Jito Labs is a company that develops MEV (Miner Extractable Value) software for the Solana blockchain network. Their tools are designed to optimize the performance of the Solana blockchain by enabling validators, searchers, and stakers to improve trade efficiency and maximize profits. Jito offers products like the Block Engine, Bundles, and ShredStream, providing ways for validators to earn more from traders' Bundles while enhancing the decentralization and health of the Solana network. They offer a liquid staking pool and strive to leverage MEV for the benefit of the network, minimizing negative impacts on other users and applications on Solana.

📋 Description

• Build and own the JTX client across web and mobile • Ship real-time trading interfaces: order books, charts, order entry, positions, fill and execution visibility • Hit tight latency and render budgets against streaming market data, and decide what belongs on the client versus the server • Build wallet and signing flows, including self-custodial and embedded wallet onboarding • Own the shared component, state, and data layers the rest of the product team builds on • Make architectural decisions that hold as the codebase, the team, and the user base grow by an order of magnitude • Ship fast, watch real users, iterate

🎯 Requirements

• 5+ years building production frontend, including something real-time, data dense, or financial • Deep React and TypeScript. You can explain why a component re-rendered and then fix it. • Mobile experience: React Native, Expo, or native iOS and Android • Strong fundamentals: browser performance, memory, websockets, network behavior under load • Security-first instincts around signing flows, key handling, and what should never touch a log • Comfortable in a codebase that is already live. You can refactor and clean up without stopping shipping. • Able to weigh business and engineering tradeoffs, and to explain complicated things simply.
