Overview The Defender for Office 365 product group owns the protection experience for email and collaboration across Microsoft 365. The product management team drives end-to-end ownership across the product lifecycle, partnering with groups and stakeholders across the organization and directly with customers and partners. As part of Microsoft XDR, the product spans real-time detection, post-delivery response and recovery, investigation and hunting, and pre-breach capabilities. The team owns one of the largest security solutions in the XDR portfolio and helps shape how communication and productivity security will work in an era of AI-powered social engineering, using AI to strengthen detection and making MDO the trusted entry point into the broader Defender suite. The group works at the intersection of protection efficacy, explainability and everyday usability, serving SOC analysts, email administrators and end users alike.

Responsibilities Are you a product leader who wants to own a product line that protects organizations every single day, and to build the team that delivers it Come work with us at the largest security company in the world, on one of its most broadly deployed security products. Microsoft Defender for Office 365 protects email and collaboration across Microsoft 365. Attackers are shifting from recognizable malicious artifacts toward adaptive, multi-step social engineering, and generative AI is lowering the cost of personalizing those attacks at scale. Staying ahead of that shift — while keeping protection fast, explainable and operable at enterprise scale, is the challenge this role leads. You will oversee a portfolio of complex engagements while developing high-performing teams and shaping a sustainable security product. You will own the overall health, quality and success of a product line and its features within the MDO portfolio.
