Senior Data Visualization Developer

Data wrapper’s mission is to help the world create better visualizations. We provide an easy-to-use, free online tool to create charts, maps, and tables. It’s used by thousands of people every day, among them brands like The New York Times, Quartz, and Five Thirty Eight .

We strive to make best-practice data visualization available to everybody. To do that, we’re looking for a talented new team member that can help us build the next generation of data visualization features.

We’re looking for someone with multi-year practical experience in building web-based interactive data visualizations as well as a solid background in information visualization theory. A basic background in cartography is a plus.

• SVG and Canvas APIs
• The D3.js visualization framework
• Svelte 3, Vue, React, or a similar reactive framework
• Modern JavaScript (ECMAScript 2021)

• A strong computer science background (including common algorithms, complex data structures, etc.)
• An information visualization background (including visual perception, cognition, gestalt principles)
• A basic foundation in linear algebra and computational geometry

We welcome applicants with an innovative and open mindset who can prototype ideas quickly. You can join remotely (timezones around Berlin, GMT, CET or EET) or get a desk in our Berlin office.

This role will particularly focus on front-end data visualization rendering and display. That includes building new visualization types, extending the customization options of our existing visualizations, and building reusable components for different needs.

Data wrapper enables people worldwide to build great charts, maps, and tables. We’re used by:

• Media and news publications like The New York Times, The Washington Post, Five Thirty Eight , and Quartz
• Financial institutions like Fitch Ratings and Moody’s
• Governmental institutions and NGOs like the United Nations, the European Commission, and the World Economic Forum
• Cities and municipalities like Madrid, London, and New York City
• And many more, including statistical offices, market research firms, and design agencies

• Growth, development, and personal initiative. We’re a small startup, which means there are lots of opportunities to grow and learn.
• Few meetings. We try to keep meetings infrequent and short. Instead, we believe in written discussions, good meeting preparation, and short 1:1 check‑ins.
• Competitive compensation and benefits, including 30 days of paid vacation, a 2000 euro education budget, and the latest and greatest hardware of your choice.

Does all of this sound like something you’d like to do? Great! Send along your CV and tell us about your previous experience and how you think it makes you a good fit for this role.

We’re looking forward to hearing from you!
