CPU Micro-architect

Position Summary

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 consumed by millions of people around the world. Come build with us!

Role and Responsibilities

We are seeking a talented CPU Micro-architect to join our team, where you will play a pivotal part in shaping next-generation processors for AI, high-performance computing, and edge devices. In this role, you will be responsible for exploring new features and optimizing the microarchitecture of high performance OoO CPU cores. You’ll collaborate with cross-functional teams and external partners to push the boundaries of processor design.

• Improve the benchmarks and real-use-case performance (IPC, power/area efficiency) of a state of the art (SOTA) OoO CPU core, covering all aspects of the micro-architecture, including core pipelines, branch prediction, prefetching, and cache/TLB hierarchy.
• Work with the performance simulation team to model the microarchitecture of the SOTA core.
• Correlate simulation results against silicon measurement data, and perform thorough root cause analysis and debugging to identify, diagnose, and rectify any discrepancies, ensuring model accuracy and reliability.
• Explore new features and ISA extensions (e.g., vector extensions, memory safety features, security enhancements, etc.) to drive performance enhancements, optimizing efficiency, reliability, and protection.
• Identify and resolve performance bottlenecks through modeling and prototyping.
• Develop performance models (as needed) and micro testbenches to improve and validate key performance features in the CPUs.
• Collaborate with cross-functional teams and external partners to ensure seamless integration of designs.

Skills and Qualifications

• 10+ years of experience with a Bachelor’s Degree in Computer Science/Engineering, or 8+ years of experience with a Master’s Degree, or 6+ years of experience with a Ph.D.
• Extensive background in CPU microarchitecture design, with a strong understanding of computer architecture principles, including pipelining, superscalar design, cache hierarchies, coherency, and multi-core systems.
• Strong experience in performance analysis, modeling, and optimization, as well as common mobile benchmarks like GB6 and SpecInt17, and real use cases such as games and web browsing.
• Familiarity with Arm ISA (Armv8/v9) and extensions, or equivalent ISAs (x86 and RISC-V), and their impact on microarchitecture.
• Proficiency in reading – and writing as needed – hardware description languages (Verilog/SV) and programming languages (C++, Python) for modeling and simulation.
• Ability to correlate simulation performance results against hardware performance metrics (cache misses, TLB misses, pipeline stalls) to ensure optimal performance.
• Excellent problem-solving skills and the ability to work in a collaborative, interdisciplinary environment.

Our Team

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.

Total Rewards

At Samsung – SARC/ACL, base pay is one part of our total compensation package and is determined within a range. This provides the opportunity to progress as you grow and develop within a role. The base pay range for this role is between $151,000 and $251,800.
