Overview
In this role, you will work across the discovery and mitigation of security vulnerabilities – identifying weaknesses in systems, understanding their impact, and helping drive protections that improve the security of Microsoft platforms at scale. You will partner with engineers across Windows, Azure, and platform infrastructure to deliver security improvements and influence the way systems are designed and built. This role is well suited to engineers who enjoy deep systems work, solving complex problems, and delivering high impact security outcomes.
The Microsoft Offensive Research & Security Engineering (MORSE) team is looking for a Senior Security Engineer to help secure Microsoft’s products and devices.
Responsibilities
- Drive identification and analysis of security vulnerabilities across operating system and platform components, including design review, code review, fuzzing, and variant analysis.
- Develop and influence mitigations and protections that reduce risk across platforms, improving resilience against entire classes of vulnerabilities.
- Collaborate with engineering teams to integrate security into the development lifecycle, influencing design decisions and improving secure engineering practices.
- Contribute to the development and scaling of security tooling, detection capabilities, or analysis techniques that enable broader coverage and earlier detection of vulnerabilities.
- Partner across organisations to translate security findings into systemic improvements and measurable security outcomes.
- Stay current on attacker techniques, emerging vulnerability classes, and industry trends, applying this knowledge to improve Microsoft’s security posture.
- Provide technical leadership within and across teams, contributing to direction setting, problem decomposition, and delivery of complex security initiatives.
Qualifications
- Significant experience in security-related elements of software engineering or in another security-related field.
