About the iOS Developer Role

As an iOS Developer you will join the experienced Bipsync product development team, which is collectively responsible for several web, desktop and iOS apps, a browser extension and a suite of desktop plugins. You contribute toward the development of our iOS apps on iPhone and iPad, and in conjunction with the management team, shape the mobile strategy which is increasingly critical for our users.


  • Design and implement features that take advantage of the capabilities of iOS devices like the camera, microphone, GPS, etc.
  • Shape our applications so they can handle the synchronisation, storage and display of gigabytes of data while remaining responsive to the user.
  • Develop features to match our apps on other platforms.
  • Plan, prototype, build and deploy iOS software features in collaboration with the product team.
  • Create efficient, maintainable, testable code.
  • Collaborate with peers on interface design, code reviews and testing.
  • Learn from your team members and teach when you can.
  • Pragmatically analyse customer feedback and usage data to improve and iterate features.
  • Evaluate and identify new technologies for implementation.
  • Develop and communicate the mobile strategy in conjunction with the product and management teams.
  • Help to build-out the iOS team as the company and platform grows.

About You

You are an enthusiastic, knowledgeable iOS developer with an intuitive feel for what makes great software. You use and appreciate Apple products, and eagerly anticipate WWDC every year. You enjoy seeing code and feature development through the full lifecycle: from requirements gathering, specification and prototyping through to deployment and ongoing iteration. You’re a fast learner who will thrive in a rapidly evolving startup with continuous delivery and fortnightly product releases.


  • A relevant technical/computing degree is preferred, or an equivalent technical background. Essentially we need to see some examples or documented experience that demonstrates your technical skills.
  • Excellent ability with Objective-C and/or Swift. Knowledge of JavaScript would be ideal but is not crucial.
  • Confidence in designing and consuming REST / JSON web service APIs.
  • Substantial experience with iOS. In particular, familiarity with the UIKit and Core Data frameworks is desirable.
  • An understanding of Data Protection, Background Fetch, Push Notifications, Safari Extensions and Sharing/Action Extensions, and the implications they have upon iOS apps.
  • An appreciation of the challenges of multithreading.
  • Experience with source control (Git), unit tests, UI tests and other software development best practices.
