The Embedded Software Development Engineer II (C/C++) will join the EC2 Nitro Fairness team, focusing on equitable resource allocation in Amazon's multi-tenant cloud infrastructure. This role involves developing algorithms and systems to manage shared compute, memory, and network resources across customer workloads. The engineer will work closely with hardware teams and hypervisor engineers to implement fairness policies that ensure performance isolation. A deep understanding of virtualization technologies and performance optimization is essential for impacting millions of EC2 instances.
