Company

Baseten builds infrastructure, developer tooling, and production inference platforms for AI companies, including distributed storage and sandbox infrastructure for agentic applications.

What you will do

• Design and implement Agent Drive features, including metadata replication, volume placement, garbage collection, and FUSE client behavior.
• Solve multi-attach correctness across FUSE mounts through cache coherency, dentry and inode invalidation, write ordering, and crash consistency.
• Optimize read and write tail latency through page-cache strategy, writeback, prefetch, and metadata RPC batching.
• Build tenant isolation, quota enforcement, blast-radius containment, and noisy-neighbor mitigation into the storage layer.
• Own storage-related sandbox startup and resume performance, build durable block storage, and contribute to upstream open-source storage projects.
• Build observability into each storage layer, lead storage incidents end to end, and turn incidents into permanent fixes.

Requirements

• Strong systems programming background in Go, Rust, and/or C/C++, with comfort reading kernel code.
• Deep understanding of Linux filesystem and storage internals, including 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-addressed storage, or large-scale caching infrastructure.
• Experience profiling I/O, memory, and RPC bottlenecks and optimizing production tail latency.
• Ability to debug correctness bugs that occur under concurrency or partial failure.
• Ability to move quickly and own problems end to end on a small team.

Nice to have

• Experience with distributed filesystems or object stores such as JuiceFS, CephFS, or S3-compatible storage, or contributions to those projects.
• Knowledge of consensus and replication protocols such as Raft, leader leases, and quorum reads.
• Experience with snapshot, clone, and copy-on-write filesystem features.
• Experience operating multi-tenant storage with hard isolation requirements.
• Familiarity with Linux performance tools such as eBPF, io_uring, perf, ftrace, and blktrace.

Culture & Benefits

• Meaningful equity and competitive compensation.
• Medical, dental, and vision insurance fully covered for employees and dependents in the United States.
• Flexible PTO and a company-wide Winter Break from Christmas Eve through New Year's Day.
• Paid parental leave and a fertility and family-building stipend through Carrot.
• Company-facilitated 401(k) in the United States.
• Exposure to ML startups and opportunities for learning and networking.
