Job summary
EC2 Nitro drives the planet's largest, fastest growing and most feature-rich compute cloud. Nitro is AWS's 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 - Graviton2 - while raising the industry bar for security and performance across our product line. The Nitro Team is looking for engineers with systems knowledge and experience in area such as Linux OS boot sequencing, Kernel, Hypervisor (Xen or KVM), peripheral device development (PCIe or NVMe) and low-level PC systems such as BIOS.

The Nitro Instance Services team is a critical middle layer that is the cornerstone of the Nitro design. It provides legacy device emulation, DNS and Instance Meta-data Service (IMDS) to the guest instance. It interfaces directly with system BIOS for bare-metal instances and drives critical system interactions within the Nitro Hypervisor and across EC2 control-plane services. We need engineers with the dive-deep and ownership to work across domains (such as PC peripheral firmware or Linux Kernel internals) to deliver features and new instance types for our customers. Work is typically done in C/C++ or Rust with supporting script and tests in Python and Lua. Senior Software Development Engineers work closely with EC2 Principal Engineers and other technical leaders to define technical direction, and then follow through with detailed analysis, designs, and high quality code.

Our team is diverse! We drive towards an inclusive culture and work environment. We are intentional about attracting, developing, and retaining amazing talent from diverse backgrounds. Team members are active in Amazon's 10+ affinity groups, sometimes known as employee resource groups, which bring employees together across businesses and locations around the world. These range from groups such as the Black Employee Network, Latinos at Amazon, Indigenous at Amazon, Families at Amazon, Amazon Women and Engineering, LGBTQ+, Warriors at Amazon (Military), Amazon People With Disabilities, and more.

We value work-life balance and believe striking the right balance between your personal and professional life is critical to life-long happiness and fulfillment. We offer flexibility in working hours and encourage you to find your own balance between your work and personal lives.

Our team is dedicated to supporting new members. We have a broad mix of experience levels and tenures, and we're building an environment that celebrates knowledge sharing and mentorship. Our senior members enjoy one-on-one mentoring and thorough, but kind, code reviews. We care about your career growth and strive to assign projects based on what will help each team member develop into a better-rounded engineer and enable them to take on more complex tasks in the future.

This team creates the very core of the cloud, and is directly responsible for radically changing and improving the way that people use computers - come help us make history!
