Job description

Senior SW Engineer, Network Drivers, ENA

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 new product features that set AWS apart in the industry. As part 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 customers requiring specialized security solutions for their cloud services.

Working for Annapurna Labs is dynamic and fast-paced. As an ENA Drivers SW development engineer, you will develop kernel-space and user-space network drivers for customer virtual machines. You will create features for Annapurna Labs' next-generation hardware to enable high network bandwidth and packets-per-second (PPS) performance with low latency. Your role involves shaping software designs, staying updated with OS features, resolving complex customer issues, and maintaining high-quality, optimized code to ensure exceptional customer satisfaction.

Annapurna Labs, part of AWS, develops innovative hardware and software for cloud customers. We are like a startup within AWS, working on cutting-edge technologies with talented engineers. Our products, such as Elastic Network Adapter (ENA), are central to AWS cloud networking infrastructure and are used by millions of customers.

ENA drivers support multiple operating systems (Linux, Windows, DPDK, FreeBSD, MacOS, etc.) and are open-source, available in Amazon's GitHub repositories and OS-specific repositories. These drivers manage the interface between the Nitro controller and virtual instances, handle resources and configurations, and implement advanced networking features. As a SW engineer in the ENA Drivers team, you will design, develop, and upstream new features, collaborate with customers, and maintain high operational standards.
