• D-Matrix is looking for a Principal Systems Hardware Engineer to own system architecture end-to-end — from concept through specification, design review, and production deployment
• In this role, you’ll act as the technical anchor for hardware decisions across interconnect, board, chassis, and rack-scale design, writing the specifications that partners and internal teams build against
• You’ll work independently against your objectives — setting technical direction without needing explicit guidance — while partnering closely with cross-functional teams and software groups to align hardware decisions with performance and workload needs
• You’ll review partner and vendor designs against requirements, surface misalignment and schedule risk early, and drive trade-off analysis across adjacent domains like interconnect, power, thermal, and mechanical
• You’ll also help establish the spec standards, review practices, and AI-assisted workflows that shape how d-Matrix builds systems at scale
• Own system architecture end-to-end — from concept through specification, design review, and production deployment — as the technical lead across teams and partners
• Author system, board, and rack specifications, and review partner designs against them — surfacing misalignment and schedule risk early
• Set direction for interconnect architecture — scale-up and scale-out fabrics, NICs, switches, optics, and topology — partnering with domain specialists to execute
• Set direction for board, chassis, and system architecture — component placement, PCB design, connectors, power, and thermal — at chassis, rack, and data-hall scale, partnering with domain specialists to execute
• Evaluate competing design options through trade-off analysis and “what-if” scenario planning
• Define validation, bring-up, and qualification strategy for new platforms
• Partner with software teams to align hardware decisions with performance and workload needs, and help establish spec standards and review practices for the org
