The Wikimedia Foundation is looking for two Software Engineer III’s to join the App Growth and Moderator Tools Engineering teams within the Core Experiences engineering group. App Growth: The App Growth team has a clear and ambitious goal: make the apps the destination for knowledge lovers and grow our active readership. As a web full stack mid-career Software Engineer III supporting the Mobile Apps teams you will build features that create natural handoffs from the web to the app and landing users in exactly the right place — for example, prompting a reader to try a personalized reading list in the app, creating a game that is integrated within the apps as a webview; or when someone tries to edit there is a smooth hand off to the web editing experience. This is not a native iOS or Android role. The role is focused on web-first product experiences, APIs, and platform integrations that can be reused across mobile web and native app surfaces; to help us scale features across platforms and create compelling features that deepen reader engagement and increase user retention. To ensure there are enough opportunities to communicate, this role with the App Growth team needs at least four hours of your workday to occur between 14:00 UTC and 21:00 UTC. Moderator Tools: On the Moderator Tools team, we build and improve tools for Wikimedia’s volunteer patrollers and administrators, improving their ability to review and take action on bad content across Wikimedia projects. Our focus right now is on exploring ideas for a centralized venue to identify moderator needs by advancing a unified personal Dashboard that supports the full reader-to-new-editor-to-new-moderator journey. In order to see those bold ideas through, the team is looking for a software engineer III to join the team. As an engineer in the product and technology department, you will be responsible for building out components for our product user experiences in the Dashboard and other projects since the team maintains a handful of MediaWiki extensions and “off-wiki” projects related to The Wikipedia Library. In this role, you will work in a remote environment, where we value teamwork and a consensus-oriented approach. You get to write open-source code for collaborative experiences supporting over half a billion pages accessed per day. To ensure there are enough opportunities to communicate, this role with the Moderator Tools needs at least four hours of your workday to occur between 14:00 UTC and 20:00 UTC.
