Job description

ABOUT THE POSITION

The Sr. Demand Planning Analyst will play a key role in building and formalizing our demand planning capabilities from the ground up as we implement a new Sales, Inventory & Operations Planning (SIOP) process. This highly analytical, hands-on role will develop statistical forecasts, integrate customer and sales inputs, and help formalize how demand inputs are gathered, evaluated, and translated into a demand plan. Partnering cross-functionally, you'll improve forecast accuracy, increase transparency, and help define the processes, governance, and tools that will scale demand planning across the organization.

OUR IDEAL CANDIDATE

You're a curious, data-driven yet creative problem solver with 4+ years of experience in demand planning, forecasting, or supply chain analytics and a bachelor's degree in a related field. You understand forecasting models beyond theory and can apply them using tools like advanced Excel, SQL, Python, or R to turn complex data into actionable insights. You're comfortable working in ambiguity, pulling together inputs from multiple sources, and influencing cross-functional stakeholders with clear, practical recommendations. Experience with SIOP, S&OP, or IBP is strongly preferred, especially in evolving environments, and you bring a strong ownership mindset with a passion for building processes, improving forecast accuracy, and driving better business decisions.

HOW YOU WILL MAKE A DIFFERENCE

You will INNOVATE by:

• Developing, maintaining, and improving statistical demand forecasts at multiple levels (item, customer, product family).
• Evaluating and selecting forecasting methods (e.g., time series, trend, seasonality, exception-based forecasting).
• Analyzing historical demand, order patterns, and forecast drives to improve forecast accuracy and bias.
• Incorporating sales input and overrides in a structured, auditable manner to create a consensus demand plan.
• Partnering with IT and Supply Chain teams to support the implementation or enhancement of forecasting and planning tools.
• Identifying opportunities to improve data quality, automation, and forecasting efficiency.

You will EXPLORE by:

• Monitoring and reporting forecast performance using KPIs such as MAPE, bias, forecast accuracy, and forecast value add (FVA).
• Extracting, transforming, and analyzing data from ERP systems, customer forecasts, and external sources.
• Building and maintaining analytical models, reports, and dashboards to support demand planning and SIOP decisions.
• Comparing statistical forecasts to customer-provided forecasts and identify variances, risks, and opportunities.
• Supporting the monthly SIOP cadence by preparing demand reviews, variance analyses, and scenario insights.

You will PERFORM by:

• Clearly communicating forecast assumptions, changes, and risks to cross-functional stakeholders.
• Assisting in the design, documentation, and rollout of new demand planning and forecasting procedures.
• Helping define forecast ownership, data governance, planning horizons, and review cycles.
• Supporting the development of standard work, templates, and dashboards to enable scalable demand planning.

We offer competitive wages and the following great benefits

• Health, Dental, and Vision insurance
• Short term & Long-term disability insurance
• 401k with employer match
• Paid time off, including Vacation, Sick & Personal Time, and 11 paid Holidays
• Generous Profit-Sharing Plan
