Software Engineer, Storage Systems (Agent Infra)
baseten · San Francisco, CA · Posted 10 days ago
Own the storage layer behind thousands of concurrent agent sandboxes, solving FUSE cache coherency and multi-attach correctness on a small team that ships in weeks.
Storage decides how fast agent sandboxes start and how safely they share data. Agents need a filesystem that thousands of sandboxes mount at the same time, with strict isolation and the consistency agents need. Agent context is mostly small files, so the access patterns look very different from storage built for large files.
The Agent Infra team builds Agent Drive, the distributed filesystem that agent sandboxes mount over FUSE, and the storage underneath it. The work uses tiered caching, replication, content-addressed data, and Linux filesystem internals. In September 2026, Baseten acquired Blaxel https://www.baseten.co/blog/blaxel-is-joining-baseten-to-build-the-future-of-agentic-cloud/, whose sandboxes and Agent Drive filesystem are the foundation for Baseten Sandboxes https://docs.baseten.co/sandboxes.
We are building a cloud, not just using one, so storage is designed for many tenants from day one. The team is small and ownership is big: we ship in weeks and months, not multi-year programs.
If you care about page cache coherency, FUSE, replication protocols, and content-addressable storage, we'd love to talk.
