1d • $91,600 - $115,000 • Hybrid

About The Position

The Supply Planner, Manager, will develop time-phased supply plans and inventory strategy for multiple product categories at Mammoth Brands. You will serve as the primary point of contact for these categories — both to internal cross-functional partners and to external contract manufacturers — and will set strategy, manage work end-to-end, and drive measurable outcomes. This is a cross-functional role for someone who plans and prioritizes independently, can take something from idea to execution without hand-holding, and operates as a true go-to for their area of expertise.

Requirements

• BA or equivalent required; advanced degree or supply chain certification a plus.
• 4–6 years of experience in supply and/or inventory planning, ideally in a CPG environment.
• 4+ years of broader operations experience.
• Strong analytical and quantitative skills; proven ability to develop inventory models for complex supply networks.
• Strong communicator — you tailor your message to your audience, whether you're presenting to leadership, aligning with peers, or working through details with manufacturing partners.
• You plan and prioritize your own work independently, adjust in real-time as business needs shift, and take projects from idea to execution without needing constant direction.
• You are enthusiastic and committed at every stage of a product life cycle — from launch to end of life.
• Experience with ERPs required; SAP strongly preferred.
• Sense of urgency and bias for action — self-starting, organized, and adept at working within deadlines.
• Comfortable in a fast-paced, omni-channel environment (DTC + Retail); you stay focused when priorities shift.
• You're a learner — always seeking to improve yourself, your team, and the world around you.
• Attention to detail: you're comfortable going deep into the weeds while always keeping the big picture in view.
• Sense of humor — we take our work seriously and ourselves un-seriously.

Responsibilities

• Own the development and continuous refinement of time-phased supply plans and inventory strategy across multiple product categories.
• Optimize service and inventory levels by SKU at each node of the supply chain (plant, co-packer, in transit, DC).
• Collaborate with a network of contract manufacturers on production scheduling and supply needs to ensure plans are executable.
• Work closely with cross-functional partners to obtain high-quality demand, supply, logistics, distribution, finance and other inputs to create a robust assumption-based inventory plan.
• Track and drive reduction in excess and obsolete inventory.
• Model scenarios and understand the impacts of changes to demand, supply, and network assumptions; communicate tradeoffs and recommendations to stakeholders.
• Develop a clear set of KPIs and targets to monitor and improve production, service, and inventory performance.
• Partner with cross-functional teams to identify process inefficiencies and implement recommendations for continuous improvement.
