  • Architect SIMT execution pipelines, including ALU pipelines, vector units, and control flow units.
  • Define thread divergence handling, reconvergence strategies, and branch control mechanisms.
  • Develop scalable shader architectures supporting high thread-level parallelism.
  • Collaborate on ISA definitions related to shader and compute workloads.
  • Analyze shader workloads and identify performance bottlenecks.
  • Optimize GPU execution efficiency across diverse workloads including compute shaders, AI/ML kernels, and high-performance parallel workloads.
  • Drive performance-per-watt and area efficiency improvements.
• Memory & Interconnect
  • Define GPU memory subsystem interactions including register files, shared/local memory, L1/L2 cache hierarchy, and memory coalescing mechanisms.
  • Optimize memory access scheduling and bandwidth utilization.
  • Collaborate on interconnect and memory fabric architecture.
• RTL & Design
  • Translate architectural specifications into microarchitecture definitions.
  • Implement shader pipeline logic in SystemVerilog.
• Verification & Validation
  • Define architectural test plans and validation strategies.
  • Develop directed tests, constrained-random tests, and performance validation frameworks.
  • Analyze simulation and silicon results to drive design improvements.

Qualifications
