The role will work closely with engineering teams to ensure that new features, modernization investments, APIs, administrative operations, and service-to-service interactions are secure by design.\nThe role will combine deep expertise in identity, authentication and authorization, privileged operations, API security, distributed systems, and threat modeling with the ability to influence architecture across multiple teams.\nThe broader Substrate Identity and Directory strategy makes customer trust, security initiatives, service hardening, least-privileged access, and reducing privileged dependencies key priorities.\nMicrosoft’s mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.\nResponsibilities\nOwn the security architecture and security design principles across the three IDC areas spanning across authentication, authorization, privilege operations, least privilege access to directory resources, isolation, threat modelling. \nReview major architectural changes, APIs and modernization initiatives for security risks. \nDefine reusable security patterns and guardrails that teams can adopt rather than solving security independently in each feature. \nIdentify systemic security risks that span multiple components and drive architectural solutions. \nEnsure security is incorporated early in engineering design rather than addressed primarily through post-design reviews. \nLead threat modelling for major features and architectural changes. Identify trust boundaries, attack surfaces and potential privilege-escalation paths.\nWork across Provisioning, Groups and Manageability rather than belonging to the security implementation of one component. Partner with identity, authentication/authorization and security organizations. \nHelp design and build AI agents for SFI workflows such as finding and fixing compliance issues, collecting evidence, inventorying and rotating secrets, enforcing configuration rules, and triaging work items etc. \nQualifications\nRequired/Minimum Qualifications:\nBachelor's Degree in Computer Science or related technical field AND 6+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python.OR equivalent experience.\n\nAdditional or preferred qualifications\nOther Requirements: Ability 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:\nMicrosoft Cloud Background Check: This position will be required to pass the Microsoft Cloud background check upon hire/transfer and every two years thereafter. \nPreferred Qualifications:\nBachelor’s degree in computer science or related technical field AND 10+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python.\nSolid experience designing and securing large-scale distributed/cloud services. \nDeep understanding of identity, authentication and authorization. \nSolid understanding of least privilege, defense in depth, trust boundaries and secure-by-design principles. \nExperience designing or reviewing service-to-service authentication and authorization. \nExperience with application/service identities, certificates, credentials and secrets. \nExperience conducting threat modeling and architecture security reviews. \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.
