About the role

The Microsoft Red Team (MRT) attacks Microsoft services to identify security risks and help improve protection, detection, investigation, and response. The role is a Principal individual-contributor focusing on telemetry, detections, monitoring, deconfliction, and operational infrastructure surrounding Red Team engagements, rather than executing engagements.

Responsibilities

  • Define and drive the technical strategy and architecture for Red Team visibility, telemetry, detection, deconfliction, and operational security.
  • Use live Red Team operations, security incidents, threat intelligence, and adversary activity to identify systemic visibility and control gaps and translate them into prioritized engineering investments.
  • Architect and build scalable services and data pipelines that collect, normalize, enrich, and correlate Red Team telemetry to make the right signals available to defenders.
  • Drive the development of monitoring, hunting, detection, and alerting capabilities that help contextualize Red Team activity, identify unexpected or unauthorized behavior, and distinguish authorized operations from genuine adversary activity.
  • Build durable deconfliction capabilities that combine operational context, asset and identity information, infrastructure signals, and behavioral telemetry while protecting sensitive Red Team information.
  • Own and evolve the authoritative inventory of Red Team operational assets, ensuring infrastructure, tooling, identities, and related metadata are accurate, automated, auditable, and usable by monitoring and deconfliction systems.
  • Raise the engineering bar across Red Team systems through strong patterns for testing, reliability, observability, secure development, deployment, and infrastructure lifecycle management.
  • Provide hands-on technical leadership through architecture, implementation, reviews, debugging, operational response, and mentorship, while influencing engineering teams and roadmaps across Microsoft.
  • Help ensure Microsoft can conduct authentic Red Team operations with strong visibility, control, and confidence in its defensive response.

Qualifications

  • Bachelor's Degree in Computer Science or related technical field AND 6+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python OR equivalent experience.
