Role Overview
We are seeking an Architecture Performance Engineer to join our CPU Performance team in Austin or Raleigh. In this role, you will focus on ensuring new Architecture extensions are performant for next-generation Arm CPUs. You will work closely with architects and designers to analyze performance trade-offs, build models, and validate architectural concepts prior to implementation. This position is ideal for candidates who enjoy bridging the gap between architecture definition and microarchitecture realization.
Responsibilities
As part of the CPU Performance – Architecture Performance team, you will be accountable for:
· Architecture Feature Evaluation
o Model and evaluate the performance impact of proposed architectural extensions.
o Develop cycle-approximate and high-level performance models for architectural features.
o Perform sensitivity studies to assess benefits and trade-offs.
· Correlation & Validation
o Correlate performance projections from cycle-approximate models with RTL implementations to ensure accuracy.
o Identify gaps and propose refinements in modeling and methodology.
· Workload & Benchmark Development
o Design and implement microbenchmarks to evaluate architectural features.
o Analyze workload performance to understand the impact of new instructions or
extensions.
· Collaboration & Support
o Work closely with architecture, microarchitecture, design, compiler and software teams to guide decision-making.
o Communicate results and insights to partners and internal stakeholders.
Required Skills and Qualifications
· BS or MS in Computer Science, Electrical Engineering, or Computer Engineering.
· 5+ years of experience in CPU architecture, performance modeling, or related areas.
· Strong understanding of CPU architecture and microarchitecture fundamentals.
· Hands-on experience with performance modeling (functional, statistical, or cycle-approximate).
· Proficiency in C++ and Python for model development and data analysis.
· Strong analytical and problem-solving skills with attention to detail.
· Effective communication skills, with the ability to present technical results clearly.
Preferred Qualifications
· Experience correlating architectural/performance models with RTL.
· Knowledge of benchmarking methodologies and workload characterization.
· Familiarity with Arm architecture or other modern CPU ISAs.
· Exposure to power/performance/area (PPA) trade-off analysis.
· Experience using functional models to develop software prior to the availability of hardware.
· Exposure to compiler design, code generation, and software optimization techniques.
At Arm, you will thrive in a highly stimulating and collaborative environment. You will be encouraged to share your ideas and experiences, while learning new skills from the best engineers in the world.
