About Genius
Genius is a consolidated on-chain trading terminal positioning itself as 'the final on-chain terminal' for crypto traders. It provides near real-time trade execution by aggregating quotes from over 150-300 DEXs across 8+ networks (Solana, Ethereum, Base, BNB, Arbitrum, Optimism, Polygon, Avalanche, Sonic, HyperEVM, Hyperliquid, Sui), and supports advanced order types such as limit, market, take-profit and stop-loss orders. Its native Genius Bridge Protocol enables natively cross-chain order fulfillment without traditional bridging, and its 'Ghost Orders' feature provides transaction privacy through order splitting across wallets. The platform is building out additional products including USDgg, a yield-bearing stablecoin backed by cross-chain swap fees, general asset yield routing across protocols like Aave, Morpho, Euler and Jito, RWA and stock trading, and future prediction markets and crypto options. Genius uses Turnkey and Lit Protocol for non-custodial wallet infrastructure and has been audited by Halborn, Cantina, HackenProof and Borg Research. It serves individual crypto traders looking for an efficient, private, multi-chain trading interface, and recently announced investment from YZI Labs.
Skills
About the Role
You will own the front end architecture of a high-throughput, real-time trading application. You will design, build, and maintain production-grade applications using Next.js, React, and TypeScript. You will implement pixel-accurate, accessible, and responsive UIs under strict performance budgets and optimize rendering, state management, data flow, and bundle size for sub-second interactions. You will integrate with REST and WebSocket APIs powering live market data and execution flows, lead complex features end-to-end, set and uphold engineering standards for code quality and testing, mentor other engineers, and contribute across the stack when needed.
Requirements
- 6+ years of professional front-end engineering experience with clear ownership of complex production systems
- Expert-level mastery of React Next.js and TypeScript in high-performance environments
- Deep understanding of front-end architecture rendering behavior and performance optimization
- Proven experience with real-time data systems including WebSockets streaming updates and event-driven UI
- Strong instincts around state management data consistency and UI correctness under load
- Comfort reasoning about backend systems including Node.js databases and cloud infrastructure; hands-on experience is a plus
- Track record of shipping and maintaining features that operate at scale
- Ability to make high-leverage technical decisions independently
