Company

hirify.global is a multinational technology company focusing on e-commerce, cloud computing, online advertising, digital streaming, and artificial intelligence.

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, 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.

Requirements

• 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.
• Are comfortable working with architectural / design specifications or reference implementations and translating them into C++ or SystemC models.
• Understand verification concepts and have worked with DV teams or in pre-silicon validation environments.
• Care about model fidelity and have experience correlating models against RTL or silicon.

Nice to have

• 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.
