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 (ask for details). 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.

Archetypical Users

• 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.

• Based in New York City and able to work on-site with the team.
