What You’ll Get to Do

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.

Key Responsibilities:

• Own full plant operations across both York facilities manufacturing, warehousing, CNC & packaging driving safety, quality, OpEx, production & efficiency
• Lead, mentor & develop managers and supervisors across multiple disciplines, building a winning culture & strong succession bench
• Partner closely with estimating, project management & customer service to ensure production schedules & product standards meet demanding lead times
• Champion daily, hands-on lean/continuous-improvement execution on the shop floor  spotting waste & opportunity in real time
• Lead plant optimization & automation transformation initiatives, championing new technology, robotics & control systems to modernize operations
• Drive continuous improvement projects that reduce downtime, improve throughput & increase Overall Equipment Effectiveness (OEE)
• Create, recommend & manage capital projects, including automation & equipment upgrades, from business case through implementation
• Partner with engineering & IT to integrate MES/ERP systems, data analytics & real-time reporting into daily plant decision-making
• Build strong working relationships with sales & customers, applying emotional intelligence & clear communication to manage expectations in a custom, deadline-driven environment
• Guide teams through technology-driven & organizational change as the plant modernizes & the business continues to grow
