We are now looking for a Senior Signal & Power Integrity Engineer! NVIDIA has continuously reinvented itself over two decades. Our invention of the GPU in 1999 sparked the growth of the PC gaming market, redefined modern computer graphics, and revolutionized parallel computing. More recently, GPU deep learning ignited modern AI — the next era of computing. NVIDIA is a “learning machine” that constantly evolves by adapting to new opportunities that are hard to solve, that only we can tackle, and that matter to the world. This is our life’s work, to amplify human imagination and intelligence. This is a dynamic team working with state of the art, unique technology. If you are someone that loves a challenge, come join this diverse team and help move the needle! What you'll be doing: • Work on crafting creative Signal and Power Integrity solutions to complex system design problems. • System-level power integrity simulations of high-performance AI systems, graphic cards, and Tegra systems. • Work closely with VLSI power teams and package/board design teams to design, optimize, and model power delivery networks (PDN) including dies, packages, boards, and voltage regulators. • Package and board PDN guidelines creation, review, and post layout PI extractions. • Opportunity to work in a dynamic cross-functional role to optimize package, PCB, ASIC, mixed signal circuit. What we need to see: • MS/PhD in Electrical Engineering or equivalent experience. • 4+ years of industry experience. • Strong technical background in applied electromagnetics, transmission line theory, and signal processing is highly valued. • Experience in power integrity for core power or I/O power. • Strong understanding of how die/package/board decoupling impacts power supply noise across different frequency ranges. • Knowledge of on-die current di/dt control techniques such as dynamic clocking and throttling. • Familiarity with the SIMPLIS tool for regulator modeling; experience in modeling the behavior of on-die di/dt control techniques is highly preferred. • Hands-on experience with PowerSI, 3D modeling tools such as ANSYS HFSS/Q3D, 2.5D tools such as ANSYS SIwave (or similar), and 2D tools such as Ansys 2D Ways to stand out from the crowd: • Good understanding of how regulators work and expertise in regulator modeling. • Knowledge of package/board/decoupling capacitor technology & design. • Scripting for analysis automation #LI-Hybrid Your base salary will be determined based on your location, experience, and other objective job-related factors.
