About the Company



Our client is a well-funded, venture-backed startup developing next-generation GPU technology. The company is in a growth stage with significant capital backing and is building a world-class engineering team to design high-performance, scalable GPU architectures from the ground up.


This is a rare opportunity to join at a foundational stage and directly shape the direction of cutting-edge silicon.



About the Role



We are seeking an experienced GPU Architect/Designer with strong expertise in shader core architecture and SIMT (Single Instruction Multiple Threads) execution models. This role involves defining next-generation GPU microarchitecture, optimizing throughput and efficiency, and driving scalable, high-performance parallel compute solutions. The ideal candidate will have deep knowledge of GPU shader pipelines, thread scheduling, memory hierarchy, and parallel execution models, with experience translating architectural concepts into high-quality RTL implementations.



Responsibilities



Architecture & Microarchitecture

  • Define and evolve GPU shader core architecture, including SIMT execution units and pipeline design.
  • Design warp/wavefront scheduling, thread dispatch, and execution models.
  • 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



  • Education: Bachelor's, Master's, or PhD in Computer Engineering, Electrical Engineering, or Computer Science.
  • 10+ years of experience in GPU, CPU, or parallel processor architecture.


Required Skills



Strong experience with:

  • SIMT / SIMD architectures
  • Shader core design
  • Thread scheduling
  • Pipeline microarchitecture
  • Memory hierarchy design


Proficiency in:

  • SystemVerilog or Verilog
  • Microarchitecture specification development
  • Performance modeling tools
  • RTL-level debugging


Deep understanding of:

  • Parallel computing models
  • GPU execution models
  • Pipeline hazard handling
  • Synchronization primitives


Pay range and compensation package



175,000 - 250,000 USD + Meaningful Equity



Equal Opportunity Statement



We are committed to diversity and inclusivity in our hiring practices.
