About the Role

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.

Key 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.

Required Qualifications

• Education: BS/MS in Electrical Engineering or a related field.

• Experience: 10+ years of experience in high-complexity hardware design, specifically within the semiconductor, server, or networking industries.

• Board Design: Mastery of Cadence Allegro/Orcad or similar high-end EDA tools.

• Power & Signal Integrity: Deep understanding of SI/PI fundamentals, including jitter, crosstalk, and impedance control for 32Gbps+ signals.

• Laboratory Skills: Proficiency with high-speed oscilloscopes, BERTs, and VNA/TDR for hardware bring-up and validation.

• Communication: Ability to distill complex technical trade-offs into actionable decisions for executive leadership.

Preferred Skills

• Experience with OCP (Open Compute Project) standards or large-scale data center deployments.

• Knowledge of liquid cooling integration for high-TDP hardware.

• Nice to have: Familiarity with FPGA prototyping and emulation platforms.
