Jito Labs - Senior Frontend Engineer
Requirements
• Attention to detail bordering on obsessive. You can look at a screen and say what is wrong with it, and it bothers you until it's fixed. • 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 • Relevant Background • If you have experience in any of the following, you may be a good fit: • Trading terminals, exchange or brokerage frontends • Consumer fintech apps at scale • Charting, time series, or high-frequency data visualization (canvas, WebGL) • Solana or EVM app development, wallet integrations, transaction signing • Maintaining a public TypeScript library or design system • $175,000 - $195,000 a year
Responsibilities
• 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
