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.

REQUIREMENTS

• Bachelor's degree in Supply Chain, Economics, Finance, or a related analytical field.

• 5–8 years of experience in supply planning, replenishment, inventory management, or a closely related analytically driven role, with demonstrated progression in scope and complexity — preferably in retail, e-commerce, or distribution.

• Hands-on experience with BI tools (Domo, Snowflake, or equivalent); able to independently design and build reporting infrastructure, not just pull existing reports.

• Advanced Excel skills including dynamic modeling, scenario analysis, and multi-variable forecasting; familiarity with planning systems or ERP tools is a strong plus.

• Demonstrated ability to own vendor relationships at a senior level — including leading performance conversations, managing escalations, and driving supplier accountability on service level commitments.

• Track record of leading process improvement initiatives from identification through implementation, with measurable outcomes.

• Strong communicator who can translate complex inventory analysis into executive-ready narratives with clear recommendations — comfortable presenting to senior leadership and representing supply planning in high-stakes cross-functional discussions.

• Experience mentoring or developing junior team members, formally or informally.

• Comfortable operating in ambiguous, fast-evolving environments — particularly as planning systems, data infrastructure, and automation tools continue to develop.
