RESPONSIBILITIES
- Own the front-end architecture of a high-throughput, real-time trading application.
- Design, build, and maintain production-grade applications using Next.js, React, and TypeScript.
- Implement pixel-accurate, accessible, and responsive UI systems under strict performance budgets.
- Lead complex feature development end-to-end, from technical design to production rollout.
- Optimize rendering paths, state management, data flow, and bundle size for sub-second interactions.
- Integrate deeply with REST and WebSocket APIs powering live market data and execution flows.
- Collaborate tightly with product, design, and backend engineers on advanced trading workflows.
- Set and uphold engineering standards around code quality, testing, performance, and maintainability.
- Mentor other engineers and raise the bar for front-end execution across the team.
- Contribute across the stack when needed (API design, data models, infra tradeoffs).
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 (WebSockets, streaming updates, event-driven UI).
- Strong instincts around state management, data consistency, and UI correctness under load.
- Comfort reasoning about backend systems (Node.js, databases, 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.
NON-NEGOTIABLE
- Speed — in execution, iteration, and UI responsiveness.
- Obsession with performance, not just aesthetics.
- High ownership, low ego, zero tolerance for sloppy systems.
PREFERRED
- Prior experience in fintech, trading platforms, or other latency-sensitive products.
- Open-source contributions or technically substantial side projects.
- Comfort operating in fast-moving, high-accountability startup environments.
