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.

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. This list of responsibilities is not all‑inclusive, and an employee may be required to perform other relevant duties as assigned.
