Apple Inc. has a Software Engineer position available in Cupertino, California and various unanticipated locations throughout the USA. In this role, you will design Swift-based APIs and develop software for a public user interface framework used on Apple’s operating systems. You will also design and implement the Swift-based software for a public user interface framework, used by Apple’s external developer community.

Responsibilities

Research requirements and precedent for novel APIs, collaborating with cross-functional partners (design, developer tooling, technical writing, hardware), and producing technical writing for API design proposal and documentation.
Using cutting-edge Swift language features, which Apple requests and uses to enable new APIs, implement the software and programmatic interface for those proposals; anticipate future framework evolution and understanding compatibility and performance concerns of framework changes on adopting applications.
Triage and prioritize bug reports from internal and external teams adopting the framework, requiring analysis and understanding of bug reports, reverse-engineering of applications, and constructing test cases.
Provide API assistance and guidance for adopting teams, investigate framework requirements for new user features.
Debug application issues with the framework, analyze performance improvements, integrate fixes, and write framework tests to validate API use to ensure high quality changes and prevent binary compatibility regressions.
This is a 40 hours/week position.
