The AWS Networking organization is looking for a Software Development Engineer to join our Amazon Dedicated Cloud (ADC) Networking team. As a Software Development Engineer on our team, you will build systems that manage mission-critical networks with high availability and low operational overhead. You will work closely with internal and external software development teams to develop new products such as automated switch provisioning, automated event detection, and continuous workflow testing that improve the security and availability of our networks. ADC Networking owns the entire lifecycle - design, build, deployment, scaling, sustaining engineering, and operations - of our networks connecting between and within the data centers for a dedicated customer region, interconnections to customer networks, and the solutions that enable remote access to these regions from secure operations facilities. You will develop, evolve, and optimize these systems, to help protect our customers and provide an improved experience. Successful candidates have experience building highly distributed mission-critical systems, are self-directed, and love to work on challenging and complex problems. You are a passionate coder, who values simplicity of implementation leading to highly maintainable code that is well documented and easy to follow. Experience with computer networking concepts is preferred. This position requires that the candidate selected be a U.S. citizen and obtain and maintain an active TS/SCI with a polygraph.
