Gevraagd wordt

As a Frontend Developer at Helloprint you work on making our platform the easiest and biggest one on earth by making sure our customers have the best user experience they can imagine! Our team consists of several Frontend Developers already, but can use more development capacity due to our rapid growth. You will be working on all the wishes of other departments and therefore meeting all Helloprint’s needs to be able to grow. If you are able to write high quality code at high pace within a dynamic environment you might just be the superstar we are looking for!

What you do

  • You will be working with a modern technology stack: PHP, HTML, CSS / SASS, jQuery, Angular, React, Vue.js etc.
  • Building a pixel perfect environment based on the design;
  • Giving our customers the best user experience they can imagine;
  • Developing in JavaScript, no matter what exact framework - you fully understand the fundamentals and principles of JavaScript;
  • Developing mobile-first solutions;
  • Implementing UX experiments (A/B tests);
  • Applying the best tech stack for the given situation;
  • Work closely together with other developers and a Product Owner in a Scrum team.

What a day looks like

9:00, you start your day with a cup of coffee and taking a look at the Scrum board. You mention that it seems like we’re not on track for the current Sprint and ask the Product Owner if everything is going well. Some of the developers had a problem which will be discussed during the stand-up.
10:00, just before the daily stand up you finished your last task for the sprint. You help a developer who has a problem with setting up a new UX experiment in the checkout of our Italian webshop. You saw directly what the problem was, and were able to help him finishing his tasks on time. Well done!
10:30, during stand-up your colleagues told about the issues they had, and you offered your help on that. You sit together and were able to think about a different implementation. That worked out well!
11:30, during the refinement session, it turned out that some tasks need more technical details before they can be estimated. As you have a lot of Javascript knowledge, together with the Product Owner you think about the proper technical implementation, and finish the description of the User Stories
13:00, it is time for a nice homemade lunch by JJ. During lunch you chat with some colleagues to see how everything is going.
14:00, after lunch you join a demo meeting of one of the other Scrum teams. They really worked hard to finish one of their projects, that looks nice!
16:00, you blocked some time in your agenda to think about a proper frontend architecture and possible JavaScript framework for a new project where we will replace the checkout of our webshops. You have some great ideas, and
involve the rest of the team to see what their thoughts are!
18:00, you make sure the Scrum board is up to date at the end of the day. Great day guys. See you tomorrow!
