloud Apps, and Microsoft Cloud, but there is scope to research and join activity over a wide range of technologies and data sources.

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.
