Lead manufacturing execution activities for data center cooling product lines, ensuring products move efficiently from development into stable, scalable production.
-
Serve as the primary engineering liaison between internal engineering, operations teams, and external manufacturing partners and contract manufacturers.
-
Own and maintain manufacturing quality systems, including control plans, PFMEAs, PPAP documentation, and other quality-related processes.
-
Drive process improvements and continuous improvement initiatives across manufacturing operations to enhance throughput, yield, and reliability.
-
Manage production readiness activities for new products (NPI), including production ramp planning, validation, and documentation control.
-
Ensure robust documentation control for manufacturing processes, including work instructions, assembly procedures, and build documentation.
-
Monitor and improve supplier performance, including supplier quality, delivery, and responsiveness, through strong vendor and supplier management.
-
Conduct and lead root cause analysis and root cause failure analysis for manufacturing and quality issues, and implement effective corrective and preventive actions.
-
Support electromechanical assembly processes, including sensor manufacturing, PCB assembly, enclosures, housings, injection molding, and related operations.
-
Develop, review, and optimize control plans, PFMEAs, and work instructions to ensure consistent, high-quality manufacturing outcomes.

Collaborate closely with contract manufacturers to troubleshoot production issues, optimize processes, and support production ramp activities.
-
Interpret electrical schematics, bills of materials (BOMs), assembly drawings, and manufacturing documentation to support build accuracy and product quality.
-
Lead or support automation initiatives and lean manufacturing projects to improve efficiency, reduce waste, and standardize processes.
-
Engage directly on the shop floor to work hands-on with products, fixtures, tools, and manufacturing processes to resolve issues in real time.
-
Support and influence the design and implementation of manufacturing systems that can scale with multi-year growth in data center cooling products.
-
Communicate effectively with engineering leadership, operations, suppliers, and contract manufacturers, providing clear updates on issues, risks, and progress.
-
Work independently with limited supervision, taking high ownership of outcomes and driving tasks to completion in a fast-paced environment.

Work Environment
This role operates in a hybrid office and manufacturing environment focused on level measurement and control instrumentation used across chemical processing, water and wastewater, energy, industrial automation, and fluid management applications. Products are manufactured under defined quality standards and sold globally, with substantial growth driven by increasing demand for AI and data center infrastructure, particularly within data center cooling product lines. The position involves frequent interaction with contract manufacturers and an approximate 50/50 split supporting manufacturing partners in two primary locations. You will spend significant time on the shop floor in a hands-on capacity, working directly with products, fixtures, manufacturing processes, and production issues. The environment is small-company and lean, requiring high ownership, self-direction, and the ability to make decisions quickly. You can expect high visibility with engineering leadership and operations, direct influence over manufacturing scale-up activities, and the opportunity to help build manufacturing systems that support multi-year growth.
