(Internship/Master Thesis) Getting reactive and cost-effective UIs with server-side rendering boosted by Hot-Wire


Modern SPA frontend technologies such as React, Angular or Vue are today almost the default way to implement a web user interface. The separation between the client and the server could be problematic not only because of the poor loading performance, but also because it forces to maintain a different model in the client and in the server that usually makes UI development costly and complex.

Approaches driven by a backend model tend to have a significantly higher productivity by exploiting a much simpler technology stack. However, the resulting UIs are less reactive and sometimes they offer a less attractive experience.

We propose to investigate a backend-driven approach for UI development with the innovative HotWire technology in order to improve the user experience of server rendered applications while preserving their main advantages.

In this role

The objectives of this internship include:

  • Explore the hotwire approach in order to assess its performances and development paradigm.
  • Implement real world scenarios with such approach and compare the results with their original implementations
  • Integrate the hotwire approach to the Spring MVC ecosystem
  • Present this new approach to the whole company

What we offer

  • A dynamic work and collaborative environment with a highly motivated multi-cultural and international sites team
  • Personal development through training and coaching
  • A culture of collaboration across all disciplines
  • The chance to make a difference in peoples’ life by building innovative solutions
  • High innovation and research backed up by collaboration with universities like EPFL
  • Various internal coding events (Hackathon, Brownbags), see our technical blog
  • Monthly After-Works organized per locations
  • Good work-life balance (2 days per week from home)

About your profile

  • Knowledge about web fundamentals (client, server, API, …)
  • Experience in web development (HTML, CSS, JS)
  • Experience in backend development (Ruby on Rails, Java)
