Job description

The Senior Security Researcher role on the Microsoft Threat Protection Research Purple Team focuses on emulating real-world threat actors to enhance cybersecurity measures. This position involves designing and executing adversary simulations across various environments, including endpoint and cloud. The team aims to leverage AI-driven workflows to improve attack simulations and enhance detection capabilities. The role requires collaboration with blue team members and the development of offensive tooling to replicate modern attacker techniques.

Requirements

  • Doctorate in Statistics, Mathematics, Computer Science, Computer Security, or related field, or equivalent experience.
  • Master's Degree in Statistics, Mathematics, Computer Science, Computer Security, or related field AND 3+ years of experience in relevant fields.
  • Bachelor's Degree in Statistics, Mathematics, Computer Science, Computer Security, or related field AND 4+ years of experience in relevant fields.
  • 5+ years of incident response, threat hunting, and/or SOC experience.
  • Experience leveraging and producing threat intelligence at the campaign or actor level.
  • Knowledge of MITRE ATT&CK and threat modeling methodologies.
  • Security related certifications such as GCIA, GMON, GCIH, CISA.
  • 3+ years of experience with coding.
  • Experience in classical and deep learning machine learning methods.

Responsibilities

  • Design and execute adversary simulations that emulate real-world threat actors across various environments.
  • Develop and modify offensive tooling, including custom payloads and command-and-control frameworks.
  • Conduct malware development and tradecraft research to replicate modern attacker techniques.
  • Leverage threat intelligence to inform adversary emulation scenarios.
  • Apply threat modeling frameworks such as MITRE ATT&CK to emulate realistic attack paths.
  • Utilize AI-enabled systems to generate attack variations and automate tradecraft execution.
  • Partner with blue team and detection engineering teams to validate detections.
  • Analyze telemetry generated from simulations to assess detection coverage.
  • Contribute to simulation reports, technical documentation, and internal knowledge sharing.
  • Collaborate across teams to improve offensive tooling and research practices.

Benefits

  • Employees at Microsoft are often offered comprehensive, “world-class” benefits—including health and mental-wellness programs, competitive pay with bonuses and stock awards, and retirement/savings options.
