About the Job

We are partnered with a leading global supplier of rigid packaging on the search for a Senior Demand Planner. This role supports the demand review process within the company's broader Sales & Operations Planning (S&OP) process, with responsibility for improving processes and mentoring others.

This person will act as the integration point between Sales, Supply Chain, and Production Planning, owning item-level forecasts and working directly with customers, Sales, and Account Management to translate demand signals into actionable plans.

The company serves virtually every major end market-automotive, beverage, food, home care, industrial chemical, pet care, personal health and beauty, and wine and spirits, among others-and this role will be central to how demand planning scales alongside that growth.

The Mandate

This organization is clear about what it is-and is not-seeking.

They are not looking for someone who simply inputs numbers into a forecasting system.

They are seeking a demand planning expert and mentor: someone who can own forecasts end-to-end, build trust directly with customers and Sales, root-cause forecast variance, and help develop the planning skills of others on the team.

Key Responsibilities

• Own and maintain monthly item-level forecasts, including new products, across assigned customers and markets
• Lead regional and local demand reviews with Sales and Account Management, driving alignment on assumptions, risks, opportunities, and the unconstrained demand plan
• Serve as a customer-facing demand planning expert, building customer confidence in forecasting and business management capabilities
• Partner directly with customers, Sales, and Account Management to translate demand drivers and changes in customer behavior into actionable forecasts
• Analyze historical trends, orders, inventory, market intelligence, and other demand signals to develop and continuously improve forecasts
• Monitor forecast accuracy and bias, identify significant variances, and lead root-cause analysis and corrective actions
• Partner cross-functionally with Sales, Supply Planning, Operations, and other stakeholders to align demand and supply plans
• Drive continuous improvement through demand segmentation, exception management, and improved planning processes
• Ensure planning tools (e.g., Kinaxis) are used effectively and consistently across the team
• Proactively communicate material demand changes, customer issues, and business risks to regional and central Supply Planning
• Develop and maintain reporting and insights that support business decisions and the S&OP process
• Mentor team members on demand planning and S&OP skills, including statistical forecasting and advanced planning tool functionality

Ideal Profile

• Bachelor's degree in Supply Chain Planning or equivalent
• 5+ years of experience in demand planning or a related role
• Working knowledge of demand planning systems such as Kinaxis, Logility, or Blue Yonder
• APICS CPIM certification preferred
• Strong understanding of supply chain functions including demand, replenishment, and sourcing
• Strong analytical and problem-solving skills with a systems/process orientation
• Excellent communication, presentation, and negotiation skills, with the ability to influence at all levels
• Experience developing or leading others
• Comfortable navigating complexity and competing priorities in a collaborative environment
• Highly organized and detail-oriented, with strong time management skills

Location & Work Model

• Ontario, CA - onsite at the company's Sales and Distribution Center office
• Not eligible for immigration sponsorship

Compensation

• Base salary: $95,000 - $115,000
• Role is also eligible for the company's full benefits package, including profit sharing, 401(k) match, and tuition/health club reimbursement
