Senior Frontend Engineer - JTX

Jito Labs, best known for the Jito Block Engine and JitoSOL liquid staking on Solana, is hiring its third frontend engineer for JTX, its live onchain trading app. Two engineers have already built JTX to its current state; this hire will help take it from a working product to something that holds up under real trading volume and expands onto mobile.

The role covers the full client surface of JTX across web and mobile: order entry, market data, charts, positions, execution quality, onboarding, and the wallet flows underneath the trading experience. The stack is React 19 with TypeScript on Next.js, Jotai and TanStack Query for state, TradingView charts on a proprietary data feed, and Privy for wallet connections, with several live WebSocket streams to keep in sync.

Jito frames the hardest parts of the job as keeping many real-time data streams fast and consistent, maintaining performance in a data-dense trading terminal, and hardening wallet-signing and session security, all while a three-person team owns the entire client surface of a live exchange.

• Build and own the JTX client experience across both web and mobile
• Ship real-time trading interfaces including order books, charts, order entry, and position/fill visibility
• Hit tight latency and rendering budgets while working with multiple live WebSocket market-data streams
• Build wallet and signing flows, including self-custodial and embedded wallet onboarding
• Own shared component, state, and data layers that the rest of the product team builds on
• Make architectural decisions expected to hold as the codebase and user base scale substantially

• 5+ years building production frontend applications, including something real-time, data-dense, or financial
• Deep React and TypeScript expertise, including debugging rendering and performance issues
• Mobile development experience (React Native, Expo, or native iOS/Android)
• Strong fundamentals in browser performance, memory management, and websocket/network behavior under load
• Security-conscious instincts around wallet signing, key handling, and sensitive data logging
• Comfort refactoring and shipping within an already-live production codebase

This is Jito's third frontend hire for JTX, giving significant ownership over the trading app's client architecture at a company that already runs core Solana validator and MEV infrastructure at scale.
