Senior Staff PCB Layout Design Engineer Location: Santa Clara, CA (Hybrid/On-site)
About the Role As a Sr. Staff PCB Layout Design Engineer , you will be the lead architect of the physical medium that connects our breakthrough AI silicon to the world. At d-Matrix, our "Corsair" platforms push the boundaries of signal density and power delivery. You will own the layout of high-complexity, high-layer-count PCBAs (20+ layers), ensuring that 112G/224G SerDes signals remain pristine and that thousands of Amps are delivered across the board with minimal loss.
In this senior leadership role, you will also serve as the custodian of our Design Methodology , driving the automation, tooling, and rigorous constraint management processes that allow us to scale our hardware development with high precision and speed.
Key Responsibilities
Full-Cycle System Layout: Lead the layout for high-complexity AI accelerator cards (PCIe form factors) and massive system baseboards.
Constraint Management & Process: Architect and manage the Constraint Manager (CM) hierarchy within Cadence Allegro. You will define the "Source of Truth" for high-speed routing rules, physical spacings, and electrical constraints, ensuring they are consistently applied across all project phases.
Tooling & Automation: Drive productivity by developing or implementing automation scripts (SKILL, Python, or TCL) to streamline repetitive layout tasks, DRC checks, and report generation.
High-Speed Mastery: Execute layout for ultra-high-speed interfaces, including PCIe Gen5/6 , CXL , and custom die-to-die (D2D) interconnects.
Power Delivery Optimization: Work with Power Engineers to implement complex PDN strategies, including multi-phase VRM layouts and optimized decoupling capacitor placement for high-TDP ASICs.
Stack-up & Material Science: Drive the definition of PCB stack-ups, selecting advanced low-loss materials (e.g., Megtron 7/8) and managing hybrid build-ups.
DFx & Manufacturing: Act as the primary interface with PCB fabricators and CMs to ensure DFM, DFT, and DFA requirements are met for high-yield production.
Required Qualifications
Education: BS in Electrical/Electronic Engineering or equivalent practical experience.
Experience: 12+ years of experience in high-speed, high-density PCB layout for servers, networking, or AI accelerators.
Mastery of Constraints: Expert-level proficiency in Cadence Allegro Constraint Manager , including the setup of complex T-junctions, differential pair phase-tuning, and Z-axis delay matching.
Automation Skills: Proven ability to write and deploy SKILL scripts or utilize Allegro’s API to automate design audits and layout routines.
Technical Depth:
Deep understanding of high-speed routing (back-drilling, via-in-pad, and skip-vias).
Experience with HDI (High-Density Interconnect) and ELIC (Every Layer Interconnect).
Proven track record of successfully routing 112G SerDes and complex DDR5/HBM interfaces.
Preferred Skills
Experience establishing a Library Management System and standardized footprint/padstack creation processes.
Familiarity with PLM/PDM integration for managing layout releases and ECO (Engineering Change Order) workflows.
Knowledge of PCB warpage mitigation strategies for large-form-factor ASICs and MCMs.
The d-Matrix Advantage You aren't just a drafter; you are a hardware systems architect. At d-Matrix, you will have the autonomy to build the layout infrastructure from the ground up, implementing the automation and rigorous processes necessary to deliver the world's most advanced Digital In-Memory Computing platforms.
Equal Opportunity Employment Policy d-Matrix is proud to be an equal opportunity workplace and affirmative action employer. We’re committed to fostering an inclusive environment where everyone feels welcomed and empowered to do their best work. We hire the best talent for our teams, regardless of race, religion, color, age, disability, sex, gender identity, sexual orientation, ancestry, genetic information, marital status, national origin, political affiliation, or veteran status. Our focus is on hiring teammates with humble expertise, kindness, dedication and a willingness to embrace challenges and learn together every day.
