Leveraging Microsoft’s global reach and one of the world’s largest security telemetry sets, you will have a direct, tangible impact on protecting organizations and the global economy. This is an opportunity for researchers who are passionate about transforming security operations and shaping how defenders investigate and stop attacks at scale.\nWe are looking for a Principal Security Researcher to lead research for key agents within Project Perception, part of Microsoft’s broader agentic security evolution. You will lead research for this area end to end, from framing high-impact investigation problems and bringing domain expertise into agents design and evaluation, to partnering with data science, engineering, product, and other teams to move these capabilities into production and customer-facing experiences.\nOur team values diversity and strives to hire individuals with varied experiences and perspectives. We understand that no candidate possesses every desired skill and experience, but together, we form a strong, effective team.\nResponsibilities\nLead security research for agents within Project Perception, from defining high-impact problems and research methodology through agent design, rigorous evaluation, production readiness, and customer-facing experiences.\nSet the research strategy and align partner teams across the organization. Translate research priorities into clear requirements and experiments, use evidence to influence roadmap decisions, and communicate strategy, findings, and recommendations to senior stakeholders.\nDrive research outcomes into production and customer-facing experiences. Partner with engineering, data science, and product teams to define success criteria, validate quality and safety, establish production readiness, measure customer impact, and iterate based on real-world performance.\nAnalyze large-scale data and conduct investigations to improve the quality and effectiveness of Project Perception agents, building on and contributing to Microsoft Defender’s protection knowledge layer.\nApply and champion AI in security research, using current models, agentic architectures, coding agents, and tooling to accelerate triage, investigation, and detection and increase researcher productivity. Validate AI outputs and develop reusable workflows.\nMentor and grow researchers, elevating the team’s technical bar.\nQualifications\nYou have at least 10+ years of experience in security research or a closely related cybersecurity research role.\nStrong, evidence-backed adoption of AI in technical work. Regularly use and develop AI skills, coding agents, agentic tools, or AI-assisted workflows, while evaluating and validating outputs.\nDeep expertise in security research and modern attacker tradecraft, with the ability to conduct complex investigations and translate security knowledge into reliable agent and protection outcomes.\nExperience leading technical work from research and design through production delivery, partnering with engineering and product teams, and influencing roadmaps and senior stakeholders across organizational boundaries.\nProficiency in programming, such as Python or C#, and large-scale query languages, such as KQL or SQL, with experience analyzing security data and developing or validating research and protection capabilities.\nDemonstrated technical leadership through mentoring researchers, raising the quality bar, and communicating complex findings clearly.\nPreferred Qualifications\nBachelor’s, master’s, or doctoral degree in Computer Science, Computer Security, Software Engineering, or a related field; equivalent practical experience is also valued.\nOther Requirements\nAbility to meet Microsoft, customer and/or government security screening requirements are required for this role. These requirements include, but are not limited to the following specialized security screenings: Microsoft Cloud Background Check: This position will be required to pass the Microsoft background and Microsoft Cloud background check upon hire/transfer and every two years thereafter.#MSFTSecurity\n\nThis position will be open for a minimum of 5 days, with applications accepted on an ongoing basis until the position is filled.\nMicrosoft is an equal opportunity employer.
