Key duties include supplier management, monitoring inventory levels via MRP tools and planning analysis, and managing supplier relationships to ensure quality and on-time delivery. The role also involves collaborating with production and warehouse teams to resolve delivery and quality issues as well as Service support requirements.

• On-Site Collaboration: Work directly alongside our Methuen plant floor, quality team, and engineering staff to rapidly resolve material shortages, dimensional discrepancies, or quality issues.
• Direct Materials Management: Optimize NetSuite MRP parameters and demand planning to ensure optimal direct material flow. Comfortable with ad hoc demand planning analysis and demand interpretation.
• Supplier Management: Identify, audit, and onboard supply partners. Manage supplier performance and productivity improvement initiatives.
• Drawing Interpretation: Review engineering drawings and BOMs to assess supplier manufacturing capability, tolerances, and ensure accurate quoting.
• Cost Optimization: Lead supplier negotiations, establish long-term pricing agreements, and execute cost-reduction initiatives to improve gross margins.
• Engineering Alignment: Partner closely with Manufacturing Engineering to manage Engineering Change Orders (ECOs) and prototype sourcing for new product introductions (NPI).

Requirements

• Education: A Bachelor’s degree in Supply Chain, Business Administration, or a related field.
• Experience: 5+ years of experience in a mechanical Purchasing role, ideally in a small to mid-size manufacturing environment.
• ERP Proficiency: Mandatory, hands-on experience utilizing NetSuite or a comparable ERP system for inventory management, procurement workflows, and material tracking.
• Schedule: Ability to work 100% on-site at our Methuen, MA production facility and manage concurrent priorities in a fast-paced, hands-on environment.
• Data Savvy: Advanced Microsoft Excel skills (VLOOKUPs, Pivot Tables) to synthesize data extracted from NetSuite.
• Specific Commodity Expertise: Prior experience purchasing custom sheet-metal fabrications (stamping, welding, laser cutting) and plastic molded components (injection molding, rotomolding, thermoforming) preferred.
• Low-cost Region Sourcing Experience (Particularly Asia and Mexico) preferred.
• Certifications: APICS (CPIM/CSCP) or ISM (CPM/CPSM) designation preferred.
