About the position:

You will be working with the team that develops and improves the software behind the Wikidata project. Wikidata is a free and open knowledge graph that can be read and edited by both humans and machines and is a part of the Linked Open Data Network. You will be developing open source software that puts user needs first and increases users’ satisfaction. Wikidata has the clear goal of giving more people more access to more knowledge and you will be part of that!

- You will have a noticeable impact on one of the top visited websites in the world
- Flexible working hours adjusted to the team and peoples’ needs
- Work in cross-functional teams towards a common goal
- You will be creating open source software on a daily basis - almost all software created by Wikimedia Deutschland is published under open source licences.
- A working culture that supports releasing a good product over releasing in order to meet a deadline
- We dedicate one day per quarter in the department to work on any non-work-related project you want
- Flexible working hours adjusted to the team and peoples’ needs
- You can attend local user groups during working hours
- Opportunity to improve your presentation skills and to share your favourite topics in internal presentations to the other engineering teams
- Opportunity to go to conferences, both as participants and contributors
- The possibility of working from home when needed as well as a modern and centrally located office space - in the heart of Berlin - with a fully equipped kitchen, different sized meeting rooms and hybrid working spaces
- And a lot more: 30 days of holidays, public transport allowance, access to complementary pension benefits, continued salary in the event of ill children, free-of-cost external life coaching
- This is a permanent contract
- Learn more about our team by visiting our Wikimedia Tech News Blog.

About you:

- You are passionate and care about software.
- Your background is not important as long as you have a solid understanding and experience with object oriented programming and basic experience with web development.
- You have an eye for software design and quality and you understand the importance of tests.
Experience with graph databases or MediaWiki is a big plus.
- You like working in a team working towards a common goal, learning together, and supporting and lifting up your peers.
- You are not afraid of making mistakes and you learn from them.
- You want to keep learning and developing yourself.
- You are able to communicate in English with professional proficiency.

Technologies we use:

Most of our server side code is written in PHP and for version control we use Git. We use Vue.js and TypeScript for our modern frontends. We also keep migrating our legacy code into these and newer technologies. Also, testing is important to us; we use testing frameworks and practice continuous integration across our projects.

Knowledge and experience in these technologies is not a requirement. We believe they all can be learned on the job and WMDE, your team, and your line manager will support you in this learning.


Then apply now! Send us your detailed application documents (Resume & Motivational Letter (yes, we read them)) via our job portal. Our HR team will be happy to answer your questions. We kindly ask you to refrain from application photos and information on date of birth, marital status and parents. We look forward to hearing from you!
