Senior Backend Software Engineer (Java/Kotlin) (f/m/d)

Job description

Hi! We are looking for people to help us to deliver good quality products for our customers and colleagues (internal users). Our goal is to increase the engagement of our customers with Zooplus and to do it we have in place these five teams in which ones you may fit:

Loyalty Area

  • Autoshipment: We created this product to allow our customers to have recurrent orders at home with the minimum effort from their side, increasing loyalty and satisfaction. We are the owners of a legacy app in PHP and currently we are redoing it in Kotlin + React. First deployment of the awesome new app is already in Sweden. We like to work sometimes in pairs, trying to expand our expertise area sharing front & back and learning together new skills.
  • Rewards: Once we made a purchase in our shop, we would like to reward you with some bonus points or stamps for future orders. We make this happen with several applications currently in Scala but moving them to Kotlin + React. We have a quite intense usage of database and a big amount of transactions.
  • Discounts: It is great to have a permanent discount in the shops you usually buy. We provide that discounts for one or three years to save a lot of money. Our apps are built in Java but also planning to move to Kotlin + React in this new phase getting the chance of new developments.
  • Coupons: Discounts, free shipping, extra points... whatever you need we can make it! We support all the company coupon strategy. Recently we delivered "My Coupons Page" and now we will rearrange all of our data for future faster developments. We work with Kotlin + React in the new developments and also we have some legacy parts in Java. 

Pricing Area

  • The daily tasks are related to developing new features, maintaining team products and improve all the infrastructure we need for it, so we also would like to have a colleague that likes to be cross-functional.
  • We like to learn and deliver good quality products and for that we think that continuous delivery, clean code and DevOps mindset it is the best way to do it.
