They will serve as the primary technical interface between customers and U.S.-based power system manufacturers. The role ensures clear, aligned specifications and smooth execution from pre-award through commissioning. The position works cross-functionally to maintain a reliable, cost-effective supply base and ensure alignment on scope, schedule, cost, and compliance. They will also develop new manufacturers by assessing capabilities, defining roles and interfaces, and building scalable, long-term partnerships. This position collaborates with global stakeholders across Japan and the U.S. to align priorities, enable effective execution, and support MHIA's long-term business objectives.

Job Responsibilities

• Design and Development
• Develop new technologies and architectures in support of 800VDC and MV/LV power systems
• Provide support for new IP review and submission
• Review the market for new technologies and assess their viability and applicability
• Define scope for new power systems, including interface points, responsibility split, and boundary conditions among customers, manufacturers, and internal stakeholders
• Own design calculations and analysis packages (load flow, short circuit, protection coordination, arc flash, harmonics, transients/dynamic performance) and maintain traceability to requirements
• Customer & Specification Alignment
• Translate customer requirements into clear, complete, and supplier-facing specifications for new power systems
• Handle technical inquiries from customers and suppliers, ensuring timely clarification and alignment at a system and interface level
