If you want to build infrastructure that fundamentally changes what the world can accomplish with AI, come join us! About the position  We are looking for a Senior Signal Integrity (SI) and Power Integrity (PI) Engineer to own end-to-end electrical link performance across our high-speed interconnects - from architecture and pre-silicon modeling through silicon bring-up, validation, and high-volume manufacturing (HVM). This is a hands-on technical role for someone who has taken multiple products from concept to production and knows what breaks (and why) once real volume hits the line. Responsibilities  • Own signal integrity and power integrity analysis for end-to-end high-speed links, including package, connector, PCB, and cable interconnects • Drive SI/PI closure for high-speed SerDes interfaces (112G/224G-class), PCIe (Gen5/Gen6+), and parallel/single-ended interfaces such as DDR/LPDDR memory and chip-to-chip links • Perform pre-silicon channel modeling, budgeting, and margin analysis using COM (Channel Operating Margin), IBIS-AMI, and statistical eye methodologies • Build and correlate 3D/2.5D EM models (HFSS, PowerSI) against lab measurement (VNA, TDR, BERT, scope) to validate channel and package performance • Perform system-level power delivery network (PDN) analysis, decoupling strategy, and power/SI co-design across chip, package, and board • Use ADS and MATLAB for circuit-level simulation, link budget analysis, and custom post-processing/automation of simulation and lab data • Support silicon bring-up, debug, and characterization in the lab; root-cause SI/PI-related failures and drive corrective actions • Partner with ASIC, package, PCB layout, and mechanical teams to define design rules, stackups, routing guidelines, and connector/material selection • Lead products through DVT/PVT and into high-volume manufacturing, including establishing test limits, correlating ATE/system-level test data to simulation, and resolving field/yield issues tied to SI/PI margin • Contribute to internal methodology, tooling, and design guideline development. Requirements • 10+ years of hands-on SI/PI engineering experience in the semiconductor, systems, or networking hardware industry • Demonstrated experience across the full product lifecycle — architecture through production and sustained high-volume manufacturing — not just simulation-only roles • Deep working knowledge of high-speed SerDes signaling, including 224G (or comparable leading-edge) electrical interfaces, and PCIe link architecture • Solid experience with parallel/source-synchronous interfaces such as DDR/memory buses and chip-to-chip interconnects • Proficiency with COM-based analysis and IBIS-AMI modeling for channel compliance and margin assessment • Strong command of industry-standard tools: Ansys HFSS, Ansys PowerSI (or equivalent 2.5D/3D field solvers), Keysight ADS, and MATLAB • Hands-on proficiency with SI/PI lab testing and validation equipment, including Vector Network Analyzers (VNA) for S-parameter extraction, TDR/TDT for impedance and discontinuity characterization, and oscilloscopes for eye diagram, jitter, and signal quality measurement • Familiarity with power integrity fundamentals — PDN impedance analysis, decap strategy, DC/AC drop, and chip-package-board co-design • Experience working with cross-functional teams (ASIC design, package engineering, PCB layout, test/ATE, manufacturing) to drive designs to closure • Excellent written and verbal communication skills; able to clearly present technical risk and trade-offs to both engineering and program stakeholders Preferred Qualifications  • Experience with additional high-speed standards (CXL, Ethernet SerDes) • Scripting/automation experience (Python) for simulation flow automation or data analysis • Experience with connector, cable, or optical module electrical characterization • Familiarity with signal/power co-simulation and chip-package-system (CPS) modeling flows • Exposure to compliance testing and industry standards bodies (PCI-SIG, OIF-CEI, JEDEC) We seek smart, curious, self-driven individuals who enjoy creative problem-solving and continuous learning. Even if you don't meet all requirements, we'd love to hear from you if you have the mindset to tackle complex challenges. Majestic Labs is an equal opportunity employer deeply committed to diversity of background and thought. If you are ready to dare greatly, learn from mistakes, engage in vigorous debates, and help create a step-function shift in human technical capability, we want to meet you!

We are looking for 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 creativity and intelligence! We work closely with NVIDIA sites in USA and China and have access to extensive knowledge, technologies and tools. Taking the products from concepting, through design, implementation, verification and release to customers. If you thrive working with highly skilled people that enjoy reaching challenging goals then NVIDIA might be the perfect workplace for you. 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: • Design low-speed I/O channels such as clock circuits, DDR/memories and other sensitive signals. • Design layout guidelines for our packages and PCBs (for switches, adapters and electro-optical modules). • Design package/board/system SI/PI design activities, including PCB stack-up/material selection, design guide implementation, layout review and post-layout analysis. • Work closely with Architecture, ASIC, Mixed Signal, Package, and PCB design teams to design and ensure system SI/PI performance meets expectation. • Simulate passive and active elements in 3D and 2D simulation tools. • Measure systems in the lab using Network Analyzer, TDR and scope. • Work in an intense environment and control multi-discipline expertise What we need to see: • B.Sc. in Electrical Engineering (or equivalent experience) • 5+ years of experience • Expert with low-speed I/O simulations and design concepts including clock circuits, DDR/memories , transmitter & receiver design and equalization schemes. • Expert level proficiency with time domain analysis and tools. • Excellent understanding in electromagnetic waves including transmission line theory and via properties. • High level proficiency with electromagnetic tools (such as Ansys EM, CST, etc.) • Experience in Lab measurements including VNA & TDR. • Ability to work in an intense environment and control multi-discipline expertise.
