Develop and optimize Solana’s AccountsDB storage engine, including indexing, caching, snapshots, background maintenance, and crash recovery. Improve validator throughput, latency, memory, and disk efficiency while ensuring correctness across forks. Build stress, fault-injection, and performance tests; profile low-level systems; collaborate with protocol teams; and document designs and review code. The role requires strong systems programming, storage architecture, Linux I/O, kernel and memory-management knowledge, concurrency expertise, and performance optimization experience.

Develop and optimize Solana consensus mechanisms, algorithms, and infrastructure for secure, scalable, high-performance blockchain operation. Responsibilities include improving validator coordination, testing through stress and fault-injection scenarios, performance benchmarking, security analysis, documentation, code review, and collaboration with protocol, security, and infrastructure teams.

Enhance and maintain the Agave client and Solana infrastructure by debugging, designing adversarial test frameworks, profiling performance, benchmarking solutions, collaborating across teams, and producing documentation to ensure reliability, security, and scalability.
