Saved job 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.

Amazon is seeking an experienced, results-oriented, Senior Software Dev Engineer.

What do we do here? Amazon Web Services (AWS) runs one of the largest networks in the world. We are putting services and algorithms in place to control the traffic flow across the different fabrics of the Amazon network, taking static topological information as well as real-time network inputs into account.

Why do we do that? In Amazon, we are always customer obsessed. By responding fast to network changes like scaling, maintenance, failure, security and other types of events, we lower the cost and overhead for customers, while driving up performance, availability and reliability.

Why now? As we expand the reach of our algorithms and services, we need to scale and are looking for a talented software development engineer that wants to get experience with Software Defined Networking (SDN), hyper scale data center networks, cloud infrastructure, large-scale software deployments, algorithms and SOA.

How do we operate? We empower people to take ownership of their realm and make a difference. We work backwards from customer needs, gather requirements, diving deep to choose technologies, designing features and spinning new services, deploying software across the globe and maintaining services. In AWS, we are nimble and agile, like being part of a startup, innovating while collaborating with smart group of people around you. We are thrilled about software and we are changing the landscape of networking. We operate on an unimaginable scale. We push the boundaries in robustness, fault-tolerance and smart adaptive algorithms that can react intelligently to real-world events.

Key job responsibilities

- Owning multiple services and features, architecting them to scale with robust unit tests and metrics

- Understanding customer needs by working with external and internal stakeholders and translating it to software requirements and execution plans

- Leading team members to manage the day-to-day development activities, participate in designs, design review, code review, and implementation.

- Mentoring and leading junior engineers and guiding them towards good software development techniques

- Maintaining current technical knowledge to support rapidly changing technology, always on a look out for new technologies and work with the team in bringing in new technologies.

A day in the life

You will architect, design, implement, test, and deploy new features to improve scale and availability of the network

You will look for continuous improvement to reduce the cost of operating the network

You will exercise the highest bar for security in both code and operations.

You will find new ways to provider deeper insight on the health of our service and meet customer expectations on availability.

About the team

We are a highly motivated team of software, system and network developers who thrive on solving challenging problems and building large-scale distributed software systems.
