SDE II, EC2 Instance Networking

Do you want to build the networking infrastructure that powers every virtual machine in the world's largest cloud? Are you excited by the challenge of writing systems software that runs on millions of custom networking cards across millions of hosts? The Amazon Elastic Compute Cloud (EC2) Instance Networking team builds and operates the software-defined networking stack at the heart of AWS.

Our code is what makes Virtual Private Clouds (VPC) work, enforces customer security policies, and enables workloads to scale from a single instance to clusters of tens of thousands. Every packet that enters or leaves an EC2 instance flows through software we write, running on custom silicon designed in-house. This work sits at the intersection of cloud infrastructure and the AI revolution.

As machine learning workloads grow to unprecedented scale - training runs spanning thousands of accelerators, clusters demanding millions of network endpoints, and fabrics pushing hundreds of gigabits per second - we build the networking primitives that make these workloads possible: high-performance interfaces, low-latency data plane protocols, and scalable network virtualization that operates predictably even under heavy churn.

• Design and implement data plane networking software on custom hardware, working across the full software lifecycle from design through deployment and operations.
• Build and improve network virtualization systems that deliver VPC connectivity, security policy enforcement, and performance isolation for EC2 customers.
• Investigate and resolve complex production issues across distributed embedded systems, driving root cause analysis and permanent fixes.
• Collaborate with partner teams across hardware, control plane, and ML platforms to deliver end-to-end solutions.

• 3+ years of non-internship professional software development experience.
• 2+ years of non-internship design or architecture experience of new and existing systems.
• 1+ years of software development engineer or related occupational experience.
• 1+ year of designing and developing large-scale, multi-tiered, multi-threaded, embedded or distributed software applications, tools, systems, and services, using languages such as C#, C++, Java, or Perl.
• Bachelor's degree or foreign equivalent in Computer Science, Engineering, Mathematics, or a related field.
• Experience programming with at least one software programming language.

• 4+ years of full software development life cycle experience, including coding standards, code reviews, source control management, build processes, testing, and operations.
• Knowledge of system performance, memory management, and parallel computing principles.
• Experience in networking, large-scale distributed systems, or a related field.
• Experience with Linux and networking protocols.
