Security Engineer, Infrastructure Application Security

AWS Security protects the cloud computing environment that millions of customers rely on every day. Our infrastructure security team works directly with the engineers who design, build, and operate AWS data center and infrastructure services, helping them ship securely from the start.

We're looking for a Security Engineer to join our team and provide hands-on security engineering support to infrastructure builders across AWS. You will review architectures, identify security risks, guide teams toward secure designs, and help build tooling that scales security across a broad portfolio of services. You'll work across a range of technologies: networking, hardware lifecycle systems, procurement systems, data center automation, and cloud infrastructure services.

This is a role where you'll grow fast. You will work alongside experienced security engineers who will help you develop depth in threat modeling, secure design review, and security automation. You'll gain exposure to systems operating at massive scale, and you'll build the judgment to prioritize what matters most when everything looks urgent.

We're looking for someone who communicates clearly, asks good questions, digs into problems with persistence, and brings genuine curiosity about how systems fail.

Key job responsibilities
As a Security Engineer supporting infrastructure teams, you will:
- Conduct security design reviews and threat modeling for infrastructure services, identifying risks and providing clear remediation guidance to partner teams
- Perform manual and automated secure code review across infrastructure codebases
- Provide security architecture and design guidance to builders at the ideation and implementation stages
- Develop and maintain security automation tools that scale review processes across the infrastructure portfolio
- Document findings, track remediation progress, and verify fixes with partner teams
- Deliver security training and outreach to internal infrastructure development teams
- Identify and escalate high-severity security issues through appropriate channels, aligned to launch timelines

A day in the life
You'll collaborate with infrastructure engineering teams to help them build secure services from the start. On any given day, you might be threat modeling a new architecture, reviewing code for security issues, building automation to scale security practices, or guiding a partner team through a secure design decision. Senior engineers on your team will help you develop depth in application security and sharpen your ability to communicate risk clearly. Over time, you'll own relationships with partner teams and become their trusted security resource.
