About the role
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.
