Nitro is a hardware/firmware/software solution built from the ground-up to support secure virtualization at AWS scale. The Nitro Build Team owns the systems and tooling that manage low-level system firmware integration, performance, instrumentation and validation. Every single cloud instance at EC2 is built on top of the work done by this team - everything from Machine Learning oriented GPU instances, to Storage, and HPC instances. These are used to power critical workloads from startups to the Fortune 500.

If you have a passion for systems software design and engineering, then this is an opportunity to build the core of the AWS cloud. A SysDE on Nitro Build Team will work closely with Principal Engineers from HW Engineering, Firmware and EC2 data-plane and services teams to ensure low-level firmware (such as system BIOS or TPM firmware) integrates robustly with the Nitro stack. A SysDE will use C, Lua or Python, conduct software design reviews, code reviews, automated test development, deployment, and fleet monitoring.

On the Nitro Build Team we value Customer Obsession and look for engineers who understand the challenges and responsibility of supporting foundational technologies within the Nitro Stack and across the world's premiere cloud virtualization infrastructure. We're looking for engineers who show Ownership and take pride in supporting major EC2 Customers from across the tech landscape.

Here at AWS, we embrace our differences. We are committed to furthering our culture of inclusion. We have ten employee-led affinity groups, reaching 40,000 employees in over 190 chapters globally. We have innovative benefit offerings, and host annual and ongoing learning experiences, including our Conversations on Race and Ethnicity (CORE) and AmazeCon (gender diversity) conferences. Amazon's culture of inclusion is reinforced within our 14 Leadership Principles, which remind team members to seek diverse perspectives, learn and be curious, and earn trust.

Our team puts a high value on work-life balance. It isn't about how many hours you spend at home or at work; it's about the flow you establish that brings energy to both parts of your life. We 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.
