Manager III, Security Engineer, InfraSec Access Boundary Security

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.

You’ll join a diverse team of software, hardware, and network engineers, supply chain specialists, security experts, operations managers, and other vital roles. You’ll collaborate with people across AWS to help us deliver the highest standards for safety and security while providing seemingly infinite capacity at the lowest possible cost for our customers. And you’ll experience an inclusive culture that welcomes bold ideas and empowers you to own them to completion.

The AWS Infrastructure Security Boundary Protection team is seeking a Security Engineering Manager to lead initiatives that protect AWS's operational network across the full device lifecycle—from provisioning through decommissioning.

In this role, you will manage a team of engineers responsible for network access controls, vulnerability management, and security validation across AWS's global infrastructure. Your team will leverage best-in-class technologies, including:

• AI-powered anomaly detection
• Machine learning for exposure identification
• Configuration validation using automated reasoning
• Observability platforms
• ACL management
• Device fingerprinting
• Security telemetry systems

You will drive the application of artificial intelligence and machine learning to transform how we detect, prevent, and respond to security threats at unprecedented scale. Through leadership of your team, partnerships within Infrastructure Security, and relentless customer obsession, you will raise the bar for network security—driving the vision for securing the largest and most complex network in the world.

AWS leads and innovates. We research and pursue the best approach for the business, whether that means building new solutions or leveraging existing ones. AWS—and Infrastructure Security in particular—operates at massive scale and demands the highest standards, passion, and discipline for information security. The highest level of ownership and accountability is essential for this role.
