Job Description
Jito Labs is architecting the future of high-performance distributed systems on Solana. We're the team behind Jito-Solana, the leading MEV Solana client, and the Jito Block Engine, which has revolutionized block building on Solana. The Block-Engine has generated roughly 4.5 million SOL for validators and stakers over the past year. Our latest product, BAM, reimagines Solana market structure and the transaction supply chain with a heavy emphasis on performance, reliability, and transaction privacy. We're looking for a senior systems engineer with strong Linux systems and low-level performance experience who enjoys working at the boundary between software, operating systems, and hardware.
Why Jito We're a small, profitable company with product-market fit. That means: High ownership: You drive significant technical decisions and shape product direction Fast execution: We ship rapidly and iterate on real-world feedback Technical excellence: Complex problems, elegant solutions Sustainable: Strong financials let us focus on long-term impact, not runway About the Position We are seeking an exceptional
