Mitsubishi Heavy Industries America, Inc. (MHIA) is looking for a
Principal Mechanical Engineer, Chillers to join our team. This is a hybrid role based out of our
Plano, Texas location.
SCOPE:The
Principal Mechanical Engineer, Chillers serves as the primary technical and commercial interface between customers and U.S.-based Modular Chiller Plants (MCP) and Dry Cooler manufacturers. The role ensures clear, aligned specifications and smooth execution from pre-award through commissioning. It manages system-level and interface coordination to support flexible chiller configurations across multiple suppliers. The position works cross-functionally to maintain a reliable, cost-effective supply base and ensure alignment on scope, schedule, cost, and compliance. It also develops new manufacturers by assessing capabilities, defining roles and interfaces, and building scalable, long-term partnerships.
The ideal candidate will have at least twelve (12) years of experience in supplier-facing technical coordination and oversight for industrial equipment, such as HVAC systems, centrifugal chillers, pumps, heat exchangers, packaged/skid systems, or /control systems.MHIA regrets that it cannot sponsor employment Visas or consider individuals on time-limited Visa status for this position.JOB RESPONSIBILITIES:Customer & Specification Alignment- Translate customer requirements into clear, complete, and supplier-facing specifications for Modular Chiller Plants (MCP) and Dry Cooler systems.
- Define MCP scope, including interface points, responsibility split, and boundary conditions among customers, MCP manufacturers, Dry Cooler manufacturers, and internal stakeholders.
- Handle technical inquiries from customers and suppliers, ensuring timely clarification and alignment at a system and interface level.
MCP Manufacturer Oversight (Order Intake & Execution)- Act as the primary commercial and technical interface with MCP manufacturers throughout pre-award and post-award phases.
- Align scope, roles, and responsibilities for MCP delivery, clearly defining who is responsible for what and where interface boundaries are set.
- Drive contract, schedule, and milestone alignment to enable timely procurement of long-lead items and protect the overall project critical path.
- Manage action items, escalation paths, and decision logs with MCP manufacturers and internal teams to close open points efficiently and maintain execution momentum.
- Identify, engage, and screen alternative MCP 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.
Dry Cooler Manufacturer Oversight- Collaborate with Dry Cooler manufacturers to develop project opportunities and align requirements and specifications at a front-end, system-integration level.
- Serve as the single intake point for MCP and Dry Cooler specifications and interface definitions, ensuring consistency before downstream execution.
- Drive cross-functional coordination across sales, engineering, supply chain, quality, and service teams, and manage risk and issue logs to mitigate technical and schedule risks.
Supplier Development & Supply Base Strengthening- Support the identification, qualification, and development of MCP and Dry Cooler manufacturers to build a robust, competitive, and scalable supply base.
- Promote vendor-agnostic system coordination, enabling projects to proceed with MCP, and Dry Cooler configurations without reliance on a single supplier or technical organization.
- Contribute to continuous improvement of specification processes, interface definition, and supplier collaboration models to support long-term business growth.

- Ability to read, review, and interpret technical specifications and drawings, including P&IDs, general arrangements (GA), electrical schematics, and I/O diagrams, at a system and interface level.
- Proven experience managing execution through issue tracking, change control, and cross-functional coordination across engineering, procurement, quality, and supply chain teams.
- Strong negotiation and coordination skills to support pre-award alignment on scope, schedule, responsibilities, and commercial assumptions.
- Solid project management capabilities, including action, risk, and issue tracking, escalation management, and alignment across multiple internal and external stakeholders.
- Domain knowledge of data center cooling systems, with an understanding of centrifugal chiller applications and MCP/Dry Cooler configurations at a system and interface level.
- Ability to front-end and triage customer and supplier specifications, clearly define scope and interface boundaries, and transition aligned inputs to internal engineering teams for downstream execution.
- Ability to effectively collaborate and communicate with Japanese stakeholders and team members in a global, cross-cultural working environment.
