## Job description

We're looking for a talented early-career engineer to join our team that owns the network stack for EC2 distributed AI/ML systems. You'll work on software that enables the world's largest AI models to train across massive GPU clusters, developing support for communication libraries and frameworks like NCCL, NVSHMEM, and NIXL.

### Key job responsibilities

- Build and maintain infrastructure that monitors functionality and performance of large-scale AI/ML workloads

- Develop automation using Python and AWS tools (CI/CD, Grafana, Athena) to test, benchmark, and deliver software to customers

- Design mechanisms to detect functional and performance regressions before they reach production

- Work across many instance types, software stacks, and Linux environments
