Software Development Engineer - EC2 Networking

Amazon Dev Center U.S., Inc. Arlington, VA

About the Job

Imagine being part of a team working on fundamental building blocks of all customers of EC2. We are excited to have you help us build the next generation of features for managing IP space and connecting to EC2 Instances on the Amazon Web Services (AWS) EC2 Networking, IP Management & Instance Connectivity team in Northern Virginia!

We build software core to the EC2 network virtualization systems supporting the massive AWS cloud. Our area of influence continues to grow as our engineers grow. Currently, we are tackling new features in IP Management (how AWS manages its IPv4 and IPv6 space) and Connectivity (how customers connect and communicate with their EC2 instances), with goals of improving the overall health and safety of the entire internet.

On any given day we may use Kotlin, Java, DynamoDB, AWS Lambda, ECS, S3, SQS, SNS, CloudFormation, and a set of internal automation tools. We choose the right tool for the job, so this list often varies slightly as we tackle each customer problem. Engineers are not expected to have prior experience in these technologies, but they are expected to be excited to learn about them.

Job responsibilities

You use technology to solve straightforward problems, seeking input and guidance from team members. You may create or have responsibility to improve or invent small tools or applications. You are able to take a defined design and turn it into code and deliver it on schedule, applying appropriate technologies and current software engineering best practices. You write secure, stable, testable, maintainable code with minimal defects. You are proficient in a broad range of data structures and algorithms, knowing when it is appropriate to use them (and when it is not). You make appropriate implementation trade-off decisions (e.g., array or hash table). You do not put the company at risk (e.g. pulling in unlicensed code, working on code in unsafe ways, etc.). You participate in team design, scoping and prioritization discussions. You seek to learn the business context and technologies behind your team’s software. You work effectively with customers and/or internal partners to understand business impacts and identify any opportunities/problems arising from technical decisions. You invent, refine and develop your solutions to ensure they are meeting customer needs and team goals. You are a passionate advocate for your customer.

You assume responsibility for the state of the code you both inherit and produce. You get your designs and code reviewed. You test your code thoroughly. You classify, store, and handle data in accordance with Amazon policies. You track security risks and mitigate and/or escalate them in a timely manner. You understand the maintenance characteristics, runtime properties, and dependencies of your team’s software, including hardware platform, operating system and build dependencies. You clearly document your software to ensure that future generations of developers understand the intention behind the features and components you build. You may be part of an oncall rotation. In the event of a problem, you are able to troubleshoot, research the root cause of problems, and thoroughly resolve defects. You provide excellent customer support. You take ownership of problems (even when outside your own domain), propose solutions, and either take ownership for their resolution or ensure a clear hand-off to the right owner. You participate in the interview process and help your team train SDE interns.
