Senior Software Engineer

Microsoft's COSMIC team is seeking a Senior Software Engineer to help build and maintain a global scale managed-runtime environment based on Azure Kubernetes Service. This role is part of the M365 organization, specifically working on the COSMIC team that provides a Kubernetes PaaS-like platform for Microsoft Substrate services and developers. The position involves designing and implementing solutions that enable service teams to focus on their business requirements rather than infrastructure concerns.

The ideal candidate will have strong experience in distributed systems, cloud services (preferably Azure), and DevOps practices. You'll be working on critical infrastructure components including deployment, upgrades, security, observability, and debuggability. Knowledge of Kubernetes and Linux is advantageous.

As part of Microsoft's mission to empower every person and organization globally, you'll work in a collaborative environment with a growth mindset. The role offers a hybrid work arrangement with up to 50% work from home flexibility and requires 0-25% travel. You'll be joining a team that values respect, integrity, and accountability while building inclusive solutions that impact millions of users.

The position comes with comprehensive benefits including industry-leading healthcare, educational resources, investment options, parental leave, and generous time off. You'll have opportunities to contribute to giving programs and connect with professionals across Microsoft's global network. This role requires passing Microsoft's Cloud Background Check upon hire and every two years thereafter.
