Software Engineer for Storage Systems

Skills

About the Role

You will design and implement distributed storage features for sandbox workloads. You will solve FUSE consistency and multi-attach correctness, optimize I/O latency, enforce tenant isolation, improve startup performance, and investigate storage incidents through lasting fixes.

Requirements

• Systems programming experience with Go, Rust, or C/C++
• Knowledge of Linux filesystem and storage internals, including VFS, page cache, FUSE, block I/O, fsync, and crash consistency
• Experience building distributed storage, content-addressable storage, or large-scale caching
• Experience profiling I/O, memory, and RPC bottlenecks and optimizing tail latency
• Ability to debug concurrent and partial-failure correctness issues

Responsibilities

• Design and implement metadata replication, volume placement, garbage collection, and FUSE client features
• Solve cache coherency, invalidation, write ordering, and crash consistency across FUSE mounts
• Optimize read and write tail latency through caching, writeback, prefetch, and RPC batching
• Build storage-layer tenant isolation, quotas, containment, and noisy-neighbor mitigation
• Own storage contributions to sandbox startup and resume performance
• Build durable block storage for sandboxes
• Build observability, lead storage incident resolution, and implement permanent fixes
• Contribute to relevant open-source storage projects

Benefits

• Meaningful equity
• Medical, dental, and vision insurance for U.S. employees and dependents
• Flexible PTO and company-wide winter break
• Paid parental leave
