The primary location for this position is San Diego, CA.Do you want to shape the future of virtualized (SDN) networking in the world’s biggest public cloud?The Amazon Elastic Compute Cloud (EC2) VPC Packet Pipeline team owns the packet pipeline that runs right beneath all our customer's EC2 VPC instances, adding features like firewalling (security groups), billing and monitoring as we touch every single packet on every single host across our massive worldwide fleet. Our vision is to combine the performance of bare metal networking while maintaining all the benefits of the cloud, including delivering features not possible on bare metal i.e. true Software Defined Networking (SDN).We are growing fast, and are looking for kernel/embedded C leaders who can deliver ultra high performance – our goal is to be processing millions of packets per second on a CPU core.
