Systems Development Engineer II, ADC Security Services (A2SE)

Application deadline: Aug 4, 2026

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
