About the Role This is a high-visibility, high-accountability position owning the end-to-end supply planning of finished goods across a complex, fast-moving CPG environment.

Monitor and report KPIs, highlighting risks and driving corrective actions. Own and evolve planning tools, dashboards, and processes to improve visibility and efficiency. Lead or participate in cost-reduction and continuous improvement initiatives. Travel occasionally to vendors for procurement and relationship-building. Who You Are Proactive & Forward-Thinking Doesn’t wait to be told—sees what needs to be done and does it. Brings ideas, not excuses; solutions, not problems.
