Description

AWS Lambda MicroVMs is at the forefront of the next evolution in serverless computing. Launched to enable developers to run isolated sandboxes with full lifecycle control, Lambda MicroVMs are powered by Firecracker, the same lightweight virtualization technology behind over 15 trillion monthly Lambda function invocations. The service is rapidly growing as the default platform for executing untrusted and AI-generated code in hardware-isolated environments with sub-second launch and resume capabilities.

We are seeking Software Development Engineers interested in driving the evolution of the Lambda MicroVMs platform. Our teams build and operate the end-to-end systems behind Lambda MicroVMs, from the ingress layer that securely routes customer traffic to MicroVM backends, to the orchestration services that launch, suspend, resume, clone, and terminate millions of MicroVMs weekly, to the metering systems that track usage for accurate billing at scale. Together, these systems deliver the serverless experience customers expect: built-in availability, automatic scaling, and zero infrastructure management.

In this role, you will work on developing features that empower customers to run per-user and per-session isolated environments without managing clusters or idle capacity. You will build systems that enable use cases such as sandboxed execution for AI agents, interactive development environments, multi-tenant SaaS isolation, and secure code execution, all with the operational simplicity of serverless. There is a tremendous opportunity to innovate at the intersection of virtualization, serverless, and AI. You will work with languages such as Java, TypeScript, Python, and Rust. Come challenge yourself in our team-oriented atmosphere, and watch yourself grow with one of the most innovative and fastest-growing areas in AWS.
