Description

AWS Infrastructure Services owns the design, planning, delivery, and operation of all AWS global infrastructure. In other words, we’re the people who keep the cloud running. We support all AWS data centers and all of the servers, storage, networking, power, and cooling equipment that ensure our customers have continual access to the innovation they rely on. We work on the most challenging problems, with thousands of variables impacting the supply chain — and we’re looking for talented people who want to help.

You’ll join a diverse team of software, hardware, and network engineers, supply chain specialists, security experts, operations managers, and other vital roles. You’ll collaborate with people across AWS to help us deliver the highest standards for safety and security while providing seemingly infinite capacity at the lowest possible cost for our customers. And you’ll experience an inclusive culture that welcomes bold ideas and empowers you to own them to completion.

Do you want to design, build and operate services that are used by millions of customers every day? Are you passionate about architecting highly available and large-scale services?

If the answer is yes, the Elastic Load Balancing (ELB) team wants to talk with you. ELB is a disruptive service that offers customers incredibly scalable and robust load balancing technology. We are building new services to launch in the next year and we plan to continue to grow the team.

Why you should join the Amazon ELB team?

We are building and launching new services and features on a regular basis. Application load balancer(ALB), Network load balancer(NLB), Gateway load balancer (GWLB) and Privatelink are a few examples.

We ship software frequently, get fast feedback from real customers around the globe, and see the results of our work come to fruition. The Amazon ELB service is deployed globally to 30+ regions today and is growing at an extremely rapid rate.

There are real-world problems to solve that you won’t find ready-made answers for. For example, how do you ensure customers can scale their application quickly to handle traffic spikes and then back down in a matter of minutes? How do you design a load balancing solution that allows customers to quickly and easily achieve the highest levels of fault tolerance using Amazon EC2?

We are now designing and building the next generation of ELB services capable of handling terabytes of data per day and growing from there. This is a unique opportunity to help build large-scale systems from the ground up.

If this sounds great and you are up to the challenge, we’d love to hear from you. Amazon Web Services is changing the world, and this is a great opportunity to be a part of this exciting business.
