Job Description

As Principal Engineer, System HW Design - SI/PI, you will be part of the Systems Hardware Engineering Team that designs, builds, brings-up, and productizes PCB boards for SiMa.ai. This showcases SiMa's MLSoC™ Machine Learning SoC across bring-up and debug, characterization, customer samples, and eventual production. In this role, you will define and drive SI/PI strategy across our entire MLSoC product line — spanning System-on-Module designs, PCIe add-in cards, chip-down BGA reference designs, and full development platforms. This is a significant technical contributor role that will define how signal and power integrity (SI/PI) is implemented across the hardware organization. Working with internal teams and external vendors, the role will guide PCB design, simulation,



and lab validation to ensure reliable high-speed signaling and power delivery across our hardware platforms.

Role & Responsibilities

• Define, document (including simulation reports and design decisions),own SI/PI architecture, design guidelines, review processes, and sign-off criteria across the full SiMa.ai product portfolio (SoM, PCIe HHHL card, chip-down BGA design, DevKit carrier, and future platforms).
• Serve as the technical specialist on high-speed interface margin closure: PCIe Gen5 (root complex, up to 32 GT/s/lane), MIPI CSI/DSI (C-PHY/D-PHY), USB 3.x/Type-C, 10 Gigabit Ethernet SerDes, and LPDDR memory channels
• Drive stack-up, impedance, and channel budget decisions across concurrent board programs, resolving trade-offs between cost, manufacturability, and signal margin at the product-line level
• Own power delivery network (PDN) architecture for high-transient-current AI accelerator silicon, setting design targets and review standards used across all boards
