GPU Performance Engineer, Platform Architecture
This role focuses on developing high-performance C++ GPU simulators to evaluate ray tracing, mesh shading, and machine learning features for iPhone, iPad, and Mac hardware.
About the role
This role joins the Platform Architecture GPU Modeling Team to develop and refine GPU simulators for research, performance analysis, and architectural tuning across iPhone, iPad, and Mac hardware. Responsibilities center on building and maintaining high-performance C++ models to evaluate hardware features such as machine learning for AI, ray tracing, and mesh shading.
What you'll do
- Code and debug performance and functional models of GPUs in C++.
- Implement hardware features including machine learning for AI, ray tracing, and mesh shading within the simulation environment.
- Validate model accuracy, conduct feature validation, and correlate simulator results against other models and RTL.
- Develop and utilize tools to analyze data generated by GPU performance models.
- Collaborate with architects, modeling engineers, compiler engineers, and software teams to run performance experiments, evaluate feature feasibility, and propose architectural changes.
What you'll need
- Bachelor’s degree in a relevant technical field.
- Demonstrated experience writing and debugging C++ code.
- Experience with scripting languages such as Python or Ruby.
Nice to have
- 10+ years of experience modeling GPUs, CPUs, or similar architectures.
- MS or PhD degree in a related field.
- Experience coding components such as processing cores, texturing units, caches, and memory hierarchies.
- Deep understanding of GPU/CPU architectures.
- Experience debugging performance issues and correlating multiple models.
- Understanding of data analysis tools such as Tableau, pandas, Excel, or matplotlib.
- Experience working with machine learning and/or graphics applications, games, or benchmarks.

How we counted: 486 open SoC/Chip Architecture (SOC Architecture) roles from 67 employers tracked in the SemiconductorJobs index, counted 11 Nov 2026. Specialty figures count only roles carrying this exact specialty label, so an employer's related work in neighbouring specialties is not included there, and is counted in the wider Digital Design & Verification family row. Days are counted from when our index first saw each posting, not from the employer's original posting date.
