Job ID: 35677
Date Added: 10/08/2025
LOCATION: Cupertino, CA (on-site Tuesday – Thursday)
ANTICIPATED DURATION: 12 months
We’re looking for a creative and resourceful macOS developer with 3-5 years of experience to support the lead engineer on a large internal tools project. This person will assist in implementing new features, testing existing code, and fixing bugs. The project involves building internal extensions to a suite of established, consumer-facing macOS applications. These extensions are designed to streamline the content creation workflows of our creative design and production teams. The applications being extended have a mature and complex codebase, written predominantly in Objective-C (~90%). All new developments are being made in Swift, with SwiftUI used for the user interface layer. Success in this role will require deep knowledge of macOS development and strong experience working across both Objective-C and Swift, including handling interoperability between the two. You should be comfortable navigating a large legacy codebase while contributing modern Swift code that integrates cleanly and safely. A significant portion of this role will focus on testing new and existing features, as well as performing quick-turnaround bug fixes as the need arises.
