The CPU Cache Microarchitect/RTL Engineer role at Apple involves driving the architecture and development of multi-level cache subsystems for multi-processor systems. This position is part of Apple's Silicon Engineering Group, which focuses on designing high-performance, low power microprocessors for innovative products. The engineer will work on micro-architecture development, RTL design, and performance verification. A strong emphasis is placed on collaboration with multi-functional engineering teams to ensure successful design delivery.

• Minimum BS degree and 3+ years of relevant industry experience
• Experience with microprocessor architecture
• Experience with logic design principles with timing and power implications
• Experience in Verilog or VHDL
• Experience with simulators and waveform debugging processes
• Expertise in coherence protocols and interconnects, high performance design techniques, and memory subsystem management
• Understanding of low power microarchitecture techniques
• Understanding of high-performance techniques and trade-offs in CPU microarchitecture
• Experience in C or C++ programming
• Experience using an interpretive language such as Perl or Python

• Develop and specify micro-architecture from high-level exploration to detailed specifications
• Own the development, assessment, and refinement of RTL design targeting power, performance, area, and timing goals
• Support the verification team in developing test benches and conducting functional verification
• Explore high-performance strategies and verify that the RTL design meets performance targets
• Collaborate with multi-functional engineering teams to implement and verify physical design aspects
