About You

To succeed as a Frontend Engineer at Qonto, you will need to demonstrate:

1. Proficiency in frontend engineering: you have at least three years of professional experience using React.JS or Ember.JS, as well as HTML and CSS. We don’t use CSS libraries such as Tailwind, so you will need to know how to react pure CSS.

2. Attention to detail: you strive for excellence in every aspect of your job. You don’t gloss over minor issues and you understand that great work is the accumulation of many small things done right.

3. Communication skills: you explain your thoughts in a clear, organized, concise and accurate manner.

4. AI fluency & good judgment: you can leverage AI to move faster (research, writing, coding, testing) while staying critical, validating outputs, and protecting the product’s reliability and user trust

At Qonto we understand that true diversity isn't just about ticking boxes on a hiring checklist. Apply regardless of the boxes you tick! Who knows? You may have the missing piece of the puzzle we've been searching for all along.
