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 Solid 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.
