We focus our efforts on the overall web user experience of the various Wikimedia projects, with a particular emphasis on Wikipedia on the desktop and mobile websites. We're currently working on a refresh of the desktop web experience and are exploring a future focused on growing our platform capabilities and working with our communities to improve the flexibility and consistency of the user experience across the desktop and mobile web.

You are responsible for:

• Improving the Wikipedia product experience
• Iterating on new products and features through collaboration with designers and product managers
• Writing multilingual and accessible JavaScript, CSS, and PHP
• Creating and maintaining internet APIs with server scripting languages
• Instrumenting components to monitor feature and quality characteristics
• Leveraging caching and persistence technologies

Skills and Experience:

• 4+ years related professional experience in functional programming or OOP
• Experience building user-friendly features and software components with good performance
• Focused software engineering: you enjoy writing unit and integration tests, proactively addressing security and code review feedback, and thoughtfully balancing architectural tradeoffs

Qualities that are important to us:

• A desire to make meaningful contributions to knowledge equity, free culture, and open access
• An emphasis on communicating clearly in both synchronous and asynchronous channels

Additionally, we’d love it if you have:

• Fluency in one or more regional languages in Africa, Asia, or Latin America
• Practical skills with Vue.js or React
• Project work in data science, machine learning, AI (especially on natural language)
• A history of open source contribution
• Bachelor's, master's, or doctorate degree in computer science, management information systems, or STEM field (or equivalent certification)
• Familiarity with Wikipedia / wikitext / markdown editing or content management systems (e.g., MediaWiki, Drupal, WordPress). We grow and care for MediaWiki and Wikimedia specific services. MediaWiki is an open source, PHP, MySQL, and JavaScript web application that powers Wikipedia and other Wikimedia Foundation websites. It has been incrementally developed for over 15 years to become a richly featured wiki engine and the basis for hundreds of extensions and skins, and has a vibrant volunteer community. Our services utilize a number of technologies.
• Experience developing for markets in Africa, Asia, or Latin America.
