The role.

Huge is looking for a Senior UI Engineer to join our Technology practice in Colombia. You’ll build high-performance web experiences for global clients, working closely with design, strategy, and QA, and helping raise the bar for the engineers around you.

What you'll be doing.

- Build scalable, highly interactive web applications on React, Next.js, and TypeScript.

- Architect frontend experiences on Headless CMS platforms (Contentstack), designing flexible content models and reusable components that editors can compose with confidence.

- Use agentic AI workflows to speed up component generation, refactoring, and delivery, and help shape how the team adopts these tools.

- Translate Figma designs into pixel-perfect code, bringing them to life with smooth, responsive animation that never compromises performance.

- Own front-end quality: ship accessible, standards-compliant, cross-device experiences that meet performance targets.

- Partner with UX, visual design, QA, and strategy teams to evaluate feasibility and refine requirements.

- Drive engineering rigor through Spec-Driven Development, clear documentation, and code reviews in a fast-moving agile environment.

- Mentor junior engineers, troubleshoot complex issues, and support global client teams on post-launch enhancements.

What we'd like to see.

- 5+ years building large-scale web products in agile, cross-disciplinary teams.

- Deep expertise in React, Next.js, and TypeScript, plus modern CSS and preprocessor solutions.

- A track record of using AI coding tools (e.g., Claude Code, Cursor, GitHub Copilot) in day-to-day UI work, with a clear sense of where they add value and where they don’t.

- Experience delivering WCAG-conformant interfaces and improving Core Web Vitals through tools like Lighthouse.

- Bachelor’s degree in Computer Science (or equivalent experience) and advanced English proficiency (C1+).

Nice to have.

- Hands-on experience with Contentstack or another headless CMS.

- A portfolio of frontend animation and motion design work.
