Purchasing Jobs in Boulder, CO

Sr. Procurement Specialist

Our team at H3X is looking for a Sr. Procurement Specialist to execute day-to-day purchasing as we scale our manufacturing and introduce multiple new products. You will place and manage POs with approved suppliers, keep our supplier data current and reliable, and work on forecasting and supplier performance. This role is a great fit for someone who's detail-oriented, proactive by nature, and wants to grow into a broader supply chain or category management career as the function matures.

You are a strong fit if you've worked in procurement or buying for a complex, low/mid-volume manufacturer, you take ownership of accuracy and follow-through, and you like the idea of helping shape processes (forecasting models, category management, supplier KPIs) rather than just executing against them.

Purchasing Execution

• Place POs with approved suppliers for needed parts, maintaining a proactive rather than reactive posture on lead times and material availability
• Own the overall accuracy and reliability of PO data, quantities, pricing, dates, and terms
• Track deliveries against POs and follow up with suppliers to keep orders on schedule

Supplier Management

• Maintain and continuously update the supplier database, including onboarding new suppliers
• Ensure supplier certifications and NDAs are current and properly tracked
• Assist in maintaining supplier relationships & partnerships
• Actively participate in building out a Supplier KPI database to track and improve supplier performance

Planning & Forecasting

• Develop forecasting models together for distribution to key suppliers
• Support long-term planning efforts by keeping PO and supplier data organized and accessible
• Flag supply risks
• Coordinate with other team members across manufacturing engineering, production, and others

Cross-Functional Collaboration

• Work with Leadership to support cash flow planning based on PO data and timing
• Contribute to the development of category management as the supply chain function matures (e.g., Power Electronics, Electromagnetics, and other key commodity areas)
• Partner with engineering, production, and inventory teams as needed to keep purchasing aligned with real-time needs

Reporting

• Provide monthly reporting on purchasing activity, supplier performance, and open risks

What We Are Looking For

• 5+ years of experience in buying, procurement, or purchasing, ideally in complex mechanical, electromechanical, or electronics manufacturing
• Strong attention to detail and a track record of maintaining accurate, reliable purchasing data
• Experience managing supplier relationships and tracking supplier documentation (certifications, NDAs, etc.)
• Comfortable working with ERP/MRP systems for PO issuance and tracking
• Strong communication skills and ability to work cross-functionally with finance, engineering, and operations
• A proactive mindset, comfortable flagging risk early rather than waiting for it to become urgent

Preferred Experience

• Experience with Manufacturo or similar ERP/MRP platforms
• Exposure to forecasting or demand planning processes
• Familiarity with electronics or electromechanical component categories (e.g., power electronics, electromagnetics)

Compensation & Benefits

• Salary Compensation Range: $88,000 - $120,000
