Sr. Material Planner

Antora Energy delivers affordable, reliable energy to industry, data centers, and the grid. Our thermal batteries turn low-cost electricity into always-on heat and power, without supply-constrained critical minerals or multi-year construction timelines.

We are growing our company with people who put team and mission first, value connection through laughter and joy, and work with humility and openness. We are committed to building a diverse, passionate, and creative team dedicated to a future powered by abundant, clean, low-cost energy.

Position Summary

As a Sr. Material Planner, you will be the hands-on owner of day-to-day material readiness—from maintaining MRP data integrity to coordinating with suppliers and supporting the production floor in real time. Your accuracy and sense of urgency will keep our master production schedule on track and our thermal-battery builds flowing. At the senior level, you will also shape planning processes, mentor team members, and drive cross-functional improvement initiatives that scale with our growth. You will report to the Material Planning Manager and collaborate closely with Production, Warehouse, Engineering, and Procurement teams.
