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.

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
