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 want employees who are curious about AI and excited to accelerate what's possible.

About the team

As the Customer Supply Chain Manager, you’ll be embedded within the Retail team but sit within the broader Supply Chain organization, directly owning and driving operations across our retail and/or digital channel. You’ll lead Collaborative Planning, Forecasting, and Replenishment (CPFR), manage in‑stocks, on‑time/in‑full (OTIF) performance, and oversee store‑level operations and chargeback mitigation. From shelf to supply node, you’ll play a key role in ensuring product availability and exceptional execution for the Harry’s and Flamingo brands.

About the role

We’re seeking a highly motivated and collaborative individual to join our Customer Supply Chain (CSC) team. This critical role serves as the end‑to‑end supply chain lead for one of our key Retail or Digital channels. You’ll work cross‑functionally with our Commercial, Demand Planning, Operations, and Finance teams to ensure seamless product flow to customers. This role is both operational and customer‑facing; it requires fostering strong relationships with retail partners and a commitment to flawless operational execution.

We’re looking for an outstanding operational leader — someone who understands the nuances of retail and digital supply chains, moves quickly to solve problems, and uses data to drive prioritization and decisions. The ideal candidate is detail‑oriented, analytical, and a strong communicator, capable of setting strategy and executing against it. This is a high‑impact role that requires a balance of big‑picture thinking and roll‑up‑your‑sleeves execution.

What you will accomplish

• Partner with the sales team, demand planning, supply planning, and external counterparts to lead ongoing forecasting and replenishment needs for the business.
• Serve as the go‑to expert on retail operations for your channel, including fulfillment, warehousing, transportation, in‑store operations, display execution, retailer contract, allowance, and chargebacks.
• Lead retail operations activities within the relevant channel/retailer based on standard processes and data‑driven insights; measure return on investment for all retail ops activities to optimize investments.
• Manage third‑party brokers to ensure the highest level of execution around channel needs and requirements for each customer.
• Develop reporting & scorecarding linked to operational success metrics and key performance indicators.
• Identify gaps in current operational practices and work with retail operations, channel sales directors, and external partners to create strategic roadmaps for progress.
• Lead integrated business planning (IBP) in partnership with Demand Planning to provide accurate inputs on sales and changes in the business.
• Support strategic planning and execution: understand our company‑wide goals and KPIs and translate this into operational strategies and actions that support.
• Own end‑to‑end distribution logistics for your channel, ensuring on‑time fulfillment and delivery, managing sales order and inventory accuracy, and driving continuous improvement through chargeback analysis, KPI tracking (OTIF, in‑stocks), and retailer supply chain insights.

Supporting our Key Retail or Digital Channels include

• Conduct weekly replenishment analysis to ensure proper inventory flow between internal and external supply chains.
• Regular communication with regional buying teams to maintain healthy inventory levels during promoted and non‑promoted periods.
• Manage all aspects of retailer forecasts (Supply Plan), including in‑stocks, event management, execution of new and discontinued items, reducing waste, reporting, and analytics.
• Identify opportunities for store operational process improvements and help drive implementation with store operations partners.
• Build and maintain external and internal stakeholder relationships that will drive supply and demand efficiencies.
• Continuous improvement: drive improvements in how we execute based on specific challenges or opportunities in your channel.
• Project management: engage in and help create cross‑functional projects and drive them forward with relevant context and expertise from your channel.

This should describe you

• 3‑5 years of experience in retail operations, supply chain management, retail sales, or customer supply chain roles.
• Detail‑oriented and highly collaborative, with strong internal and external relationship management skills.
• Strong understanding of key supply chain tools and resources.
• Knowledge of supply chain processes such as forecasting & replenishment, financial planning, store operations, inventory management, order (retailer) management, and distribution & logistics.
• Strong project management skills, including organization and communication, with the ability to self‑start initiatives and lead multiple team members (including third‑party partners).
• Strong understanding of Excel and AI tools, with ability to cut through data to generate, prioritize, and communicate key operational insight.

Here's who you'll work with

• Reporting to the Manager of Customer Supply Chain.
• Working with Customer Supply Chain team leads and the broader Supply Chain organization.
• Collaborating closely with Commercial, Demand Planning, Operations, and Finance teams.

Benefits & perks

• Medical, dental, and vision coverage.
• 401(k) match.
• Equity in Mammoth Brands.
• Flexible time off and working hours.
• L&D stipend.
• 4 weeks sabbatical after 5 years; 6 weeks after 10 years; 8 weeks after 15 years.
• 20 fully paid weeks off for parents who give birth, or 16 fully paid weeks off for all other paths to parenthood.
• Fun in‑person and virtual events.
• Free products from our family of brands.

Base salary range: $91,600 – $114,500. Final compensation will be based on location, skill level, and experience.
