Fabric Modeling and Analysis Engineer- Scale Up Fabric Role Overview Astera Labs is powering the connectivity behind rack-scale AI, and our Scorpio Scale-Up Fabric is central to how tomorrow’s GPU clusters scale. As a Fabric Modeling and Analysis Engineer, you will own the performance models that shape this fabric — quantifying bandwidth, latency, and throughput ceilings, and predicting how Scorpio hardware behaves under real AI/ML workloads long before silicon exists. This is a high-impact role for an engineer who thrives where architecture, performance analysis, and software converge. Your models will shape the next generate products and enable informed architectural decisions ahead of tape-out, surface bottlenecks that only appear at scale, and translate directly into roadmap and IP decisions. As Astera Labs continues its hyper-growth, you’ll be the internal authority on fabric modeling. Key Responsibilities Simulation Infrastructure & Model Correlation Design, implement, and maintain features in AI/ML system simulators and fabric models, extending support for collective communication, transport, topology, congestion, routing, buffering, scheduling, and traffic management Improv …truncated… reports…
