This role is perfect for a collaborative engineer who is passionate about the intersection of hardware and software and thrives on solving complex, open-ended problems.

Description As a key engineer on this team, you will tackle a wide range of complex challenges and collaborate closely with Performance, Power, OS, and Hardware experts across Apple. Your responsibilities will be dynamic, ranging from architecting core OS features to acting as a performance specialist for other teams. This includes defining and implementing critical system-level functionality, such as new systems to manage the process lifecycle, reclaim memory, or lead the transition to a 64-bit OS architecture.

Establish SW’s needs for future hardware, i.e. by modeling and projecting memory demand over the whole lifetime of a new SoC Engage in investigative and research-like projects to explore and prototype solutions for complex, open-ended problems. Diagnose and address functional and performance issues at the language, runtime, and kernel layers as well as in application and system daemons. Implement new software components, frameworks, and applications. Collaborate with cross-functional teams to define, design, and ship new features.

Minimum Qualifications 8+ years industry experience. Deep technical understanding and hands-on experience with software development and lifecycle management. Experience with low-level OS systems, i.e. kernel, Darwin or drivers. Deep experience with power and performance measurement and investigation techniques. Solid computer science fundamentals. Excellent communication and interpersonal skills for collaborating with a technical team.

Preferred Qualifications Experience defining and contributing to application or systems architecture. Ability to work with technology partners at all levels of the stack, from hardware, sensors, and firmware to frameworks and applications. Experience in additional technical areas, like Graphics, UI or networking. Strong problem-solving and debugging skills, especially with ambiguous or undefined problems.
