Graham Architectural Products specializes in solving the industry's toughest challenges through beautiful, functional & energy-efficient window and door systems including casement, hung, sliding & projected windows, entrance doors, security & vandal screens, and window wall systems for demanding commercial & institutional projects.
We're looking for a Senior Plant Manager to own day-to-day operations across two York-area facilities: a large, highly profitable manufacturing plant and a smaller warehousing facility that also runs CNC & packaging operations. This is a highly custom, engineer-to-order manufacturing environment, different from standard build-to-inventory work, where production runs in close coordination with estimating, project management & customer-facing teams to meet demanding, lead-time-driven commitments.
This role is ideal for a collaborative, results-oriented operator who has already run a plant of significant scale & complexity, leads with lived lean/continuous-improvement discipline rather than certifications alone, and understands that in a custom manufacturing business, every operational decision has a direct & visible impact on the customer.
