Buyer - Supply Chain Planning (Lancaster County)

Help build the cleanrooms where life-saving medicines are made.

AES Cleanroom Technology is a leading design-build company specializing in cleanroom environments for the life sciences and pharmaceutical industries. Our work helps our clients manufacture the therapies patients depend on. We're growing, and we're looking for a Buyer who wants to make a visible impact on complex, high-stakes construction projects.

Based at our innovation facility and warehouse in Manheim, PA, you'll own the purchasing and material planning that keeps our projects on schedule — working directly with project managers, designers, and estimators, and with a real voice in how we buy. Relocation assistance is not provided, so candidates should live within commuting distance of Manheim.

WHY YOU'LL LIKE WORKING HERE

• Meaningful work: Your purchasing decisions directly support pharmaceutical and biotech manufacturing.
• Growth: Join a growing company with facilities in PA and GA and room to expand your role as we scale.
• Ownership: Manage your own product categories and supplier relationships — not just process POs.
• Collaboration: Work side-by-side with construction, design, and estimating teams who value your input.
• Benefits: medical, dental, vision, 401(k) with match, vacation, paid holidays

WHAT YOU'LL DO

• Plan material requirements and forecast demand based on project schedules and trends
• Create, issue, and manage purchase orders with approved suppliers, and track open POs through delivery
• Source products strategically and negotiate pricing, terms, and lead times to control costs and protect margin
• Maintain healthy inventory levels at our Manheim warehouse — minimizing stockouts and excess stock
• Coordinate delivery timelines with suppliers so materials arrive when our job sites need them
• Build strong vendor relationships and evaluate supplier performance on cost, quality, and on-time delivery
• Partner with project managers, designers, and estimators to resolve supply issues and manage change orders
• Build demand plans and track KPIs in Excel; keep data accurate in our planning/ERP system
• Develop in-depth knowledge of your product categories and their supplier base

WHAT YOU'LL BRING

• 3–5+ years of experience in purchasing, buying, procurement, demand planning, or material planning
• Bachelor's degree in supply chain, business, or a related field — or equivalent work experience
• Strong Excel skills (pivot tables, VLOOKUP/XLOOKUP, building forecasts)
• Experience with MRP, inventory control, and purchase order management
• Solid negotiation, communication, and problem-solving skills
• A detail-oriented, organized approach and the ability to juggle multiple projects and deadlines

NICE TO HAVE

• Experience in construction, manufacturing, or project-based purchasing
• Ability to read construction drawings, blueprints, or design documents
• APICS/ASCM (CPIM, CSCP) or ISM (CPSM) certification

Don't meet every qualification? We still encourage you to apply. If you have strong purchasing or planning experience and are eager to learn the construction side, we'd like to hear from you.
