Job description

The Performance Modeling Architect will lead the architectural definition and enhancement of next-generation CPU Cache Hierarchies and interconnects. This role focuses on creating scalable solutions that bridge the high-reliability needs of Automotive and the efficiency demands of Data Center systems. The architect will develop high-fidelity performance models to ensure optimal data movement across silicon. This position requires collaboration with various teams to drive architectural trade-offs and optimize performance.

Requirements

  • A Master’s or Ph.D. in Computer Engineering, Electrical Engineering, or Computer Science with a focus on architecture and 5+ years of experience.
  • Strong understanding of CPU microarchitecture, memory consistency models, and cache coherency protocols.
  • Proven experience in C++ or SystemC for cycle-accurate or functional modeling.
  • Proficiency in Python or similar scripting languages for processing large datasets and automating simulation sweeps.
  • Understanding of Network-on-Chip (NoC) topologies and arbitration logic.

Responsibilities

  • Develop and maintain high-fidelity, cycle-accurate performance models for coherent interconnects and shared caches.
  • Model and analyze performance bottlenecks across varying scales from automotive SoCs to data center architectures.
  • Evaluate the performance impact of different coherency protocols and snooping filters.
  • Run and analyze industry-standard benchmarks to drive architectural trade-offs.
  • Collaborate with build and verification teams to correlate performance models with silicon.

Benefits

  • Employees at NVIDIA are often offered comprehensive, day-one benefits—including medical, dental, and vision coverage with HSA support, life and disability insurance, an Employee Assistance Program, and a 401(k) with auto-enrollment. Many roles also have generous time off and holidays, donation matching (up to $10,000), and a wide menu of extras like FSAs, commuter benefits, legal and identity-theft protection, pet insurance, and wellness discounts. Optional programs can include student-loan and home-purchase support, plus family care resources and expert medical services.
