About the role

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 high-ownership, execution-focused role is ideal for an experienced demand planner who wants to run a defined book of business with precision. The 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: item attributes, account/location hierarchies, unit-of-measure conversions, and item lifecycle (new item setup, discontinuations).
  • Audit and maintain the data processes that keep planning reporting accurate—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 (not just template use) is essential.
  • Support the Fulfil.io ERP transition from the demand planning side: 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.

Requirements

• 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: 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—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—forecasting and data governance alike.
  • Growth mindset and a desire for continuous improvement in work and process.
  • Agility with time management and shifting priorities.

Benefits

• Competitive cash compensation plus employee stock options
• Health, vision, and dental insurance
• 401k match
• Unlimited PTO
• Finish Line Fridays—finish at 3:00 PM every Friday
• 18 days of observed holidays (office closure in 2026)
• $1,000 annual perks program to support a high-performance lifestyle
• Access to Momentous products and merchandise
