Job summary

Baseten is hiring for a storage-focused role where you will design and implement Agent Drive, a distributed filesystem powering sandboxes and tenants. You will tackle metadata replication, volume placement, and FUSE client behavior, while addressing cache coherency, crash consistency, and tail latency in a fast-moving, small team.

You will work on tiered caching, content-addressed data, and Linux filesystem internals, contributing to upstream OSS.

Qualifications

• Strong systems programming background in Go, Rust, and/or C/C++, with comfort reading kernel code.
• Deep understanding of Linux filesystem and storage internals: VFS, page cache, dentry and inode caches, FUSE, the block I/O stack, fsync semantics, and crash consistency.
• Hands-on experience building distributed storage systems, content-addressable storage, or large-scale caching infrastructure.
• Experience profiling I/O, memory, and RPC bottlenecks and optimizing tail latency in production.
• Ability to debug correctness bugs that only show up under concurrency or partial failure.
• You move fast and like owning a problem end to end on a small team.

Responsibilities

• Design and implement core Agent Drive features: metadata replication, volume placement, garbage collection, and FUSE client behavior.
• Solve multi-attach correctness: cache coherency across many FUSE mounts of the same drive, dentry and inode invalidation, write ordering, and crash consistency.
• Optimize tail latency on read and write paths, including page cache strategy, writeback, prefetch, and metadata RPC batching.
• Build tenant isolation into the storage layer, including quota enforcement, blast-radius containment, and noisy-neighbor mitigation.
• Own the storage side of sandbox startup and resume performance.
• Build durable block storage for sandboxes alongside other Baseten storage teams.
• Build observability into every layer, drive storage incidents end to end, and turn each one into a permanent fix.
• Contribute upstream to the open-source storage projects we build on.
