Developers working on Apple Products rely on Apple Frameworks every day for productivity and integration with the Apple ecosystem. For a great developer experience, we are continually enhancing and improving our client-side frameworks. We are seeking a developer to build abstractions and help build developer-friendly, on-device libraries which encourage best practices for both device and cloud efficiency.
We’re looking for a developer who enjoys building foundations for other developers. The iCloud Developer Experience team collaborates with framework and tool engineers across Apple, works to understand their needs, and builds shared frameworks for them to use. We provide consultation and code for those making user interfaces, code generators, cloud services, and all the pieces in between. This position requires a highly creative individual who can critically listen to the diverse visions and concerns of multiple teams, synthesize and iterate on common solutions, and collaborate with teams to adopt them. Implementing this common infrastructure not only affects design decisions on developer-facing tools, but also future products across the Apple ecosystem. As Developer Experience engineer, your primary development environment will be the Xcode IDE.
