Description

You’ll join an internship program focused on building real product interfaces for users. Work primarily includes React (Next.js) with SSR vs SSG, component architecture, and responsive UI development. You’ll also contribute to animations, accessible UI components, and data fetching with SWR/React Query plus GraphQL API integration.

Responsibilities

  • Build frontend features using React (Next.js), with clear component architecture and prop design

  • Style responsive interfaces with Tailwind CSS and utility-first patterns

  • Implement accessible components with Radix UI (ARIA, focus management)

  • Create micro-interactions and animations with Framer Motion and GSAP

  • Integrate data fetching with SWR or React Query (caching, revalidation)

  • Connect to GraphQL APIs and build reusable UI components/design systems

  • Use clsx/classnames for conditional styling

  • Gain hands-on exposure to backend technologies including Elixir and the Ash framework

Requirements

  • At least one project on GitHub (solo or team)

  • Currently a student (any year)

  • Build for real users, not tutorials

  • Ask why a feature is needed before building it

  • Solve problems, not just write code quickly

  • Willingness to learn new things

Benefits

  • Possible full-time offer after the internship

  • Real product code (not mockups)

  • Mentorship from senior engineers and product designers

  • Flexible schedule around student commitments

Application Process

  • GitHub review is the most important part of the application

  • 30-minute call + short quiz

  • Office talk invitation

Applications without GitHub won’t be considered.
