SI​/PI Engineer

We are building Physics AI for hardware design. Our software platform helps hardware designers and physics simulation engineers explore, analyze, and optimize hardware systems, leveraging cutting-edge AI to deliver ultrafast, accurate physics intelligence within the realities of engineering design workflows.

Our first product bridges the gap between the accuracy & determinism of traditional simulation and the speed & scaling of AI, and is redefining how the world’s most advanced semiconductors are designed, verified, built, brought to market and integrated in complex systems.

As part of the Forward Deployment Sales team, you will play a key role in accelerating the adoption of Vinci’s software with leading engineering teams. You will work closely with prospective customers to demonstrate Vinci’s capabilities and show how the platform can significantly improve product design, thermal performance, time to market and reliability.

In this role, you will apply your power architecture, electromagnetics and transmission line theory to build and simulate models from real customer designs, validating Vinci's software and proving its value in production workflows. The work spans SI/PI analysis of high speed interfaces (HBMm DDR/LPDDR, PCIe, Ser Des, UCIe) and power delivery networks across the full chip-package-PCB stack and puts you in front of customers regularly for training and technical deep-dives.

You will work directly with customer engineering teams to understand their requirements, field technical questions, and articulate what Vinci's software can do. What you learn in those engagements feeds back into the roadmap, surfacing the needs and gaps that shape where the product goes next.

This is a hybrid role, with the expectation of working 3 days per week in our Palo Alto office for close collaboration with Sales, Product, and Engineering. The role includes moderate travel, primarily within the United States. Some infrequent international travel may be required for key customers and events in Asia and Europe.

• Engage with customer package and PCB design engineers during evaluations: set up simulations, run test cases, and turn SI/PI results into layout optimization recommendations.
• Assess system-level SI/PI performance and correlate Vinci results against industry-standard EM and circuit simulation tools.
• Work with the sales team on product demos, proof-of-concept evaluations, and technical deep-dives with prospective customers.
• Support onboarding and deployment with technical guidance, training, and troubleshooting through production use.
• Identify customer pain points in SI/PI workflows and work with product and engineering teams to improve capabilities.
• Deliver training sessions and workshops so customer teams can adopt and scale Vinci in their design flows.
• Represent Vinci at industry conferences and semiconductor events through live demos and technical engagement with prospects and partners.
• Track industry trends, emerging technologies, and best practices in SI/PI design methodologies and competing tools, so you can clearly explain what sets Vinci apart.

• Degree in Electrical Engineering or a related field, with a strong academic background in EM theory and transmission lines
• 5-10+ years of hands-on SI/PI analysis for high-speed interconnects in chip/package or system PCB design
• Experience with industry SI/PI modeling tool chains:
  Ansys HFSS/SIwave/Q2D, Keysight ADS, Cadence Sigrity, SPICE/Spectre, or similar
• Working knowledge of SI fundamentals for high-speed Ser Des and parallel interfaces, plus PI fundamentals: PDN impedance, decoupling, IR drop, and noise
• Scripting skills in Python, MATLAB, or Perl
• Experience in a…
