About The Position

Samsung, a world leader in advanced semiconductor technology, is founded on a simple philosophy – the endless pursuit of excellence will create a better world for all. At Samsung Austin Research and Development Center (SARC) and Advanced Computing Lab (ACL), we are building a center of excellence for Intellectual Property (IP) that is applied to high-performance computing devices (mobile, automotive, and other custom market segments) consumed by millions of people around the world. Come build with us!
We are seeking a highly experienced CPU Micro-Architect to join our team at Samsung SARC/ACL. As a CPU Micro-Architect, you will be responsible for designing and optimizing high-performance CPU microarchitectures for mobile, data center, and other applications. You will develop and implement innovative microarchitecture techniques, analyze performance, and optimize SoC designs.

Requirements

• 15+ years of experience with a Bachelor’s Degree in Computer Science/Engineering, or 13+ years of experience with a Master’s Degree, or 11+ years of experience with a Ph.D.
• Strong fundamentals in key computer architecture concepts, such as virtual aliasing, pipelining, cache hierarchies, coherency, memory subsystem, etc.
• Deep knowledge in high-performance OoO CPU microarchitecture and SOTA optimization techniques in key areas such as pipelining, interlock, caching, prefetching, branch prediction, cache/TLB hierarchy and their PPA implications
• Ability to perform quantitative analysis of key mobile benchmarks such as Geekbench6 and SPECCPU17 and correlation with HW PMU stats (cache misses, TLB misses, pipeline stalls, etc.)
• Extensive programming experience with RTL code (Verilog or SV), and writing C/C++/Python scripts, for performance evaluation of uarch techniques
• Working experience with top-down microarchitecture analysis method (based on PMU stats)
• Ability to extract and assess key uarch ideas in open literature
• Strong communication and collaboration skills, with the ability to work effectively in a cross-functional team environment

Nice To Haves

• Actual RTL implementation experience on high-performance OoO processors
