As a Senior Front-end Developer you maintain the balance between creativity and functionality for our web shops, and you coach your fellow developers.

    • You actively coach your fellow developers and continuously provide them with constructive feedback.
    • You objectively consider technical choices, such as our architecture, tools, and processes, and don’t cling too tightly to previously made choices or existing information.
    • You keep an eye on the performance of the webshop and analyze how you can improve this.
    • You have to play foosball every day.

    Description Senior Front-end Developer

    “Morning!” You start a new sprint today, in which you and your team continue work on the new search functionality. Together with the UX Designer and your fellow developers, you discuss how to approach the first story. You pair up with the PHP Developer to make sure the right data is available. Afterward, you help the Junior Front-end Developer in your team to process the semantically correct HTML, the structured CSS, and the Google-friendly JavaScript.

    You’ll have to deal with the Pull Request later, since the end of the day involves a meeting with a couple of other enthusiastic developers. You have an idea for the implementation of a new technology that should reduce the Time To First Byte by 20%.

    • You understand version control, especially Git(hub).
    • You have at least 6 years of experience as a Front-end Developer in a similar environment.
    • You're highly knowledgeable about ES.Next, React, CSS-in-JS, and composition.
    • You’re a pro in HTML, CSS, and JavaScript.
