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.

• 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.

• 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.

Job description

About Mammoth Brands

Mammoth Brands (formerly Harry’s Inc.) is the modern CPG company behind brands Harry’s, Flamingo, Lume, Mando, and Coterie. We’re building a new model—and home—brands, founders, and talent looking to solve unmet needs, improve peoples’ lives, and ultimately challenge the status quo. Our mission is to “Create Things People Like More.” Simply put: everything we do should be better than what already exists. If it’s not, we don’t do it. This guides everything we do, from developing the best product experiences, to making Mammoth Brands a great place to work, to exploring innovative ways to give back to our community.

We got our start in 2013 when our co-founders created Harry's. They built the brand differently—online first, prioritizing direct relationships with customers—and in the process learned they’d created something bigger: a playbook and platform that could help other brands grow and scale to their full potential, and a vision to reimagine consumer packaged goods. Today, Mammoth Brands is a growing portfolio of brands and the largest CPG company built in the last 20 years. Even as we grow, we take extra care to maintain the small, scrappy, entrepreneurial culture that helped to get us where we are today: to create a company that people like more, that better serves its customers, employees, and community. As a company, we’re also committed to making a positive impact and have donated over $20 million through our network of nonprofit partners to date.

We build brands that move fast and think big — and we hire people who are curious about AI, willing to experiment with it in their day-to-day work, and excited to accelerate what's possible. We prioritize giving our team the tools, training, and space to build real fluency, so you grow alongside the technology and help shape how we use it.

About the Role

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, and 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.
