As a Nitro Operating Systems engineer, your day centers around developing and optimizing the specialized OS that powers AWS's Nitro system. You might start by reviewing telemetry data from overnight kernel performance tests, then dive into coding a new virtualization feature for an upcoming EC2 instance type. After lunch, you'll debug a thorny memory allocation issue that's causing sporadic system hangs. Later, you'll collaborate with hardware engineers to optimize driver code for new Nitro hardware. You'll wrap up by documenting your kernel modifications and preparing for tomorrow's design review with fellow OS engineers. Throughout the day, you'll balance planned feature development with quick investigations of any critical system issues that arise.
