Job summary

General Matter seeks an experienced Supply Planner in California to build and run planning processes from the ground up. You will work with sourcing to place orders, close gaps with suppliers, and ensure on-time delivery by shaping the plan and purchasing actions.

You will maintain data integrity, run line-of-balance views, and participate in ERP/MES implementation. This role requires strong engineering or technical background and the ability to obtain security clearance.

Qualifications

• 5+ years in supply planning, material planning, or procurement for a manufacturing or hardware program.
• Hands-on experience running MRP in an ERP system, with strong spreadsheet and data analysis skills.
• Bachelor’s degree in engineering, business, supply chain, or a related technical field.
• Hands-on procurement experience: creating purchase orders, working with suppliers on quotes, lead times, and delivery dates, and expediting to get material delivered.
• Exacting with data, persistent with suppliers, and calm when the schedule changes underneath you.
• Ability to obtain and maintain any required security clearance and access authorization.

Responsibilities

• Set the planning playbook. Put supply and material planning best practices in place, from planning cadence and system parameters to data rules, then run them week after week.
• Know where every part stands. Build line of balance views that show what is on hand, on order, and still needed against demand, so gaps show up early, and extend long‑lead or single‑source exposure to the Global Supply Manager.
• Turn plan changes into purchase actions. When demand or schedules move, re-plan quickly and convert the change into purchase requisitions, pull‑ins, or pushouts.
• Carry orders through to delivery. Issue and manage purchase orders, request quotes, confirm dates and quantities with suppliers, expedite late parts, and resolve receiving and invoice discrepancies alongside the rest of the supply chain team.
• Keep stock right-sized. Set safety stock and reorder points and manage stocked SKUs, so common items are on the shelf without tying up cash.
• Be the planner’s voice in our systems. Support the ERP/MES implementation and make sure the data, parameters, and workflows fit how we operate.
• Forecast the spend. Project hardware spend from the build plan and stand up the S&OP process that ties supply, finance, and production to one plan.
