The Microsoft Threat Experts team is looking for threat hunters! No matter how sophisticated attacker behaviors become, Microsoft Threat Protection (MTP) will help enterprises detect, investigate, and respond to advanced attacks and data breaches on their networks. Our team uses deep knowledge of the attacker landscape and rich telemetry from our sensors to perform root-cause analysis and generate custom alerts, ensuring that MTP customers are well equipped to quickly respond to human adversaries identified in their unique environments.

Ensuring that no human adversary can operate silently begins with experts harnessing the powerful optics provided by MTP, across the attacker kill-chain, coupled with world-class detections.  We’re looking for a skilled hunter to harness the power of Microsoft’s trillions of security signals to quickly identify and report the latest human adversary behaviors, drive critical context-rich alerts, build new tools and automations in support of hunting objectives, and drive innovations for detecting advanced attacker tradecraft.





  • Explore and correlate large data sets to uncover novel attack techniques, monitor and catalog changes in activity group tradecraft, and generate custom alerts for enterprise customers.
  • Work with customer support teams to support investigation and response during an enterprise’s time of need.
  • Collaborate with our data science and threat research teams to develop and maintain accurate and durable cloud-based detections.
