Portal Front-End Developer

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Portal Front-End Developer based in Switzerland.

We are seeking an experienced Front-End Developer to build a secure, user-friendly portal connected to a new e-commerce website experience. You will contribute to two key workstreams: a participant-facing portal for a structured 12-week brain health program and a lightweight administrative portal for user management. Working closely with backend developers, designers, and QA teams, you will translate approved designs into responsive, accessible, and reliable interfaces. The project follows an MVP approach, giving you the opportunity to influence implementation decisions and validate scope before development begins. This is a focused contract engagement with clearly defined deliverables and potential opportunities to contribute to a future development phase.
