Responsibilities
- 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 into the storage layer with quota enforcement, blast-radius containment, and noisy-neighbor mitigation.
- Own storage-related sandbox startup and resume performance.
- Build durable block storage for sandboxes with other storage teams.
- Add observability across storage layers, lead storage incident resolution, and implement permanent fixes.
- Contribute upstream to the open-source storage projects used by the team.
Requirements
- Strong systems programming experience 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, block I/O, 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 issues under concurrency or partial failure.
- Ability to move quickly and own problems end to end on a small team.
- Preferred experience with distributed filesystems or object stores such as JuiceFS, CephFS, or S3-compatible storage.
- Preferred knowledge of consensus and replication protocols such as Raft, leader leases, and quorum reads.
- Preferred experience with snapshot, clone, and copy-on-write filesystem features.
- Preferred experience operating multi-tenant storage with hard isolation requirements.
- Preferred familiarity with Linux performance tools including eBPF, io_uring, perf, ftrace, and blktrace.
Benefits
- Competitive compensation including meaningful equity.
- U.S. employees and dependents receive 100% coverage of medical, dental, and vision insurance.
- Flexible PTO and a company-wide Winter Break from Christmas Eve through New Year's Day.
