Senior Demand Planner - Onsite - up to $115,000

In a world of noise, we find the signal — the pulse of potential. We weave the strands of talent, vision, and purpose into organizations that endure. Blending intelligence with intuition, we honor the human art of connection at the heart of every great company.

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
