SoC Performance and QoS Validation Engineer

SummaryPosted: Role Number:200578000Do you love creating elegant solutions to highly complex challenges? Do you intrinsically see the importance in every detail? As part of our Silicon Technologies group, you’ll help design and manufacture our next-generation, high-performance, power-efficient processor, system-on-chip (SoC). You’ll ensure Apple products and services can seamlessly and efficiently handle the tasks that make them beloved by millions. Joining this group means you’ll be responsible for crafting and building the technology that fuels Apple’s devices. Together, you and your team will enable our customers to do all the things they love with their devices! Join a team of expert software engineers that translate architecture specifications and use case descriptions for new and emerging workloads including Machine Learning (ML) to test scenarios on Silicon on Apple designed SOCs.DescriptionYou will gain insights into the ground breaking SOC IP and chip-level architecture that powers Apple Products (iPhone/iPad/Macs/Watch/TV) You will help validate the block level and system level performance of various subsystems in the SoC, and the QoS architecture of the SoC You will collaborate with multi-functional teams including architecture, hardware design, and software teams to develop testplans, debug, and correlate silicon data. You will maintain and improve the internally developed Real Time Operating System (RTOS) that executes on the AP Clusters and IO Co-Processors, to enable QOS validation and to validate Power management features You will write low-level driver code in a RTOS to configure and run various sub-systems (e.g. display, cameras, video encoders/decoders, fabrics, power management) You will develop system software to validate the power management features of the SOC You will develop and maintain latency critical software to identify and root-cause complex performance/QoS issues You will help bringup prototypes and explore power and performance of bare metal workloads You will acquire valuable software skills writing a bare-metal RTOS, developing and debugging device drivers/RTOS using lldb/Xcode, and modeling real customer usecasesMinimum QualificationsBS + minimum of 3 years of experiencePreferred QualificationsExpert in C and C++, knowledge of assembly is desiredStrong understanding of ARM specification, computer architecture, system architecture, SoC architecture, and memory systemsKnowledge of Atomic operations, memory barriersExperienced with embedded systems programming (e.g. bare-metal, RTOS, kernel, driver programming)Experience with silicon bring-up and embedded software debugExperience with pipelining, bus architectures, and protocols is preferredExperienced with performance benchmarking and high-performance architecturesStrong understanding of common data structures, algorithms, Operating Systems concepts, and multi-threaded programmingSkilled at scripting – Python, bashExperience with some data analysis and data visualization tools is preferredPay & BenefitsAt Apple, base pay is one part of our total compensation package and is determined within a range.
