JOB SUMMARY

Mitsubishi Heavy Industries America, Inc. (MHIA) is looking for a Principal Electrical Engineer to join our team. This is a hybrid role based out of our Plano, Texas location.

ABOUT MITSUBISHI HEAVY INDUSTRIES AMERICA, INC. (MHIA)

For over 130 years, Mitsubishi Heavy Industries (MHI) Group’s innovative and integrated solutions have demonstrated our commitment to creating a positive social impact around the globe. Our range of products and services is tailored to meet our customers’ evolving needs across the commercial aviation, energy, transportation and infrastructure, machinery, defense, and space systems sectors.

Our culture embraces diversity and cooperation, and we promote a healthy balance of professional and personal development, ensuring that your ideas and expertise are valued and respected.

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.

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.

MINIMUM REQUIRED QUALIFICATIONS

• Education: Bachelor’s in electrical engineering or equivalent experience
• Experience: Minimum of twelve (12) years of experience with at least seven (7) years of experience in power system design for MV and LV applications
• Comprehensive understanding of power system design. Ability to lead architecture development for new applications
• Strong analytical skills in product development for power equipment in MV and LV applications. This includes power rectifier, inverter, converter, and UPS applications.
• Experience with simulation tools such as PSPICE, Matlab, SIMPLIS, and Ansys for design modeling and verification
• Knowledge of electrical codes and standards, including NEC, NFPA, IBC, and IEC.
• Understanding of EMI/EMC mitigation methods
• Understanding of data center power architectures (UPS/BESS integration, redundancy, maintainability, commissioning/FAT/SAT).
• Ability to perform system studies, including arc flash and coordination analysis
• Ability to create electrical schematics, bills of material, calculation packages, and technical reports
• Ability to think creatively and identify new opportunities
• Ability to build strong relationships with clients
• Excellent leadership and communications skills
• Collaborate with other engineers and stakeholders across multiple disciplines
• Interface with vendors to support detailed product development

PREFERRED QUALIFICATIONS

• Education: Master’s in electrical engineering or equivalent experience.
• Experience: Minimum of ten (10) years of experience in power system design for MV and LV applications
• Proven track record in developing new and innovative products, and seeing them to successful market entry
• Proven track record in project management, customer interface and support, and project testing and commissioning

WORKING CONDITIONS

• Travel: 25%
• Standard Monday through Friday work week. Weekend/late-night work if applicable.
