Twelve-time Webby award-winning is the world's largest freelancing and crowdsourcing marketplace. We connect millions of employers to freelancers across the globe, and every day thousands of jobs are described, bid on, negotiated, and managed through our site.

We think it is pretty cool that our dataset details a real life economy, where work is undertaken in every area you can think of. From design, writing, data entry and software development; through to sales, marketing, accounting and legal services - even NASA uses us!

Mobile is intrinsic to our global business, with 80% of our users utilising our mobile platforms to interact with the site. And of course, iOS plays a central role in this. In this role, you will be responsible for building scalable mobile applications for the iOS platform, maintaining them and adding new features as we update the desktop site. And not only will you build software that scales, but you will have the chance to ship code on your first day, and get instant feedback from millions of users worldwide.


  • A tertiary degree in Computer Science / Engineering (or Related). MS or PhD a plus
  • Proven experience building iOS apps with published work on the App Store
  • A deep familiarity with Objective-C and Swift programming languages
  • Experience working with iOS technologies such as UIKit, Core Data, Core Graphics, localisation, etc.
  • Solid experience in Git, Cocoapods, JSON, REST
  • Strong understanding of the full mobile development life cycle
  • Able to run performance analysis and optimise away application bottlenecks


This won’t be a cog-in-the-machine type of job; you will be joining a rapidly growing global technology company that values attitude and capability over experience, so if you are looking to make a difference and be rewarded for your efforts, this is the place for you.

We are striving to build one of the biggest sites on the Internet, so help us scale for 100+ million users, while enjoying all the perks of working in tech - fun atmosphere, smart people, awesome office, fully-stocked kitchens, social events, hackathons, your choice of platform, and more!
