We are building a high-impact team at the forefront of architectural innovation, and we're looking for a Senior Modeling Architect to be a key contributor. In this role, you'll develop functional models and simulators to explore, validate, and influence the architecture of NVIDIA's next-generation switches.You'll work at the crossroads of hardware architecture and software, building the models that architects and design teams rely on to make decisions — shaping cutting-edge networking systems from the ground up in a fast-paced, exploratory environment.What you'll be doing:Develop functional models and simulators of switch hardware blocks and subsystems.Build simulation infrastructure and toolchains for exploring and evaluating new hardware designs.Define modeling strategy, coverage, and methodology for new switch architectures.Work autonomously to define, design, and drive modeling features end to end.Collaborate across architecture, design, and verification teams to refine system-level behavior and define new methodologies.Take technical ownership and demonstrate natural leadership within the team and across groups.What we need to see:BSc or MSc in Electrical Engineering, Computer Engineering, Computer Science, or equivalent experience.10+ years in chip design, verification/validation, RTL simulation, firmware, or embedded software — with real, hands-on experience.Intimate knowledge of chip design and verification flows.Strong understanding of SW–HW flows and system integration across diverse technology components.Strong analytical thinking, debugging, problem-solving, and communication skills, written and verbal.Proven ability to work independently and drive ideas from concept to execution.Ways to stand out from the crowd:A background in validation or verification, looking to move closer to software and modeling — this role is a natural next step, and you'll grow your modeling and software skills as you go.Deep, hands-on experience with networking protocols — one of the strongest differentiators for this role.Experience with UVM or other verification methodologies.Familiarity with modern C++ and object-oriented design (a real plus, but something you can grow into here).Experience with SystemC, TLM, or other hardware modeling frameworks.NVIDIA is widely considered to be one of the technology world's most desirable employers. We have some of the most forward-thinking people in the world working for us. Are you a creative and autonomous engineer who loves a challenge? Are you ready to become the engineer you always wanted to be? Come and be part of the best architecture team in the industry!
