It is a very cool time for software development in the world of networks. Routers are becoming commodity devices. The network operating system that sits on top of these commodity devices must be built. Chip manufacturers have released data plane development kits allowing regular servers to perform essential networking functions if the right software is built. The evolution of big data storage and processing technologies is allowing for deep network analytics software to be developed that is allowing networks to grow in scale and scope. We are taking all the industry trends mentioned above and blending them into the critical foundation of utility computing: the network.
AWS Networking Software Systems team is looking for software engineers to build new systems that innovate in the area of Network Security. At Amazon Web Services, we run one of the biggest networks in the world.
