Position Summary

As a Buyer/Planner, you will be the hands-on owner of day-to-day material readiness—supporting general planning execution, responding quickly to ad-hoc shortages, and ensuring smooth production flow. This is a generalist role across planning + procurement execution: you’ll keep MRP signals clean, coordinate with suppliers, and partner closely with Production, Warehouse, Engineering, and Procurement to keep thermal-battery builds moving. You will report to the Material Planning Manager.

Roles & Responsibilities

General Planning Execution

• Own daily planning execution to keep builds on track (supply coverage checks, MRP follow-ups, PO status tracking, material readiness reviews).
• Maintain planning routines and drive timely actions across internal teams and suppliers as priorities shift (schedule changes, high-mix updates, urgent gaps).
• Support day-to-day NetSuite/MRP execution by maintaining key planning parameters (lead times, safety stock, UoM, cost, part ownership) and resolving planning signal issues.

Investigate inaccurate PO suggestions or shortage signals, identify root causes, and implement corrections to prevent recurrence. Ad-hoc Shortage Response

• Serve as first responder to material shortages impacting production/testing; drive containment actions and recovery plans.
• Partner cross-functionally (Production/Warehouse/Engineering) to confirm root cause (system vs. physical vs. supplier) and define immediate workarounds.
• Provide clear, timely updates on ETAs, recovery actions, and risks; align stakeholders on next steps.
• Support material readiness improvements, including kitting checks, line-side min/max reviews, and cycle count support as needed.

Procurement & Supplier Performance

• Place POs to support inventory and equipment requirements for operations.
• Collaborate with Design Engineering to understand requirements and communicate design changes to suppliers.
• Negotiate terms as needed to secure pricing, lead times, and quality commitments.
• Monitor supplier performance and drive improvements in delivery, quality, and responsiveness.

Key Qualifications

• Bachelor’s degree in Supply Chain, Business, Engineering, or a related field (or equivalent experience).
• 3+ years in purchasing or material planning.
• Ability to work onsite 5 days per week.
• Proven ability to multitask, handle ad-hoc requests, and prioritize effectively in a dynamic environment.
• Growth-oriented, eager to learn, share knowledge, and iterate on processes.
• Clear communicator—able to translate data into actionable insights for technical and non-technical audiences.

Additional Qualifications Desired

• Hands-on experience with an integrated MRP/ERP system (NetSuite, SAP, Oracle, etc.).
• Generalist mindset (comfortable owning a broad range of tasks vs. specializing in one area).
• Experience in a startup or similarly fast-paced environment where work may be new, ambiguous, and evolving.
• Experience in manufacturing and/or warehouse operations.
• Experience with AI/BI tools for reporting and analysis (dashboards, trackers, workflow automation).
