The Runtime team builds and maintains the core container runtime systems that power Docker, including the Moby Engine, containerd, and related low-level components. These systems are the foundation for Docker Desktop and much of the broader container ecosystem.
This team works at the deepest layers of Docker’s technology stack, close to Linux, Go, container runtimes, and system internals. The work directly impacts millions of developers and countless downstream tools.
The team is actively evolving Docker’s runtime architecture, modernizing long-standing components and building the next generation of container isolation, performance, and security capabilities, including virtualization-based approaches for new and emerging workloads.
As a Senior Software Engineer on the Runtime Container Platform team, you will work on the systems that actually make containers run. This role is focused on building and evolving the container runtime itself, not on orchestrating or deploying containers.
You will collaborate with other senior engineers to design, implement, and maintain core runtime functionality, balancing stability for existing users with thoughtful evolution of Docker’s architecture.
This role is ideal for engineers who enjoy working on foundational systems, digging into complex problems, and improving the developer experience by solving issues at the root.
This role is 100% remote, only open to US-based folks.
Design, build, and evolve core container runtime features in Go and Linux environments
Work on foundational systems including Docker Engine, containerd, and related runtime components
Maintain and improve large open source codebases used across Docker products and the broader ecosystem
Collaborate with other Docker teams to integrate runtime capabilities with products like Docker Desktop and Docker Hub
Partner with upstream open source communities and contributors
Make thoughtful tradeoffs between performance, security, reliability, and developer experience
Requirements:
Strong experience building systems in Go or deep experience in another systems language with willingness to work primarily in Go
Solid background working in Linux environments
Hands-on experience with container runtimes or low-level container technologies such as Docker Engine, containerd, or runc
Experience working close to the container stack, including runtime, image building, networking, isolation, or similar areas
Comfort working in large shared codebases and collaborating closely with other engineers
Preferred
Contributions to open source projects, especially CNCF or container-related projects
Experience with virtualization technologies such as Firecracker, QEMU, VirtIO, or microVMs
Knowledge of Linux internals including networking, kernel interfaces, or system performance
Experience building developer tooling, CLIs, or platform infrastructure used by other teams
This role is 100% remote and only open to candidates currently located and authorized to work in the United States.
