The Skillset You'll Bring:

3+ years of professional experience building web applications and data-driven tools

Strong experience building production applications with technologies like React, NextJS, and TypeScript

Experience with modern CSS (Tailwind) and component libraries (Radix UI) for building design systems

Bonus Points:

Experience with technical visualization tools (WebGL, D3.js, Apache ECharts) and time-series data

Background in scientific computing or technical data visualization

Experience building tools for technical users (dashboards, data-editing environments)

Built and launched side projects with consistent usage traffic
