Software Engineer — Storage

Anza is the core engineering team behind Solana, developing Agave — the network’s primary and most widely run validator client. The team builds and ships Solana protocol software, including major upgrades like Alpenglow that improved consensus and finality.

• Design, implement, and optimize AccountsDB storage paths: account file layout, account index, and caching layers.
• Reduce memory and disk footprint to keep validator hardware requirements manageable.
• Improve background services: flushing, cleaning, shrinking, and purging to lower write amplification.
• Optimize snapshot generation, loading, and index creation to speed validator startup and catch-up.
• Ensure correctness across forks, rooting, and crash recovery to preserve network integrity.
• Build and run comprehensive tests: stress tests, fault injection, and performance benchmarks.
• Collaborate with runtime, block production, and core protocol teams; maintain documentation and perform code reviews.

• 3+ years architecting data stores, file systems, databases, or high-throughput storage systems; BS in CS/Engineering or equivalent experience.
• Mastery of Rust, C, or C++ and strong understanding of storage architecture (on-disk formats, indexes, caching).
• Advanced knowledge of I/O subsystems, NVMe constraints, buffered vs direct I/O, and async interfaces like io_uring.
• Deep familiarity with kernel and memory management, custom alloc
