Senior/Principal GPU Architect & Modeling Lead

PER International; California (MO); On-site; USD 170,000 - 260,000; Full time

Job summary

PER International is seeking a Senior/Principal Engineer to define and develop next‑generation GPU architectures for SoCs in a highly technical, individual‑contributor role. You will build models, simulate performance and power, and guide architectural trade‑offs across RTL, DV, software and performance teams.

You will analyze workloads from games to AI kernels, drive optimization opportunities, and influence roadmap decisions for future GPU products with a focus on efficiency and scalability.

Qualifications

• BS/MS or higher in Computer Science, Electrical/Computer Engineering or a closely related field.
• 8+ years of experience in GPU, graphics, high‑performance compute, AI accelerator, or related architecture/modeling areas.
• Deep understanding of modern GPU architecture and pipeline (graphics and/or compute).
• Strong experience with performance and/or cycle‑accurate modeling, simulation frameworks, or architectural exploration for complex SoCs or accelerators.
• Solid understanding of graphics and compute APIs such as Vulkan, OpenGL, DirectX and/or GPU compute frameworks (e.g., OpenCL, CUDA, Metal).
• Proficiency in at least one modeling or implementation language (e.g., C/C++, SystemC, Python).
• Experience with performance analysis tools, profiling methodologies and workload characterization.

Responsibilities

• Define and develop best‑in‑class GPU architecture and performance/power models for next‑generation SoCs.
• Build and maintain cycle‑accurate / performance / functional models of GPU subsystems (shader cores, fixed‑function units, memory hierarchy, interconnect).
• Use modeling and profiling to explore architectural trade‑offs (performance, power, area) and guide micro‑architecture decisions.
• Analyze workloads (games, graphics benchmarks, GPU compute, AI/ML kernels) using simulation and hardware profiling to identify bottlenecks and optimization opportunities.
• Collaborate with RTL, DV, software/driver, and performance teams to ensure architectural intent is implemented, verified and tuned.
• Provide architectural input to compiler/driver/runtime teams to maximize GPU hardware utilization through software optimizations.
• Develop methodologies, tools and automation flows for GPU performance estimation, capacity planning and regression analysis.
• Lead debug and root‑cause analysis of performance, power and bandwidth issues observed in models, emulation and silicon.
• Drive cross‑team technical discussions, present modeling results and architectural proposals, and influence roadmap decisions.
