Software Development Engineer - Lambda, AWS Lambda Control Plane

Software Development Engineer — AWS Lambda Control Plane (Dublin) When millions of builders ship their Lambda functions, it all just works — in seconds, anywhere in the world. The machinery that makes that possible is the control plane: the systems that validate, orchestrate, and propagate every function's state so the data plane can execute it flawlessly at any scale. As part of the team you'll design, build, and operate the distributed systems that sit between customers and the Lambda data plane: You'll own the full path from API request to running function. The APIs you build are the public surface of Lambda — high-throughput, strictly consistent, globally available — serving customers and CloudFormation alike. Behind those APIs, you'll design the asynchronous workflows that orchestrate a function's lifecycle: taking a customer's intent — a new function, a code deploy, a version publish — and propagating it safely to the systems that actually execute functions. That means solving metadata propagation at global scale: ensuring every configuration change reaches the right compute fleet, in the right region, with the right ordering guarantees, even under partial failures. We operate at the scale of one of the largest services in AWS. Availability is a first-class design constraint, not an afterthought. What we're looking for - Experience designing and operating distributed systems in production — the kind where "retry" isn't a strategy, it's a starting point. - Comfort with ambiguity: you'll own problems end-to-end, from API contract through data-plane handoff. - Strong fundamentals in at least one of: Java, Python, or TypeScript (our stack spans all three). - A bias toward simple, operable solutions — systems that are easy to reason about at 3 AM. About the team We're a Dublin-based engineering team within AWS Lambda. We invest in growing engineers through meaningful ownership, direct mentorship, and exposure to problems that don't have textbook answers. We value diverse perspectives and hire for collaboration — the best systems here are built by teams, not individuals. - Experience (non-internship) in professional software development - Experience designing or architecting (design patterns, reliability and scaling) of new and existing systems - Experience programming with at least one software programming language - Bachelor's degree in computer science or equivalent - Experience with full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations Amazon is an equal opportunities employer.
