THE ROLE As a Senior Supply Planner at Thrive Market, you own the supply chain integrity for a complex category or vendor portfolio — and you're accountable for outcomes, not just execution. You bring the analytical depth to diagnose systemic inventory problems, the vendor credibility to drive supplier accountability, and the cross-functional fluency to influence decisions upstream before they become downstream disruptions. You operate with minimal oversight, lead process improvement that scales beyond your category, and serve as a subject matter resource for planners at earlier career stages.
RESPONSIBILITIES Own end-to-end replenishment strategy and purchase order execution across a high-volume vendor set, including promotions, seasonal builds, and new product launches — with accountability for inventory turns, in-stock rates, and shrink outcomes. Lead and monitor in-stock performance: surface OOS risk early, own escalation decisions, and drive resolution through both internal and external channels before member experience is affected. Own vendor relationships: negotiating corrective action plans, and managing scorecards with a clear point of view on where supplier performance is acceptable versus where it requires structural remediation. Serve as a strategic cross-functional partner to Category Management, Merchandising, Marketing, Finance, and FC Operations — bringing supply-side perspective into promotional planning, launch sequencing, and inventory investment decisions. Lead process improvement initiatives with measurable operational impact: identify systemic inefficiencies, design solutions, and see them through implementation — including active contribution to Thrive Market's planning automation and system modernization roadmap. Mentor Supply Planners, providing guidance on analytical methods, vendor management, and decision-making frameworks; contribute to team skill development and operational consistency. Own stakeholder reporting for your category — translating inventory and in-stock data into clear narratives with explicit recommendations, not just summaries.
