Supply Planning Manager; Coterie

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.

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 Supply Planning Manager to own Coterie's end-to-end supply plan and help build the planning capabilities required for our next stage of growth.

As Coterie expands across DTC, Amazon, retail, wholesale, and emerging channels, our supply chain is becoming increasingly complex. We need someone who can translate demand into executable supply plans, anticipate constraints, optimize inventory investment, and ensure we have the right products in the right places at the right time.

This is a highly cross-functional role working closely with external manufacturers, logistics and warehouse partners, Demand Planning, Product Development, Operations, and Finance. You'll own the decisions and day-to-day execution that connect supplier production to inventory availability, while helping develop more sophisticated planning processes, systems, and capabilities.

The right person is equal parts planner, operator, analyst, and builder. You're comfortable getting into the details of a supplier order or inventory projection, but you also understand the broader financial and operational implications. You don't just identify problems. You anticipate them, evaluate tradeoffs, recommend solutions, and drive execution.

Your work will directly influence product availability, customer experience, working capital, and our ability to scale efficiently.

• Translate SKU-level demand forecasts into rolling supply, production, purchasing, and inventory plans across Coterie's product portfolio.
