Embedded Software Engineer

Description
AWS Utility Computing (UC) provides product innovations — from foundational services such as Amazon's Simple Storage Service (S3) and Amazon Elastic Compute Cloud (EC2), to consistently released new product innovations that continue to set AWS's services and features apart in the industry. As a member of the UC organization, you'll support the development and management of Compute, Database, Storage, Internet of Things (Iot), Platform, and Productivity Apps services in AWS. Within AWS UC, Amazon Dedicated Cloud (ADC) roles engage with AWS customers who require specialized security solutions for their cloud services.

Annapurna Labs, as part of AWS, is seeking an Embedded Software Engineer to architect the networking foundation of tomorrow's cloud. Join the ENA drivers team and build high-performance networking solutions at massive scale—delivering exceptional bandwidth, ultra-low latency, and industry-leading packets-per-second (PPS) performance that powers AWS's global cloud infrastructure.

As an Embedded Software Engineer on the ENA team, you'll develop kernel and user-space drivers that run on millions of instances across Linux, Windows, FreeBSD, and other operating systems. Your work will span cutting-edge AWS proprietary technologies and open-source contributions that benefit the global developer community. You'll play a critical role in AWS operational excellence—monitoring cloud infrastructure health, maintaining world-class quality standards, and enhancing the open-source ENA drivers used by AWS customers worldwide.

Key job responsibilities

• Architect and implement networking drivers for next-generation AWS Nitro controllers serving millions of instances
• Push the boundaries of network performance—optimizing for maximum bandwidth, PPS, and minimal latency across AWS infrastructure
• Own driver development and enhancement across multiple operating systems (Linux, Windows, DPDK, FreeBSD, MacOS, and more)
• Drive software architecture decisions and contribute to upstream open-source repositories that shape the future of cloud networking
• Partner with internal teams and external customers to solve complex, high-impact technical challenges
• Ensure cloud reliability by monitoring infrastructure health and upholding exceptional quality standards
