A day in the life:

Engineers in Corporate Network Engineering organization have a wide range of responsibilities: we work with internal partners to develop and implement the next gen platforms along with the tooling ecosystems to support with these platforms driving efficiency and scalability through the automation of builds, configuration deployment, and the scaling of capacity. As our network is one of the largest in the world, there is no blueprint at our scale allowing our engineers to develop solutions to the complex challenges that we face daily. We encourage durable solutions that look around corners while taking into consideration our customer needs from a cost, performance, and reliability perspective. Our team develops tooling that provides the required visibility and control of traffic across the network, while prioritizing the automatic mitigation of events to minimize the impact to our customers.

Work in a 24x7 team on call rotation, with ability to drive into workplace for critical events/needs.

Manage customers during problem resolution and operating efficiently under pressure.

Sit at the computer during scheduled work hours with appropriate breaks while maintaining a high level of alertness and attention to detail.

About the team:

As a part of Corporate Network Engineering team, we are responsible for Edge Network which connects 500+ remote offices to the Enterprise core network as well as into AWS cloud. We own the network standards, deployment mechanisms, automation and delivery of large programs, including AWS VPC transit gateway based networks that connect our traditional networks to Native AWS.

The current edge/CPOP of Amazon office network uses hardware based Cisco Firewall Thread Defence (FTD), Cisco ASA and are connected to AWS VPC using AWS Direct Connect and Transit gateways. The current hardware based Edge network has challenges to availability, monitoring, scaling as we grow in terms of the number of offices. We are thinking of building the next generation SDWAN solution or cloud based edge network using AWS technologies such as NAT gateways, ANF, Load balancers and help connect the offices directly using IPSEC or DX site-links.
