Fullstack Developer (Freelancer) // Wikimedia Deutschland

February 20, 2017
Wikimedia Deutschland – Gesellschaft zur Förderung Freien Wissens e. V. is a non-profit organisation based in Berlin, Germany. With more than 80 employees and about 50.000 members, it is the oldest and largest of more than 40 independent chapters of the international Wikimedia movement. The most well-known Wikimedia project, the free online encyclopedia Wikipedia, is used by millions of people across the world every day and is continuously updated and improved by millions of users. As a Software Developer you will work on our existing and future online fundraising donation application and possible cross-department projects at Wikimedia Deutschland. In the software development department we are building open source software that impacts the world.

We are looking for someone to join one of our agile development teams in our office in the heart of Berlin.

About you

  • You care about software; you have a passion which you can clearly convey by your actions rather than personal statements on your CV alone
  • You have an eye for software design and quality
  • You can recognize legacy code and know how to effectively deal with it
  • You are able to communicate fluently in English in a multidisciplinary team
  • For you it’s more than a job

Our development teams are cross-functional, self-organizing and highly autonomous. No single team leaders or middle management. You’ll be working directly with the product owner. Among other things, testing, refactoring, and pair programming are encouraged. We’re constantly trying to improve the way we work.

What we are offering you

  • We have internal presentations by our developers on topics they are enthusiastic about
  • You can attend local user groups during work time and you are encouraged to do so
  • You will have a noticeable impact on one of the top four visited websites in the world
  • We regularly go to conferences, both as attendees and participants

Most of our server side code is written in PHP. A lot of our projects have a HTML 5 & JavaScript frontend, which interact with server side backends via web APIs. We test our code with PHPUnit and QUnit, and with browser tests written in Ruby. Some of our code is written on top of the MediaWiki framework, some of it is entirely in-house and for newer projects we use libraries such as Symfony components and Doctrine.

We’re interested in candidates from any background, as long as you have a solid understanding of Object Oriented languages and basic experience with web development.

Here is an (incomplete) list of technologies we’re currently using:

  • JavaScript, PHP, Ruby
  • MediaWiki, several MediaWiki extensions
  • PHPUnit, QUnit, Selenium, Cucumber, PHPCS, PHPMD, JSLint, Rubocop
  • Git
  • MySQL, SQLite
  • Composer
  • TravisCI, ScrutinizerCI, Jenkins
  • Wikimedia Labs infrastructure
  • Phabricator
  • Linux server, nginx
  • Puppet, Vagrant

All software we develop is open source, we also contribute back to various projects we use, including some of the ones listed above. Many of our components are also published in a format that allows reuse outside of our own projects.

To begin your application, please answer the questions and complete the exercises at http://hr.gs/amawzing-fullstack. If the results are satisfactory, we will be in touch. When you have any questions please contact sandra.muellrick@wikimedia.de.
