## Description

As a Staff CPU Architecture & Performance Engineer, you will shape the architecture and performance direction of next-generation CPU architectures. You will identify opportunities across emerging workloads, develop and refine performance models, evaluate system-level architectural trade-offs, and drive new microarchitectural concepts from research to implementation. You will work closely with RTL design teams to translate architectural concepts into implementable designs, guide key technical decisions, and validate their impact from modeling through silicon. The role offers broad ownership across architectural domains, with the opportunity to define new research directions, influence CPU architecture strategy, and drive ideas that can deliver meaningful performance gains in real hardware.

 * Propose new architecture ideas and take ownership of one or more microarchitectural domains, including front-end, mid-end, and back-end
 * Use AI-driven design methodologies to rapidly implement architectural ideas and validate them on real silicon
 * Build, extend, and validate performance models and architectural simulators
 * Perform CPI/IPC analysis and identify root causes of performance bottlenecks
 * Evaluate microarchitectural features and optimizations using trace-driven, analytical, and cycle-accurate models
 * Characterize workloads and benchmarks, including SPEC, server, client, AI/ML, agentic AI, and internal traces
 * Translate performance analysis and modeling results into architectural direction and design decisions
 * Drive research leading to patents and technical publications, Give Back With a charitable giving match and frequent opportunities to get involved, we take an active role in supporting the community.
Enjoy Time Away You'll start with 4+ weeks of paid time off a year, plus holidays and sick leave, to rest and recharge.
Care for Family Whatever family means to you, we want to support you along the way-including a stipend for fertility care or adoption, medical travel support, and virtual vet care for your fur babies.
Prioritize Emotional Wellness With on-demand apps and free confidential therapy sessions, you'll have support no matter where you are.
Stay Fit Eating well and being active are important parts of a healthy life. Our onsite Caf and gym, plus virtual classes, make it easier.
Embrace Flexibility Benefits are best when you have the space to use them. That's why we facilitate a flexible environment so you can find the right balance for you., At Samsung Semiconductor, we use Artificial Intelligence (AI) tools in the recruitment process to enhance efficiency. However, AI is used as a support tool, not a final decision-maker. All hiring decisions are made by our human recruiting team and hiring managers to ensure every candidate is evaluated fairly and holistically.
