Senior Material Planner

Base is America’s next-generation power company. We’re rebuilding the foundation of modern civilization–electricity–by deploying a vast network of distributed batteries that is transforming today’s fragile, centralized grid into a resilient and abundant system. We are engineers, operators, and creatives solving some of the most complex, interdisciplinary challenges of our time.

As a Senior Material Planner at Base, you will own material availability for critical components and assemblies across our manufacturing operations. You’ll translate production plans and engineering changes into reliable supply plans, hold suppliers accountable to delivery commitments, and balance production needs with inventory and cost.

This is a hands-on role that goes beyond releasing purchase orders and chasing shortages. You’ll identify constraints before they reach the line, make decisions when supply or schedules change, and build planning tools and processes that support growing production. You’ll work closely with Manufacturing, Engineering, Procurement, Quality, Logistics, and Finance to keep materials - and production - moving.
