We are seeking a Senior uArch Exploration Engineer to join our CPU Performance team in Austin or Raleigh. In this role, you will focus on defining the microarchitecture for Arm’s next-generation Cortex-X and Neoverse CPUs. You will help shape CPU designs by building and analyzing performance models, studying workloads, and evaluating new ideas for performance, power, and efficiency. This is a highly collaborative role, working with CPU architects, designers, and partners to influence future CPU directions.
Job Responsibility:
Define and explore new CPU microarchitecture concepts for performance, power, and efficiency
Build and refine performance models (cycle-accurate and functional simulators)
Analyze workloads and performance sensitivities to guide design trade-offs
Collaborate with architects and design engineers to translate ideas into practical designs
Engage with partners to understand performance requirements and workload expectations
Present technical analysis and recommendations clearly across diverse audiences
Requirements:
BS/MS in Computer Science, Electrical Engineering, or Computer Engineering
5–10 years of experience in CPU microarchitecture development, performance modeling, or workload analysis
Strong understanding of CPU microarchitecture fundamentals and performance/power/area trade-offs
Hands-on experience with simulators (cycle-accurate, functional) and modeling infrastructure
Proficiency in C++ and Python
Strong analytical, problem-solving, and communication skills
Nice to have:
Experience with workload characterization and benchmarking
Familiarity with advanced software engineering practices and profiling tools
Exposure to customer or partner-facing technical discussions
