Warehouse Supervisor

ABOUT BASE 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. ABOUT THE ROLE We’re hiring the first Warehouse Supervisor in our first major market outside of Texas. This isn’t a role where you inherit a mature operation with perfectly documented processes and years of history. You’ll help build the warehouse operation that powers Base’s expansion into Chicagoland — setting the standard for how materials move, how inventory is managed, and how the floor operates as we scale. You’ll lead hourly warehouse personnel and own day-to-day material flow in a fast-moving manufacturing environment. From receiving and storage to kitting, line-side delivery, and shipping, your team keeps production moving and prevents small problems from becoming big ones. We’re looking for someone who thrives in environments where speed matters, priorities shift quickly, and problems are solved in real time. Someone who’s just as comfortable jumping onto the floor to unblock an issue as they are reviewing KPIs and improving processes behind the scenes. The right person cares deeply about safety, urgency, precision, accountability, and building systems that actually work at scale.
