At PolyPeptide, we partner with pharmaceutical and biotech companies to support the development and manufacturing of peptide-based therapies.

This role is ideal for a supply chain leader who enjoys solving complex material challenges, developing teams, managing suppliers, and ensuring critical materials are available to support production and customer commitments.

About the Role

The Purchasing / Materials Manager leads a team responsible for raw materials, solvents, reagents, resins, packaging components, and other critical supplies.

• Lead purchasing activities from requisition and purchase order placement through delivery and issue resolution.

• Manage material planning for production, development projects, and customer requirements.

• Review forecasts, inventory, safety stock, open orders, shelf life, and manufacturing schedules.

• Lead MRP reviews and address shortages, late deliveries, and supply risks.

• Develop recovery plans using expedited deliveries, approved substitutions, alternate suppliers, or revised priorities.

• Monitor supplier delivery, quality, responsiveness, lead times, and OTIF performance.

• Lead supplier performance reviews and corrective-action follow-up.

• Identify opportunities to improve pricing, payment terms, freight costs, and total cost of ownership.

• Manage inventory levels while balancing availability, working capital, shelf life, storage, and obsolescence risk.

• Maintain accurate purchasing and planning data in ERP systems.

• Support supplier qualification, audits, documentation, and change notifications.

• Lead, coach, and develop a team of approximately 3–5 direct reports.

• Establish clear priorities, standard work, and accountability across the purchasing and materials team.

• Partner with Finance on purchase-price variance, inventory, freight, and cost-saving initiatives.

What We Are Looking For

Education and Experience

• Bachelor’s degree in Supply Chain, Business, Operations, Engineering, Science, or a related field.

• 5+ years of progressive experience in purchasing, procurement, material planning, or supply chain.

• 5+ years of leadership or supervisory experience.

• Experience in pharmaceutical, biotechnology, chemical, or another regulated manufacturing environment strongly preferred.

• Working knowledge of GMP requirements and controlled documentation preferred.

Skills and Competencies

• Strong knowledge of purchasing, supplier management, MRP, inventory control, logistics, and ERP systems.

• Ability to analyze demand, supply, inventory, cost, and supplier data and turn it into clear actions.

• Strong negotiation, problem-solving, and risk-management skills.

• Effective people leadership, coaching, delegation, and cross-functional collaboration.

• Strong organization, communication, and prioritization skills.

• High level of accountability, attention to detail, and continuous-improvement focus.

What Success Looks Like

Success in this role includes improving:

• Material availability and raw-material coverage

• Supplier OTIF, quality, responsiveness, and lead times

• Production-impacting shortages

• Inventory levels, expiry risk, and working capital

• Purchase price, freight, and total cost

• ERP and master-data accuracy

• Team capability and performance

Why Join PolyPeptide?

This role has a direct impact on whether materials are available, production stays on schedule, and customer commitments are met.

You will have the opportunity to lead a team, support two Southern California sites, strengthen supplier partnerships, and improve supply chain performance in a regulated pharmaceutical manufacturing environment.
