Job summary

You’ll build forecasts, monitor accuracy, and lead launches and transitions, shaping how demand planning evolves as the business scales.

Responsibilities

• Own Coterie's end-to-end demand forecast across DTC, Amazon, retail, wholesale, and other marketplace channels, from total business demand down to customer and SKU level.
• Build and maintain rolling forecasts incorporating historical performance, run rates, seasonality, promotions, marketing plans, retail sell-through, customer forecasts, product launches, and other demand drivers.
• Develop customer-level forecasts for our growing wholesale and retail business.
• Translate new commercial initiatives into demand and inventory requirements before they hit the business.
• Develop a clear, independent point of view on demand rather than simply aggregating inputs from other teams.
• Partner with Sales, Marketing, Finance, and Leadership to align the organization around a single, trusted demand plan.
• Own forecast accuracy and bias measurement and continuously improve both.
• Diagnose forecast misses to distinguish signal from noise and identify where assumptions, inputs, methodology, or process need to change.
• Build meaningful reporting and KPIs that help the organization understand what changed, why it changed, and what we should do about it.
• Identify emerging demand trends, upside opportunities, and inventory risks early enough for the business to act.
• Create the operating rhythms and accountability that make the forecast a trusted source of truth across the company.
• Partner closely with Supply Planning to translate demand into inventory requirements and surface future constraints, risks, and opportunities.
• Monitor wholesale and retail performance against forecast and quickly incorporate new information into the demand plan.
• Translate commercial plans into clear inventory implications and actionable recommendations.
• Support healthy inventory by balancing service levels and growth opportunities against excess inventory and working capital.
• Communicate forecast changes and their downstream implications clearly so Operations, Finance, and commercial teams can make better decisions faster.
• Serve as a key contributor to Coterie's evolving S&OP process, including monthly demand reviews and executive decision support.
• Build initial forecasts for new products, SKUs, retail customers, and channel launches.
• Translate launches into SKU-level demand and inventory requirements.
• Develop depletion and cutover plans for packaging changes, assortment updates, and product transitions, minimizing excess inventory while protecting customer service.
• Plan inventory requirements for kits, bundles, samples, partnerships, promotions, and channel-specific programs.
• Support retail expansion and new customer launches by translating business plans into SKU-level demand.
• Navigate incomplete data and ambiguous inputs without waiting for someone else to hand you the answer.
