About the job:

Dimelo’s R&D department is looking for a Ruby / Rails Intern to join its experienced team of 6 developers in its offices in the heart of Paris’s 9th district.

Dimelo is a fast­growing independent software vendor delivering SaaS products that enables customers such as Orange, BNP Paribas, Canal+, Deutsche Bahn, Ooredoo, Axa (and many others), to manage their digital customer care. We developped 4 complementary products:

  • Dimelo Communities enables companies to build user communities for branding, peer­support and customer self­care purposes across the web and mobile devices
  • Dimelo Chat is a web live­chat solution featuring powerful behavioral targeting engine through an easy setup.

  • Dimelo Digital is an central engagement hub for customer care that unifies Dimelo solutions (Communities, Mobile, Chat), Social Media channels (Facebook, Twitter...) and customer service channels (such as forums, blogs, communities, SMS, email).

Job description

You’ll work closely with the other R&D developers and will have a direct impact on software used by top brands to manage their customer relationship. You’ll be implementing and improving features on all parts of the stack, while monitoring and the stability and performance of our applications.

We are very serious about our products but we also like to relax, for example we have a permanent football table contest and regularly schedule drinkups.

You’ll benefit from good working conditions: dual screen, good seating and powerful linux/mac boxes.
