GPU Performance Engineer, Platform Architecture
Develop high-performance C++ GPU simulators and architectural models supporting ray tracing, mesh shading, and AI workloads for iPhone, iPad, and Mac products.
About the role
This role involves developing and maintaining high-performance C++ models for GPU architectures used in iPhone, iPad, and Mac products. You will implement architectural features such as machine learning for AI, ray tracing, and mesh shading, while conducting performance analysis and model-to-RTL correlation.
What you'll do
- Code and debug performance and functional C++ models of GPU architectures.
- Implement hardware features including machine learning for AI, ray tracing, and mesh shading.
- Validate features and correlate simulation results against other models and RTL to ensure accuracy.
- Build and utilize data analysis tools to evaluate performance data generated by simulation models.
- Run performance experiments, analyze results, and propose architectural changes alongside architecture, design, compiler, and software teams.
What you'll need
- Bachelor’s degree in a relevant field.
- 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 hardware components such as processing cores, texturing units, caches, and memory hierarchies.
- 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.
