Staff GPU Shader RTL Architect & Microarchitecture Lead

Per International; San Diego (CA); On-site; USD 180,000 - 260,000; Full time

Job summary

Per International seeks a Staff/Senior Staff GPU Engineer specializing in Shader System RTL Design and Microarchitecture to shape next‑gen GPU IP. You will drive shader core pipelines, scheduling, and instruction dispatch, working across architecture, compiler, software drivers, and verification to meet ambitious performance and power goals.

Role emphasizes hands-on RTL coding in SystemVerilog/Verilog, deep GPU architecture knowledge, and collaboration with post-silicon teams to deliver scalable

Qualifications

• BS, MS, or PhD in Computer Science, Electrical Engineering, Computer Engineering, or related field, or equivalent practical experience.
• 8+ years for Staff level, or 10+ years for Senior Staff level, in RTL design, microarchitecture, or architecture for GPU/graphics/processor/AI accelerator/SoC subsystems.
• Strong hands-on experience with SystemVerilog, Verilog, VHDL, C/C++, and scripting languages such as Python, Perl, Tcl, or shell.
• Proven experience designing complex RTL blocks with understanding of timing, area, power, clocking, reset, CDC/RDC, low-power design, synthesis constraints.
• Solid understanding of computer architecture, GPU architecture, processor pipelines, parallel execution models, memory hierarchy, interconnects, and performance/power trade-offs.
• Experience with RTL quality flows including lint, CDC, reset analysis, synthesis, formal checks, assertions, waveform debug, and regression debug.
• Ability to work effectively with architecture, verification, physical design, software, compiler, performance, and post-silicon teams.

Responsibilities

• Define, develop, and own GPU shader subsystem microarchitecture specifications.
• Lead RTL design for shader-related blocks, including shader pipelines, instruction issue, operand collection, register files, dependency tracking, and pipeline control.
• Collaborate with architecture and compiler teams to translate ISA behavior, API requirements, shader workloads, and performance targets into efficient hardware designs.
• Analyze GPU workloads and performance data to improve occupancy, throughput, latency hiding, register pressure, and power efficiency.
• Support the full GPU IP lifecycle, including microarchitecture definition, RTL coding, lint/CDC/RDC cleanup, verification support, synthesis, timing closure, tape-out, bring-up, and post-silicon debug.
• Partner with verification teams on test plans, coverage, assertions, debug strategies, and directed-random test scenarios.
