Overview

TradeGenius is building a next-generation crypto terminal and exchange, with the deepest network coverage of any terminal and the most liquid backers in the industry (details on request). Front-end is not decorative here: it is the conversion engine, the retention loop, and the brand differentiator. While this role is front-end focused, we value engineers who can contribute across the stack. We’ve processed over $1.5B in volume and serve 1.5M+ users.

Responsibilities
  • Architect, build, and maintain high-performance front-end applications using Next.js and TypeScript.

  • Implement pixel-perfect, responsive, and accessible UI components.

  • Collaborate with product and design to deliver seamless user experiences for advanced trading workflows.

  • Optimize performance across devices and browsers with attention to rendering speed, bundle size, and load time.

  • Integrate front-end with APIs and occasionally contribute to back-end development when needed.

  • Uphold best practices in code quality, testing, and documentation.

  • Mentor junior developers and influence engineering culture and standards.

Requirements
  • 4+ years of professional front-end development experience.

  • Expert-level proficiency with Next.js, React, and TypeScript.

  • Strong grasp of modern front-end architecture, performance optimization, and state management.

  • Experience integrating with REST and WebSocket APIs.

  • Familiarity with back-end concepts (Node.js, databases, cloud services, Postgres) is a plus.

  • Demonstrated ability to own features end-to-end in production systems.

  • Ability to operate independently in a distributed or remote-first environment.

  • Speed. Speed. Speed. Execution and iteration velocity matter.

Preferred
  • Prior experience in fintech, trading platforms, or real-time applications.

  • Contributions to open-source or technically substantial side projects.

  • Comfort with rapid iteration and startup velocity.
