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. The System IP & SoC Architecture team at SARC/ACL designs proprietary coherent interconnects and memory controllers that power Exynos SoCs for Samsung's premium consumer devices. We play a critical role in shaping the technology roadmap, delivering scalable, performance- and power-optimized IP solutions that support advanced system modeling and real-world applications such as gaming and computational photography. With scalability and efficiency at the core of our designs, our IP integrates seamlessly into complex semiconductor products, enabling cutting-edge memory subsystem capabilities across diverse market segments. Joining our team means collaborating alongside talented engineers from diverse technical backgrounds across a global organization. You'll have the opportunity to build next-generation technologies, broaden your expertise, and solve impactful challenges in a supportive environment built on collaboration, continuous learning, and growth.
