Role Overview

We are seeking a technically sharp and proactive Web Development Intern to help optimize the digital front door of our global challenger. In this role, you will go beyond basic content management to build the code and architecture that sits behind our Storyblok setup.

We consciously choose quality over quantity. Our development team is intentionally small and made up of engineers who have built and scaled products used by hundreds of millions of people worldwide. You will work directly with them from day one and see firsthand how strong technical decisions are made in a high performance environment.

Key Responsibilities

Technical Development

  • Develop and improve custom components and technical infrastructure within Storyblok.
  • Write clean and scalable JavaScript and TypeScript code in our frontend environment.
  • Implement new landing pages and features based on marketing and product needs.
  • Contribute to improving the structure and maintainability of our frontend codebase.
  • Build solutions with long term scalability and maintainability in mind. AI tooling such as Claude Code may be used, but the delivered code must be clean, well structured, fully understood, and production ready. The tool is the means, not the excuse.
