APPLE INC has the following available in Cupertino, California and various unanticipated locations throughout the USA. Ensure the accurate and precise presentation of innovative computer graphics content on augmented reality (AR) and virtual reality (VR) devices. Use combinations of writing automated tests as well as subjective human tests to detect flaws and correct them. Develop interactive AR/VR computer graphics programs that run in real-time, designing and implementing the architecture and framework of the internal developer-facing API. Make software changes that balance comfort with aesthetics using heuristics that have been proposed, and validate those changes. Inspect and review computer program code written by others, designing test procedures to assess the quality of outputs from those computer graphics programs. These include test programs that assess individual pipeline stages used for rendering, as well as automation written in Python that drives the entire system end-to-end. Fast-prototype designed tests with follow-up iterations, by managing experiment equipment for testing and work closely with internal teams to meet the quality requirements of graphics content presentation throughout the release process.
