As a full stack engineer – with both backend and frontend experience – you will be responsible for making changes to both our javascript-based frontend and our PHP-based backend code. For this role, the majority of your time will be spent on the frontend user experience and our skins-based templating system, but you will also be asked to make changes to backend services, metrics, and other non-user-facing code.  You should be comfortable with benchmarking, running synthetic tests and have an understanding of XSS and how to prevent them, as well as productioning backend services. 

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:

• 2-5 years related professional experience in a related field
• Experience building user-friendly features and software components with good performance
• Experience working on backend services with high availability and uptime
• 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 in 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 in or interest in developing for markets in Africa, Asia, or Latin America.
