Senior Security Researcher

We are Cloud Threat protection Research team within Microsoft Threat Protection, working at the heart of how Microsoft protects cloud and AI workloads at global scale. Our research directly informs and powers protections in Microsoft Defender, where we study real attacker behaviour, analyse production incidents, and design defences that protect some of the world’s largest enterprises, governments, and critical infrastructure. The problems we work on are current, complex, and high‑impact—rooted in how modern cloud platforms are actually attacked and defended. Our culture is trust‑based and impact‑driven. Researchers on the team have meaningful ownership over their work, the freedom to challenge assumptions, and close collaboration with product and engineering partners to ensure ideas translate into protections that ship and scale. The team brings together globally recognized cloud security researchers and AI experts—highly skilled, passionate professionals committed to continuous innovation and customer protection in an ever‑evolving threat landscape. We value technical depth, clarity of thinking, and customer empathy, and we actively support growth through mentorship, technical leadership, patents, publications, and cross‑team and geo collaborations. If you’re motivated by solving hard security problems, seeing your work make a real difference in production systems, and growing alongside strong peers, this is a team where you can do the best work of your career.
