You"ll learn the ML accelerator domain on the job. ## Description AWS"s Trainium and Inferentia chips power the world"s largest machine learning clusters. Our team builds C++ models of these custom SoCs that RTL designers, verification engineers, and software teams depend on throughout the silicon development lifecycle. We"re looking for a modeling engineer to build and own models that directly impact how our chips are designed, verified, and brought to production. What you"ll do: * Develop and maintain high-fidelity functional model of AI/ML accelerator and its SoC subsystems, including compute engines, memory hierarchies, on-chip interconnects, and data paths - translating architecture specs and RTL behavior into accurate, testable C++ models * Validate model behavior against RTL simulations, emulation platforms, or silicon measurements; debug discrepancies and drive model-to-RTL correlation to high fidelity * Partner with design verification teams to integrate models into pre-silicon validation environments and catch architectural bugs early in the design cycle * Collaborate with architects/micro-architects, RTL design engineers, ML SW engineers, and compiler engineers to evaluate architecture and microarchitecture tradeoffs and help make hardware design decisions * Contribute to cycle-approximate performance model effort enabling architectural exploration ahead of RTL availability, early software development * Quantify system-level tradeoffs across compute, memory bandwidth, networking, and storage to influence reference architectures and long-term silicon strategy * Build and improve modeling infrastructure: simulation frameworks, regression suites, automated correlation checks, and coverage-driven validation flows * Develop modeling methodologies and tools that scale across multiple IP blocks and SoC generations, improving team efficiency and model reuse Why this role is interesting: * Your models are used to verify silicon before it"s built - bugs you catch save months of schedule and millions of dollars * You"ll work at the intersection of software engineering and chip design, with deep visibility into how custom ML accelerators are architected * As the team scales, there"s a clear path into architectural modeling - using your models to influence chip design decisions, not just validate them * Small team, high ownership, direct impact on AWS"s most strategic silicon programs
