Job description

Software Development Engineer, Lambda - Experience

Job ID: 10436932 | Amazon Development Centre Ireland Limited

AWS Lambda is a serverless compute service that lets customers run code without provisioning or managing servers. As part of the AWS Lambda team in Dublin, you'll work on one of the fastest-growing services in AWS, processing trillions of invocations monthly for millions of customers worldwide.

We're seeking an experienced Software Developer to join our Dublin-based team working on AWS Lambda's Runtimes. The Runtimes team holds a unique position within Lambda, owning implementation, documentation, security updates, and supporting libraries that define how developers write and run code across multiple languages in Lambda. Unlike teams owning discrete services, Runtimes owns software with an extraordinarily large surface area spanning runtime versions across seven languages (Python, NodeJS, Java, .NET, Ruby, Go, Rust), each with its own dependencies, behaviors, and integration patterns with the Lambda platform and broader serverless ecosystem. This is a customer-visible and developer-scrutinized area in Lambda.

An SDE in this domain must possess versatile expertise across multiple programming languages and a nuanced understanding of how customers experience Lambda through its programming models. They actively engage with upstream open-source communities, ensuring Runtimes align with evolving language advancements. They simplify Runtime operations for efficiency and scalability, balancing security patching urgency against customer disruption risk.

This role offers the opportunity to solve complex challenges at scale and deliver best in class serverless customer experience.
