Requirements
Director of Fabrication - This Is Where You Come In
MacDonald-Miller is looking for a Director of Fabrication to lead the performance, growth, and strategic development of fabrication operations across our enterprise. Overseeing our Seattle (Norfolk), Portland, and Kennewick facilities, you will ensure our shops have the people, processes, technology, equipment, and capacity to support the company’s expanding Off-Site Manufacturing (OSM) strategy.
As MacDonald-Miller grows its offsite capabilities—particularly multi-trade racks, pipe and duct spooling, equipment skids, risers, and modular assemblies for Mission Critical and data center clients nationwide—you will build the operational foundation to deliver increasingly complex work safely, efficiently, and consistently.
Serving as the connection point between fabrication, field operations, estimating, preconstruction, project management, and executive leadership, you will align what we sell with what our shops can reliably deliver. You will own enterprise fabrication planning, production performance, capacity and capital investment, quality systems, and shop financial metrics while partnering with Trade Superintendents, Trade General Foremen, and Union Halls to ensure our workforce can scale with demand.
This is a highly visible leadership role for a strategic, hands-on operator who can translate business growth into practical execution. You will shape the future of MacDonald-Miller’s fabrication network, build high-performing teams, and establish the systems and standards that make fabrication a measurable, predictable, and scalable competitive advantage.
