Principal Software Engineering Manager

Security is one of the most critical priorities for our customers in a world increasingly shaped by digital threats, regulatory demands, and complex IT environments. Microsoft’s mission is to make the digital world safer for everyone – by reshaping how security is delivered and empowering every user, customer, and developer with simplified, end-to-end protection across the cloud. We are committed to securing technology platforms, devices, and diverse customer environments, while also protecting our internal estate. Our culture embraces a growth mindset, inspires excellence, and encourages individuals and teams to bring their best every day. Through this approach, we drive innovations that transform lives and create meaningful global impact.

The Identity & Access Management (IAM) Protect team within the CISO organization plays a central role in this vision by managing Entra tenants across the Microsoft Cloud. We design, build, and operate robust security frameworks that enforce policies across thousands of services – safeguarding both Microsoft’s infrastructure and customer environments.

We’re looking for a Principal Software Engineering Manager with deep technical expertise and a strong security mindset to lead our Tenant Security team. This leader will drive the architecture, development, and evolution of systems that enforce policy, protect tenant boundaries, and detect and respond to adversaries. If you are passionate about distributed systems, identity and access management, and building security at scale, we want to hear from you.

• Lead a team of engineers to design, build, and operate scalable security solutions that protect Microsoft cloud tenants from adversarial threats.
• Drive the development of distributed frameworks and platforms that enforce authentication, authorization, and governance policies at scale.
• Collaborate closely with cross-functional teams – product managers, security researchers, and engineering peers – to define requirements and prioritize initiatives.
• Foster a data-driven culture by instrumenting telemetry and using metrics to inform decisions, measure effectiveness, and improve customer outcomes.
• Guide architecture reviews, lead technical discussions, and ensure operational excellence through strong engineering practices and documentation (e.g., design docs, troubleshooting guides).
• Troubleshoot and resolve complex issues across networking, compute, storage, and identity stacks, including live site incidents.
• Coach and develop engineers on the team, fostering a culture of growth, inclusion, and high performance.
