Systems Development Engineer II, ADC Security Services (A2SE)

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 resolve production software issues across multiple

languages (Python, Java, TypeScript, Bash, Ruby) on Linux-based systems

- Develop tools, automation, and monitoring solutions to reduce manual toil and

improve operational excellence, leveraging AI/ML capabilities and large language

models where appropriate

- Conduct deep-dive troubleshooting and technical post-mortems to identify root

causes of complex issues spanning distributed systems

- Proactively address system variances affecting major services, investigating

service inter-dependencies and region-specific configurations across Linux

environments

- 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 that improve the builder experience, including AI-assisted

development workflows

- Apply strong Linux systems administration skills (networking, process

management, filesystems, security hardening) to support operational and

development work

- Leverage generative AI tools and prompt engineering techniques to accelerate

development, automate repetitive tasks, and enhance code quality

- Mentor other engineers and contribute to a culture of knowledge-sharing and

technical excellence

About the team

Why AWS

Amazon Web Services (AWS) is the world’s most comprehensive and broadly adopted

cloud platform. We pioneered cloud computing and never stopped innovating —

that’s why customers from the most successful startups to Global 500 companies

AWS Infrastructure Services (AIS)

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.

Inclusive Team Culture

Here at AWS, it’s in our nature to learn and be curious. Our employee-led

affinity groups foster a culture of inclusion that empower us to be proud of our

to never stop embracing our uniqueness.

Work/Life Balance

We value work-life harmony. Achieving success at work should never come at the

expense of sacrifices at home, which is why we strive for flexibility as part of

our working culture. When we feel supported in the workplace and at home,

there’s nothing we can’t achieve in the cloud.
