[Hiring] Demand Planning Manager @Mammoth Brands

Role Description

Coterie is a modern baby care brand for discerning parents. We design high-performance diapering solutions for some of the biggest parenting challenges. Our products are built to outperform conventional options, and now, as part of Mammoth Brands, Coterie is positioned to accelerate growth and continue raising the standard in baby care.

We're looking for a Demand Planning Manager to own Coterie's demand forecast and help build the planning capabilities required for our next stage of growth. This is a fully remote role with significant ownership and visibility across the business. You'll own our SKU-level demand plan across DTC, Amazon, retail, wholesale, and emerging channels while helping build the processes, tools, and operating rhythms required to support a rapidly scaling omnichannel business.

This isn't a role where you'll inherit a mature planning function, update a forecast once a month, and send out a report. You'll sit at the intersection of:

• Sales
• Marketing
• Finance
• Supply Chain
• Operations
• Leadership

Turning commercial plans, customer signals, historical performance, launches, promotions, and imperfect information into a clear point of view on what we're going to sell and what inventory we'll need to support it.

The right person is equal parts planner, analyst, operator, and builder. You can get deep into a SKU-level forecast, challenge an assumption from the commercial team, identify the business implication behind a forecast miss, and then build a better process so the same problem doesn't happen twice.

Your work will directly influence inventory, working capital, customer experience, and profitable growth, and you'll have the opportunity to shape how demand planning works at Coterie as we scale.

Qualifications

• 5+ years of experience in demand planning, inventory planning, merchandise planning, supply chain, or a similarly analytical planning role.
• Experience personally owning SKU-level demand forecasts in a consumer products, retail, CPG, or omnichannel business.
• Strong command of forecasting fundamentals, including seasonality, promotions, new product launches, trend analysis, forecast accuracy, and bias.
• Experience planning across multiple channels such as DTC, retail, wholesale, Amazon, or marketplaces.
• Exceptional Excel or Google Sheets skills.
• Strong analytical judgment and the ability to turn large amounts of imperfect data into clear business recommendations.
• Experience working with ERP, planning, BI, or automation tools. NetSuite, Parabola, Looker, or similar experience is a plus.
• Strong communication skills and the confidence to challenge assumptions constructively and influence people who don't report to you.
• A track record of improving the processes, models, or systems around you rather than simply operating what already exists.

Requirements

• 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.
• Help build planning capabilities by continuously improving our demand and inventory planning models, reporting, and workflows.
• Automate manual work and improve data quality, visibility, and speed.
• Help define the KPIs, reporting, SOPs, and planning cadences that should exist as the organization grows.
• Work with tools including NetSuite, Parabola, Google Workspace, and future planning technology.
• Help implement and optimize future demand and supply planning systems.
• Build processes that are rigorous enough to scale without becoming unnecessarily complicated.
