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.
