• Help build and maintain the core infrastructure that serves as the backbone for Smartsheet. Contribute to a robust environment that ensures the foundational reliability, stability, and performance expected by all of our users. • Work closely with the team every day in a real-time development environment. Actively participate as both a driver and a navigator, asking questions, sharing ideas, and contributing directly to the team's collective code ownership. • Dive deep into system internals. With team support, you will contribute to managing and upgrading large-scale database infrastructure, maintaining complex replication topologies, and automating core operations using AWS, Golang, MySQL, Terraform, Temporal, and GitLab-CI. • Use Test-Driven Development (TDD) to ensure our foundational systems are resilient before they ever touch production. Beyond the code, you will be an active participant in our team book clubs and psychologically safe retrospectives to help continuously elevate how we work. • Share responsibility for operational health of our systems as part of a supportive on-call rotation. You'll be ramped in gradually with experienced teammates available to help.

• Design, develop, and maintain the filesystem and container runtime components of Docker's local runtime stack. • Investigate and resolve correctness, performance, and stability issues in the filesystem layer across macOS, Windows, and Linux. • Work on VirtioFS, OverlayFS, and related filesystem technologies to improve performance and reliability for AI agent workloads. • Contribute to containerd integration and OCI-compliant container lifecycle management. • Collaborate with peers on the team to evolve the architecture of the runtime as requirements grow. • Engage with the open source community on filesystem and container runtime related projects. • Participate in on-call rotations and respond to critical stability issues affecting users. • Document your work clearly and share knowledge with the rest of the team.
