Do you enjoy building frontend products that make complex data easier to understand? Effektify is now looking for a Junior Frontend Developer to help build and improve a platform used to turn marketing, e-commerce, and business data into clearer insights and better decisions.

About the role

In this role, you will help build the frontend of a product where clarity, structure, and usability matter a lot.
