Principal Hardware Design Engineer

About

At d-matrix, we are redefining the architecture of AI compute. As a Principal Hardware Design Engineer, you will be a cornerstone of our hardware organization, leading the development of world-class platforms for our silicon-integrated AI accelerators. You aren’t just “designing boards”; you are architecting the physical foundation that allows our Chiplet-based NPU (Neural Processing Unit) to solve the industry’s most massive LLM inference challenges.

Responsibilities

• Architectural Leadership: Lead the end-to-end hardware development lifecycle for complex, high-performance AI accelerator PCIe cards and chassis platforms
• Detailed Electrical Design: Own schematic capture, component selection, and rigorous BOM management for multi-rail, high-power designs
• High-Speed Design: Architect and oversee the layout of ultra-high-speed interfaces, including PCIe Gen5/6, CXL, and custom chiplet-to-chiplet interconnects
• Power Delivery (PDN): Design robust power delivery networks capable of handling high-current transients and low-voltage rails characteristic of advanced AI silicon
• Cross-Functional Collaboration: Partner closely with Silicon, Signal Integrity (SI/PI), Thermal, and Mechanical teams to ensure seamless integration and performance
• DFx & Manufacturing: Drive Design for Excellence (DFM, DFT, DFA) to ensure high-yield production and long-term reliability in data center environments
• Mentorship: Act as a technical lead, guiding junior engineers and setting the standard for hardware design best practices across the company
