Software Engineer, iOS

Come build the premier mobile Wikipedia experience The Wikimedia Foundation is looking for an iOS Software Engineer to join our team, reporting to the Mobile Apps Engineering Manager. You will work closely with the rest of our small, collaborative group to iterate on new ideas for the award-winning Wikipedia iOS app. In this role, you will create new features, fix bugs, and define the future of Wikipedia on mobile devices.

Each day, millions of people use the open source Wikipedia app in over three hundred languages. Help us thoughtfully craft user experiences that empower and delight our users as they read and contribute to the world's largest resource for free knowledge.

You are responsible for:

  • Writing clean, concise code in Swift
  • Working with other engineers through discussions, code review, and more
  • Collaborating with designers, product managers, and other engineers to iterate on new features
  • Ensuring the quality of the app through thoughtful code architecture decisions and automated testing
  • Triage issues reported by our users and debug, track or resolve them

Skills and Experience:

  • At least 1 year of iOS development experience in Swift. (Our iOS engineers are excited to share knowledge and tips they've picked up over the years - and also look forward to learning from you)
  • At least one app in the iOS App Store that you've contributed to. (We'd love to see what you've been working on.)
  • Excellent written and verbal communication skills (Our team is remote, but we still enjoy close collaboration)

Qualities that are important to us:

  • A desire to learn and discover - about iOS development, about what the root cause of an obscure bug is, about how the Wikipedia communities operate, and more.
  • Constantly improving your craft in pursuit of creating the best possible user experiences and solving complex problems
  • Proactively finding and reporting potential bugs or user experience issues for discussion with the team
  • We are a global organization with flexible work schedules, but we're also collaborative. To ensure there are enough opportunities to communicate, this role needs at least four hours of your work day to occur between 14:00 UTC and 22:00 UTC.

Additionally, we'd love it if you have:

  • At least 2 years of experience in software development
  • Some Objective-C experience. Like many apps that have been around for a while, the Wikipedia app is a mix of Swift and some legacy Objective-C code. While you don't need to be an Obj-C expert, you shouldn't be terrified if you end up in an Objective-C class while tracking down the source of a bug.
  • Familiarity with the iOS Human Interface Guidelines and their implementation. (We're creative, while staying true to best iOS practices.)
  • Written unit and UI tests
  • Built web services or APIs
  • Built frontend web applications using JavaScript, HTML, and CSS
  • Experience collaborating with a globally distributed team
  • A history of open source contributions
  • Contributed to Wikipedia or other free knowledge projects
