Principal Software Engineer - ARM

Azure Resource Manager (ARM) is a core service that supports Microsoft’s cloud. Nearly every customer action in Azure, including resource creation, updates, configuration changes, and management through the Portal, CLI, SDKs, and automated workflows, relies on ARM’s API layer and orchestration logic. Because of this responsibility, the service must remain predictable, resilient, and consistent across all regions and resource types. We are hiring seasoned engineer to help evolve ARM’s architecture as Azure continues to grow. The work focuses on distributed systems challenges that appear in large scale, long running platform services. ARM’s scale and central role require careful reasoning about concurrency, failure modes, caching behavior, operational safety, and long-term maintainability. Security is a core requirement for ARM. The service must ensure that all resource operations are properly authenticated, authorized, and auditable. This includes cooperating with identity systems, ensuring secure request handling paths, and validating behavior across the platform. Experience working on authentication or identity related systems is useful because many control plane decisions intersect with security boundaries and access patterns.
