Embedded Software Engineer, Graviton

Job description

Working for Annapurna Labs is thrilling, fast-paced, and a constant learning experience. The AWS Graviton SW team is looking for a Senior Embedded Engineer to join us in building next-generation platforms. In this role, you will develop firmware and low-level software for our custom silicon, participate in board and chip bringups, and help bring Graviton devices into the AWS fleet at scale. If you're passionate about working at the intersection of hardware and software — from first silicon power-on to production deployment — this is the role for you.

Key job responsibilities

- Develop and maintain embedded firmware (C/C++) for Graviton platform components, including host MCU and related subsystems

- Participate in board and chip bringup activities — from early silicon validation through production readiness

- Develop and maintain boot loaders, drivers, and RTOS-based firmware for multi-core ARM devices

- Collaborate with hardware engineers to validate new board designs, reading schematics and using lab tools (oscilloscopes, logic analyzers) for hands-on debugging

- Develop firmware flows and commands used during fleet testing, monitoring, and operational events (e.g., Gamedays)

- Contribute to the full lifecycle of platform development — from prototype to high-volume production in the AWS fleet

- Work cross-functionally with silicon, platform, and fleet health teams to ensure reliability and performance at scale

A day in the life

You'll be debugging a new chip's first boot sequence in the lab, writing firmware for hardware monitoring, or collaborating with hardware engineers on next-generation platform designs. You'll work across Annapurna Labs teams - from silicon design to fleet operations - ensuring our Graviton platforms are robust and ready for the world's largest cloud.

About the team

At the platforms team, you'll be working on large and complicated boards, bringing our Silicon devices into the AWS fleet. You'll have the opportunity to shape our next gen platforms and work on the technologies that power the world's largest Cloud provider.
