Are you passionate about security and building systems that protect critical infrastructure at scale? Do you want to join a team that invents, scales, and operates foundational security services used across all of Amazon?

The Amazon Dedicated Cloud (ADC) Security Systems Engineering (AS2E) team is responsible for building, deploying, and maintaining the security services that secure our systems, processes, and data in US Amazon Dedicated Cloud (ADC) Regions. We build authentication, authorization, and enforcement services used across diverse internal teams as they deliver services for our customers. We support all of Amazon.com and AWS with our services, and need solution-oriented thinkers who are passionate about solving problems at scale, thinking through edge cases, and iterating quickly to delight our customers.

You"ll love this team if you are curious about how we design security into the cloud and Amazon infrastructure - from the minute a server hits our data center through how we securely administer and operate services. We are looking for engineers who think deeply about problems, are creative, and think outside the box in ways that benefit our customers. We are a team of out-of-the-box thinkers who iterate quickly and build secure systems that are easy to use.

This position requires that the candidate selected must currently possess and maintain an active TS/SCI security clearance with polygraph. The position further requires the candidate to opt into a commensurate clearance for each government agency for which they perform AWS work.

Key job responsibilities

  • Design, develop, and deploy scalable security solutions across thousands of devices in ADC regions, continuously improving processes to handle massive-scale operations
  • Troubleshoot, diagnose, and fix production software issues across multiple languages (Python, Java, TypeScript, Bash, Ruby)
  • Develop tools, automation, and monitoring solutions to reduce manual toil and improve operational excellence
  • Conduct deep-dive troubleshooting and technical post-mortems to identify root causes of complex issues
  • Proactively address system variances affecting major services, investigating service inter-dependencies and region-specific configurations
  • Collaborate with cross-functional teams to optimize cloud infrastructure maintenance and drive positive customer experiences
  • Design new systems, review code, perform design reviews, and contribute to org-wide initiatives to improve the builder experience
  • Mentor other engineers and contribute to a culture of knowledge-sharing and technical excellence

A day in the life

As a System Development Engineer II, you will collaborate with internal service teams to enhance system health, maintainability, and operational efficiency. Your work will involve improving tooling and product builds, ensuring that our systems run smoothly and effectively. You will tackle complex technical challenges faced by our customers, providing scalable solutions to advanced problems.

The primary focus of the team is on the growth and delivery of Security Services in ADC regions. Working in a high-trust environment, you will partner closely with internal service teams to quickly resolve issues through code, driving positive customer experiences. You will work as part of a team ensuring no one is on an island, and you will be empowered to learn new skills and build new products where you see a need for our customers.

About the Company

A

Amazon.com Inc

At Amazon, we don’t wait for the next big idea to present itself. We envision the shape of impossible things and then we boldly make them reality. So far, this mindset has helped us achieve some incredible things. Let’s build new systems, challenge the status quo, and design the world we want to live in. We believe the work you do here will be the best work of your life.

Wherever you are in your career exploration, Amazon likely has an opportunity for you. Our research scientists and engineers shape the future of natural language understanding with Alexa. Fulfillment center associates around the globe send customer orders from our warehouses to doorsteps. Product managers set feature requirements, strategy, and marketing messages for brand new customer experiences. And as we grow, we’ll add jobs that haven’t been invented yet.

It’s Always Day 1
At Amazon, it’s always “Day 1.” Now, what does this mean and why does it matter? It means that our approach remains the same as it was on Amazon’s very first day – to make smart, fast decisions, stay nimble, invent, and stay focused on delighting our customers. In our 2016 shareholder letter, Amazon CEO Jeff Bezos shared his thoughts on how to keep up a Day 1 company mindset. “Staying in Day 1 requires you to experiment patiently, accept failures, plant seeds, protect saplings, and double down when you see customer delight,” he wrote. “A customer-obsessed culture best creates the conditions where all of that can happen.” You can read the full letter here

Our Leadership Principles
Our Leadership Principles help us keep a Day 1 mentality. They aren’t just a pretty inspirational wall hanging. Amazonians use them, every day, whether they’re discussing ideas for new projects, deciding on the best solution for a customer’s problem, or interviewing candidates.
