Job summary

Baseten is an AI inference platform building Agent Drive, a distributed filesystem that enables agent sandboxes to mount over FUSE, focusing on storage architecture, performance, and multi-tenant isolation.

This role designes and implements core storage features, tackles tail latency, and drives correctness under concurrency while contributing to open-source storage projects and advancing performance across the stack.

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, block I/O, 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 appearing under concurrency or partial failure conditions.

Responsibilities

• Design and implement core Agent Drive features including metadata replication, volume placement, garbage collection, and FUSE client behavior.
• Solve multi-attach correctness problems: cache coherency across many FUSE mounts, 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 with quota enforcement, blast-radius containment, and noisy-neighbor mitigation.
• Own storage-side sandbox startup and resume performance, build observability into every layer, and contribute upstream to open-source storage projects.
