Full job description

DESCRIPTION

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.

About the team
As a team, we are dedicated to making new team members feel welcome and included. We strive to grow each other through task assignments, mentorship, and trainings. As an Amazonian, you’ll work with some of the most talented engineers in our industry. We believe in attracting, developing and retaining talent from diverse backgrounds. We value different perspectives and looking for team players who are working effectively with teams of diverse peers.

BASIC QUALIFICATIONS

Bachelor's degree or equivalent
Experience in development in the last 3 years, or experience in professional, non-internship software development
Experience designing or architecting (design patterns, reliability and scaling) of new and existing systems, or experience debugging, profiling, and implementing best software engineering practices in large-scale systems
Experience that includes strong analytical skills, attention to detail, and effective communication abilities, or experience troubleshooting and debugging technical systems and experience managing full application stacks from the OS up through custom applications
Track record of meaningful contributions to established open source projects
Strong programming skills in at least two of the following: Java, Python, Node.js, Go, Rust
