Position Summary:

The Senior Demand Planner will own the SKU-level demand plan for Momentous' retail business, managing forecasts for every individual retail account while serving as the data integrity backbone for the Planning team's reporting and master data.

This is a high-ownership, execution-focused role for an experienced demand planner who wants to run a defined book of business with precision. This role will drive both the numbers and the data quality behind every retail account, with direct visibility into monthly S&OP and a clear mandate to make the demand plan and the data underneath it trustworthy.

This role reports to the Director of Planning.

Responsibilities:

Demand Planning

• Build and maintain the SKU-level statistical forecast for all individual retail accounts.
• Lead account-level forecast collaboration, including sell-in/sell-through review, POS data reconciliation, promotional and event overlays, and account-specific seasonality.
• Run the monthly forecast review cadence with account and sales counterparts ahead of consensus demand review.
• Own forecast accuracy (MAPE/bias) at the account and SKU level; diagnose and correct root causes of variance.
• Present retail forecast risks and opportunities in the monthly S&OP demand review in partnership with sales.

Master Data & Data Integrity

• Own master data governance for the Planning function, including item attributes, account/location hierarchies, unit-of-measure conversions, and item lifecycle.
• Audit and maintain the data processes that keep planning reporting accurate, including forecast accuracy, bias, exception reports, and S&OP inputs.
• Catch and correct data issues before they reach leadership reporting.
• Partner with IT/Systems on data mapping and validation as Momentous migrates to Fulfil.io, including retail account- and SKU-level data.

Cross-Functional Execution

• Own the Excel-based demand plan model at the retail/SKU layer. This is the primary planning tool today, and strong model-building is essential.
• Support the Fulfil.io ERP transition from the demand planning side, including UAT, data validation, and process documentation for retail forecasting workflows.
• Provide backup coverage on other forecast groups during PTO/peak periods as a secondary responsibility.

Qualifications:

Education & Experience

• 5+ years of demand planning or S&OP experience, including direct retail account-level forecasting; bachelor's degree required.
• Hands-on ERP experience, ideally including an ERP implementation or migration.
• Demonstrated ownership of data accuracy or master data processes in a prior role.

Skills & Competencies

• Advanced Excel modeling; personally builds and audits forecasting models, not just operates templates built by others.
• Fluent in MAPE, bias, and forecast accuracy methodology; comfortable presenting forecast risk directly in an S&OP or executive forum.
• Strong working knowledge of retail account dynamics, including buyer relationships, POS data, sell-in/sell-through, seasonality, rep group relationships, and promotional planning.
• Experience with Fulfil.io is a plus.

Attributes

• Prefers depth over breadth and is motivated to build real expertise in a defined book of business.
• High accountability and strong follow-through; catches issues before they become problems.
• Comfortable owning both the analytical and operational sides of the role, including forecasting and data governance.
• Growth mindset and a desire for continuous improvement in work and process.
• Agility with time management and shifting priorities.

Benefits:
