Company

hirify.global Web Services develops Trainium and Inferentia custom machine learning accelerator chips and the software and validation systems that support them.

What you will do

• Develop and maintain high-fidelity C++ functional models of AI/ML accelerators and SoC subsystems, including compute engines, memory hierarchies, interconnects, and data paths.
• Validate models against RTL simulations, emulation platforms, and silicon measurements, debugging discrepancies and improving model-to-RTL correlation.
• Integrate models into pre-silicon verification environments and help identify architectural bugs early.
• Collaborate with architects, micro-architects, RTL designers, ML software engineers, and compiler engineers on hardware design and microarchitecture decisions.
• Build cycle-approximate performance models to support architectural exploration and early software development.
• Develop scalable simulation frameworks, regression suites, automated correlation checks, coverage-driven validation flows, and reusable modeling methodologies.

Requirements

• 2+ years of experience writing functional or performance models of hardware such as SoCs, ASICs, GPUs, CPUs, or IP blocks.
• Programming experience with C/C++, Python, Java, or Perl.
• Familiarity with SoC, CPU, GPU, and/or ASIC architecture and microarchitecture.
• Experience working with architectural specifications or reference implementations and translating them into software or SystemC models.
• Understanding of verification concepts and experience with pre-silicon validation environments or design verification teams.
• Ability to work in Cupertino, California, or Austin, Texas, USA.

Nice to have

• Experience with SystemC or TLM-based modeling.
• Experience correlating functional models against RTL simulation or emulation.
• Experience developing or calibrating performance models.
• Modern C++ experience, including C++20 or later, and experience with PyTest, GoogleTest, or similar frameworks.
• Experience with multi-threaded simulation and full software development lifecycle practices.

Culture & Benefits

• Small, high-ownership team working on strategic AWS silicon programs.
• Opportunity to expand into architectural performance modeling and influence chip design decisions.
• Health, dental, vision, prescription, life, and AD&D insurance options.
• 401(k) matching, paid time off, parental leave, flexible spending accounts, and adoption and surrogacy reimbursement.
• Disability accommodations are available during the application and hiring process.
