Job summary

Annapurna Labs (U.S.) Inc. in Cupertino/Austin seeks a modeling engineer to build and own high-fidelity C++ models of AI/ML accelerators and related SoCs.

You will collaborate with RTL, DV, and software teams to ensure model accuracy, integration, and scalable validation across IP blocks and generations. You will drive architecture discussions, calibrate models against RTL/silicon, and contribute to performance-modeling efforts for early software development.

Qualifications

• 6+ years of full software development life cycle experience including standards, reviews, source control, build, test, and operations.
• Experience as a mentor, tech lead, or leading an engineering team.
• 6+ years writing functional or performance models of hardware (SoCs, ASICs, GPUs, CPUs, IP blocks).
• Experience programming in C++, using advanced language features.
• Knowledge of SoC, CPU, GPU, and/or ASIC architecture and micro-architecture.

Responsibilities

• Develop and maintain high-fidelity functional models of AI/ML accelerators and its SoC subsystems in C++.
• Validate model behavior against RTL simulations, emulation platforms, or silicon measurements; debug discrepancies.
• Partner with design verification teams to integrate models into pre-silicon validation environments.
• Collaborate with architects/micro-architects, RTL design engineers, ML SW engineers, and compiler engineers to evaluate architecture tradeoffs.
• Contribute to cycle-approximate performance modeling for architectural exploration ahead of RTL availability.
• Quantify system-level tradeoffs across compute, memory bandwidth, networking, and storage to influence reference architectures.
• 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.
