Pre-Silicon SoC Modeling Engineer, Annapurna Labs Machine Learning Accelerators, AWS

Amazon's Annapurna Labs is focused on building advanced machine learning accelerators like Trainium and Inferentia. The Pre-Silicon SoC Modeling Engineer will develop C++ models of custom SoCs, collaborating with design and verification teams to ensure model accuracy and support pre-silicon verification flows.

What you'll 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, debug discrepancies, and support pre-silicon verification flows
• Develop model-based test infrastructure: regression suites, RTL correlation checks, and coverage-driven testing
• Contribute to performance modeling efforts — building cycle-approximate models that help architects evaluate design trade-offs before RTL exists
• Improve modeling methodology and infrastructure: how models are structured, integrated, tested, and released to DV and architecture teams
• Collaborate with chip architects to understand upcoming designs and plan modeling work ahead of RTL availability

What they're looking for:

• Experience programming languages such as C/C++, Python, Java or Perl
• 2+ years writing functional or performance models of hardware (SoCs, ASICs, GPUs, CPUs, IP blocks)
• Familiarity with SoC, CPU, GPU, and/or ASIC architecture and micro-architecture
• 2+ years of full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations experience
• Experience working with DV teams or integrating models into verification flows
• Experience with SystemC or TLM-based modeling
• Experience correlating functional models against RTL simulation or emulation
• Experience developing or calibrating performance models
• Familiarity with Modern C++ (20 and beyond)
• Experience with PyTest, GoogleTest, or similar test frameworks
• Experience with multi-threaded simulation

Benefits:

• Health insurance (medical, dental, vision, prescription, Basic Life & AD&D insurance and option for Supplemental life plans, EAP, Mental Health Support, Medical Advice Line, Flexible Spending Accounts, Adoption and Surrogacy Reimbursement coverage)
• 401(k) matching
• Paid time off
• Parental leave
