Company

hirify.global's Trainium and Inferentia chips power the world's largest machine learning clusters.

What you will do

• Build and own models of SoC subsystems, translating architecture specs and RTL behavior into accurate, testable C++ models.
• Work directly with RTL design and verification teams to validate model behavior against RTL and debug discrepancies.
• Develop model-based test infrastructure, including regression suites and RTL correlation checks.
• Contribute to performance modeling efforts, building cycle-approximate models to evaluate design trade-offs.
• Improve modeling methodology and infrastructure for model structure, integration, and testing.
• Collaborate with chip architects to understand upcoming designs and plan modeling work.

Requirements

• 6+ years of full software development life cycle experience.
• 6+ years of experience 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.
• Experience as a mentor, tech lead or leading an engineering team.

Nice to have

• Experience working with DV teams or integrating models into verification flows.
• Experience correlating functional models against RTL simulation, emulation, or silicon.
• Experience developing and calibrating performance models for custom silicon.
• Experience with SystemC, TLM, or cycle-approximate modeling methodologies.
• Experience building regression and CI frameworks for model validation.
• Familiarity with Modern C++ (20 and beyond).
• Experience with multi-threaded or distributed simulation.
• ML accelerator architecture knowledge (a plus, not required).
