Overview
Join Jito Labs as a Senior Frontend Engineer to build and own the JTX trading app across web and mobile, focusing on real-time trading interfaces and architectural decisions. JTX is our trading app, and it runs on the fastest market infrastructure on Solana, which we also built. What nobody has done yet is make that speed something a trader can feel. That is this job. JTX is live. Two frontend engineers built it to this point and you would be the third. The work now is one to a hundred: harden what exists, make it hold up under real volume, expand onto mobile, and raise the ceiling on every screen a trader touches. We're a small team with product-market fit. That means:
- •High ownership: every team member drives significant technical decisions and shapes our product roadmap.
- •Fast execution: we ship rapidly and iterate based on real-world feedback. Progress, not motion.
- •High quality bar: the details are the product. We don't trade them for speed.
What You'll Do
- •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
What We're Looking For
- •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
