Supply Planning Manager

About The Role

Clean Nutra sells across Amazon FBA, TikTok Shop, Shopify, Walmart, and our own in-house warehouse — and inventory accuracy across every channel is non-negotiable. We're looking for a Supply Planning Manager to own inventory health company-wide: from our physical warehouse to every seller platform we operate on. This is not a warehouse-only role. You'll be responsible for supply planning, replenishment, PO generation, and channel allocation — making sure the right product is in the right place at the right time, at every level of the operation.

What You'll Do

• Own inventory accuracy and health across all sales channels — Amazon FBA (domestic and international), TikTok Shop (FBT), Walmart (WFS), Shopify, iHerb and other vendor/partner accounts, and in-house warehouse
• Lead supply planning: demand-driven replenishment, PO generation, and channel inventory allocation to prevent stockouts and overstock situations
• Manage Amazon FBA domestic inventory — inbound shipments, restock alerts, stranded inventory, storage limits, and fee optimization; prepare for and support Amazon international FBA expansion in the upcoming quarter
• Manage TikTok Shop FBT (Fulfilled by TikTok) inventory — inbound prep, stock positioning, and platform compliance
• Manage Walmart WFS inventory — inbound routing, OTIF compliance, and stock level maintenance
• Manage vendor and partner inventory for accounts such as iHerb — stock replenishment, order fulfillment coordination, and inventory visibility
• Oversee physical inventory operations: cycle counts, spot checks, reconciliations, and variance resolution
• Ensure accurate inventory data across all systems — WMS (ShipHero), ERP (Cin7), and platform seller portals — and resolve sync issues quickly
• Cook up inbound inventory flow: receipts from manufacturers, 3PL transfers, and FBA prep and shipment creation
• Build and enforce SOPs for inventory management, replenishment workflows, and cross-channel allocation
• Track and report on inventory KPIs: accuracy rates, channel-level stock positions, days of supply, shrink, and fulfillment error rates
• Identify and escalate supply risks before they become stockouts — proactive, not reactive
• Partner with supply chain, finance, and operations leadership on inventory planning and capital efficiency

What We're Looking For

• 7–10+ years of inventory management or supply planning experience in a multi-channel eCommerce or CPG environment
• Hands-on Amazon FBA experience — you understand replenishment workflows, inbound shipment creation, storage limits, and how FBA inventory impacts rankings and buybox
• Experience with supply planning: demand forecasting, PO generation, and channel allocation across multiple platforms
• Proficiency with WMS and ERP systems — ShipHero and Cin7 experience strongly preferred
• Strong systems fluency — you can work across multiple platforms, identify data discrepancies, and resolve them without hand-holding
• Detail-oriented and data-driven — inventory accuracy is your standard, not your goal
• Able to work cross-functionally with supply chain, operations, finance, and sales teams

Bonus Points

• Experience managing inventory across TikTok Shop, Walmart Marketplace, or Shopify in addition to Amazon
• Background in supplements, health, or CPG — familiarity with lot tracking, batch management, or expiration dating
• Experience scaling inventory operations during rapid business growth
• Knowledge of Amazon FBA fee structures and storage optimization strategies

Why Clean Nutra?

• Full ownership of inventory across a $150M+ operation spanning multiple high-volume sales channels
• A company scaling fast — what you build here will matter, and you'll see the impact directly
• Competitive base ($100K) plus a performance bonus tied to results, and full benefits
• Direct access to operations and supply chain leadership — your recommendations get heard and acted on
