For our Wikibase Suite team, based in Berlin, we are looking for a permanent Senior Software Engineer (m/f/d), full-time or part-time, as soon as possible.

About the position & the team:

The Wikibase Suite is a software suite to collaboratively curate linked data that users can install on their infrastructure (also in the form of OCI container images). It is used by libraries, galleries, research groups, and the public sector alike. For example, the European Commission uses Wikibase for information around funded projects and their beneficiaries.

You will be developing open source software that puts user needs first and increases users’ satisfaction. At Wikimedia Deutschland we work towards a future in which people share the power to collect and organize the data that shapes humanity’s understanding of the world.

What you’ll be doing:

  • Participate in all the stages of software development as well as code, design, and architectural reviews providing constructive feedback
  • Be responsible for and present in all stages of the engineering work:
  • Be responsible for the technical direction of the team
  • Understand and discuss mid- and long-term implications of architectural resolutions and be able to communicate the impact of engineering decisions on our products
  • Maintain a good understanding of the technical aspects of the product roadmap as well as the team goals
  • Work with managers and technical leads to ensure engineering effort is focused on the most impactful areas for their team
  • Support the professional growth of other engineers together with engineering managers and technical leads
  • Engage in constantly improving the team processes and agile practices

What we offer:

  • You will be part of a cohesive and engaged team that fosters unity and supports each other
  • Flexible working hours adjusted to the team and people needs
  • A diverse and inclusive bi-lingual organisation where people are the first priority
  • An open-minded and positive organizational culture
  • Work in cross-functional teams towards a common goal
  • We dedicate one day per quarter in the department to work on any non-work-related project you want 
  • Opportunity for personal and professional development
  • 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 as well as a modern and centrally located office space in Berlin
  • 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
  • All overtime is recorded and converted into compensatory time off
  • This is a permanent contract

What makes you right for this role:

  • 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 experience with web development
  • You have worked with OCI containers (e.g. Docker, Docker Compose)
  • You like being in a team working towards a common goal, learning together, and supporting and lifting up your peers
  • You have an eye for software design and quality and you understand the importance of tests
  • You can recognize legacy code and know how to effectively deal with it
  • You like to participate in technical discussions and are open to new ideas
  • You are a fan of innovation and like to promote innovative approaches within the team
  • 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 at a professional capacity

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. We currently use Docker to provide Wikibase Suite to the users.

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. We list only a few of them here.


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!
