Are you excited by the challenge of writing systems software that runs on millions custom networking cards across millions of hosts?\r\nThis 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, what enforces customer security policies, and what 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.\r\nThis 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. When the world's most ambitious AI companies scale on AWS, they're relying on the software we build.\r\nYou’ll write low‑level systems code in C and Rust running on custom hardware in a real‑time embedded environment. You’ll work on network virtualization protocols, packet processing pipelines, and availability mechanisms that must perform correctly at massive scale with sub‑second latency requirements. You’ll solve problems that span hardware, firmware, and software, and see the direct impact of your work on customers running some of the largest and most demanding workloads in the cloud.Key job responsibilitiesLead and mentor junior engineers on impactful and challenging projectsDesign and implement data plane networking software on custom hardware, working across the full software lifecycle from design through deployment and operationsBuild and improve network virtualization systems that deliver VPC connectivity, security policy enforcement, and performance isolation for EC2 customersInvestigate and resolve complex production issues across distributed embedded systems, driving root‑cause analysis and permanent fixesCollaborate with partner teams across hardware, control plane, and ML platforms to deliver end‑to‑end solutionsBasic Qualifications7+ years of non‑internship professional software development experience7+ years of programming with at least one software programming language experience7+ years of leading design or architecture (design patterns, reliability and scaling) of new and existing systems experienceExperience as a mentor, tech lead or leading an engineering teamPreferred Qualifications8+ years of full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations experienceBachelor's degree in computer science or equivalentAmazon is an equal opportunity employer and does not discriminate on the basis of protected veteran status, disability, or other legally protected status.Our inclusive culture empowers Amazonians to deliver the best results for our customers.
