EC2 Core Compute drives the planet’s largest, fastest growing and most feature-rich compute cloud. Nitro is AWS’ ground-up design for virtualization at global scale built on a fully custom stack of hardware, firmware and applications. Nitro has enabled EC2 to support Intel, AMD and Amazon’s custom silicon - the Graviton processor family - while raising the industry bar for security and performance across our product line. We integrate hardware, firmware, application software and services to deliver new virtualized and bare-metal compute platforms for companies from startups through the Fortune 500.

As a skilled engineer with expertise in C, you'll work on software that provide essential services to customer instances and EC2 dataplane applications. This role offers unique opportunities to design and build high-performance, reliable services that operate at massive scale to ensure customers are able to launch instances successfully while simultaneously protecting EC2 resources from potential security threats.

This position requires an engineer who thrives in an embedded systems environment and can deliver robust solutions for the infrastructure that underpins AWS services. You'll help shape the future of cloud computing by creating efficient, scalable, and secure services that operate close to the hardware. Your contributions will directly impact customer experience and the performance of one of the world's largest cloud platforms.
