Principal Electrical Engineer to join our team. This is a hybrid role based out of our
Plano, Texas location
SCOPE:The Principal Electrical Engineer is responsible for product-level engineering of 800VDC power distribution and MV/LV systems for data center applications, from architecture through validation. 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. 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.
The ideal candidate will have a minimum of twelve (12) years of experience, including at least seven (7) years in power system design for MV and LV applications.
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.
- Act as the primary technical interface with power system manufacturers throughout pre-award and post-award phases.
- Align scope, roles, and responsibilities for product delivery, clearly defining who is responsible for what and where interface boundaries are set.
- Drive contract, schedule, and milestone alignment to enable the timely procurement of long-lead items and protect the overall project critical path.
- Identify, engage, and screen alternative manufacturers to support opportunity development and future sourcing flexibility.
- Coordinate high-level specification, system configuration, and interface alignment during early project phases to support bid development and feasibility assessment.
- Support bid competitiveness by clarifying assumptions, exclusions, and system-level responsibilities, ensuring consistent and aligned proposal content.
Supplier Development & Supply Base Strengthening- Support the identification, qualification, and development of power system manufacturers to build a robust, competitive, and scalable supply base.
- Promote vendor-agnostic system coordination, enabling projects to proceed with power systems without reliance on a single supplier or technical organization.
- Contribute to the continuous improvement of specification processes, interface definition, and supplier collaboration models to support long-term business growth.
- Lead vendor design reviews and manage deviation/issue closure through corrective actions and design improvements.
- This list of responsibilities is not all-inclusive, and an employee may be required to perform other relevant duties as assigned
