Software Development Engineer, Bottlerocket

As a Software Development Engineer on the Bottlerocket team, you will design, build, and maintain components of Bottlerocket - AWS"s open-source, security-first container OS trusted by thousands of customers to run production workloads at massive scale.

As an SDE2, you"ll write Rust and Go in the open on GitHub, shipping systems software that runs on millions of hosts worldwide - spanning OS services, container runtime integrations, update mechanisms, and orchestrator support for EKS and ECS. You"ll solve hard problems in Linux internals, security hardening, and performance at unprecedented container density, while building the CI/CD and release tooling that powers safe, rapid OS delivery.

This is a uniquely open team within AWS: real open-source, real community, and real low-level engineering on infrastructure customers trust to run their most important workloads.
