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 Material Planner, you will be the hands-on owner of Antora's material planning function — responsible for keeping MRP signals clean, maintaining planning parameters, translating demand into a reliable supply plan, and ensuring material readiness across production, R&D, and service. This is a planning-first role (roughly 80–90% planning, 10–20% buying support): you will own the MRP engine day-to-day, drive continuous improvement in planning processes and system capabilities, and partner closely with Production, Warehouse, Engineering, Procurement, and Supply Chain Management to keep thermal-battery builds moving. You will report to the Material Planning Manager.

ROLES & RESPONSIBILITIES

MRP Execution & Planning Ownership * Own daily MRP execution in NetSuite — action exception messages, review Clear-to-Build (CTB) status, drive PO coverage and reschedule signals, and keep the planning horizon actionable. * Maintain and govern MRP planning parameters (lead times, safety stock, min/max, reorder points, lot sizes, UoM, planner/buyer codes, part ownership) with clear rationale and documented changes. * Investigate inaccurate PO suggestions, false shortages, or unexpected planning signals; identify root causes (data, parameter, BOM, timing, or supplier) and implement corrections to prevent recurrence. * Perform manual CTB analysis for critical assemblies (e.g., Block, GR1, HX) and long-lead components; escalate risks with clear recovery options. Ad-hoc Shortage Response * Partner as a planning-side responder to material shortages impacting production and testing — determine whether the root cause is system, physical, or supplier-driven, and drive containment and recovery plans. * Coordinate with Production, Warehouse, Engineering, and Procurement to confirm root cause and define immediate workarounds (alternate parts, expedites, kitting adjustments). * Provide clear, timely updates on ETAs, recovery actions, and residual risks; align stakeholders on next steps. * Monitor critical shipments and long-lead items; maintain visibility into supply risk and drive proactive mitigation. System, Project & Continuous Improvement * Bring an AI/automation mindset to repetitive planning work — identify opportunities to eliminate manual toil through tools, scripts, or workflow automation. * Build and maintain planning reports and dashboards (Hex or equivalent BI) to make supply/demand, CTB, and inventory health visible and actionable. * Support material forecast and capacity planning; align supply commitments with demand signals from Production, R&D, and Project Sites. * Place POs and support day-to-day buying execution as a backup to the buying team, particularly for parts within your planning scope.

KEY QUALIFICATIONS

* Bachelor's degree in Supply Chain, Industrial Engineering, Business, Engineering, or a related field (or equivalent experience). * 3+ years in material planning, production planning, or a similar planning-focused role in a manufacturing environment. * Hands-on experience owning MRP execution and maintaining planning parameters (safety stock, lead time, min/max, lot sizing) — not just consuming MRP output. * Demonstrated ability to investigate and resolve planning signal issues (false shortages, mis-scheduled POs, BOM/parameter data problems). * Strong analytical orientation — comfortable working with data in Excel, SQL, or BI tools to diagnose problems and inform decisions.

• Ability to work onsite 5 days per week in San Jose, CA.
• Proven ability to multitask, handle ad-hoc requests, and prioritize

effectively in a dynamic, high-mix environment. * Growth-oriented — eager to learn new tools, share knowledge, and iterate on processes. * Clear communicator — able to translate data into actionable insights for both technical and non-technical audiences.

ADDITIONAL QUALIFICATIONS DESIRED

• Hands-on experience with NetSuite MRP (or similar integrated ERP).
• Experience planning for hardware/discrete manufacturing environments with

high-mix, ramping production. * Familiarity with NPI/ECO workflows and their material planning implications (BOM changes, phase-in/phase-out, obsolescence). * Experience in a startup or similarly fast-paced environment where work may be new, ambiguous, and evolving. * Experience with AI tools for supply chain workflows (e.g., automating data pulls, exception triage, or reporting). * Some hands-on buying/procurement experience (PO placement, supplier follow-up) as a complement to planning depth.
