Working for Annapurna Labs is thrilling, fast-paced, and a constant learning experience. The AWS Graviton SW team is looking for an 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 bring-ups, 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 bring-up 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
