About the role

Key responsibilities & impact

Design, implement, and optimize AccountsDB’s core storage paths, including account file layout, account index, and read/write caching layers
Reduce memory and disk requirements as account state grows
Improve flushing, cleaning, shrinking, and purging processes to reduce write amplification and maintain predictable resource usage
Optimize snapshot generation, loading, and index generation to shorten validator startup and catch-up times
Ensure account state correctness across forks, rooting, and crash recovery
Create and execute comprehensive storage-engine tests, including stress tests, fault injection, and performance benchmarking
Collaborate with runtime, block production, core protocol, and other Solana client teams
Maintain AccountsDB documentation and conduct peer code reviews
Contribute to Anza’s Agave client and the broader Solana network

Requirements

What you’ll need

Bachelor’s degree in CS, Engineering, or relevant practical experience
3+ years architecting data stores, file systems, databases, or high-throughput storage systems
Mastery of Rust, C, or C++
Comprehensive grasp of low-level storage mechanics, including memory-mapped files, page caching, index structures, on-disk formats, and garbage collection mechanisms
Advanced knowledge of kernel-level and hardware I/O pipelines, NVMe constraints, buffered versus direct I/O, and modern async interfaces like io_uring
Strong understanding of custom memory allocators and Linux kernel scheduling, page management, and I/O handling under intense throughput
Proven experience building concurrent systems, with deep knowledge of lock overhead, lock-free structures, and hardware memory models
Track record of profiling and tuning low-level code with emphasis on hardware mechanics, memory bus saturation, and CPU cache efficiency
Ability to debug intricate software architectures, isolate performance bottlenecks, and execute robust engineering solutions
Exceptional communication skills and a team-first mindset
Preferred: Experience with LSM trees, B-trees, or hash-based storage engines such as RocksDB, LevelDB, or WiredTiger
Preferred: Background in versioned or multi-version data stores, snapshotting systems, or blockchain state storage
Preferred: Familiarity with Linux, systems automation tools, and systems architecture
Preferred: Active participation in Bitcoin/Ethereum/Blockchain projects or the open-source community
