Responsibilities
You are passionate about contributing to the design and execution of advanced performance modeling and analysis for GPU pipelines—including shader-level analysis, pipeline optimization, system-level characterization, and architectural prototyping
You enjoy learning about building and refining models and tools using C/C++, Python, and cycle-approximate frameworks to analyze and validate key metrics (such as latency, throughput, and power consumption), developing benchmarks, identifying bottlenecks, and proposing data-driven optimizations
You ensure design excellence and correctness through prototyping, model-to-RTL correlation, and deep-dive validation—including simulation, waveform analysis using tools like Synopsys Verdi, functional debug, and performance verification against required specifications
You proactively seek cross-functional collaboration with global teams, clearly communicate architecture proposals to diverse audiences, and exercising data-driven decision making to ensure seamless integration of the GPU into the overall system
You take initiatives on moderate-to-complex projects and help advance best practices, methodologies by staying ahead of industry trends and emerging technologies
