Generalmatter Supply Planner at Generalmatter builds and runs supply and material planning processes to ensure parts arrive on schedule. The role involves managing purchase orders, forecasting spend, and supporting ERP/MES implementation.

Responsibilities

Every program runs on parts arriving when they are scheduled. As Supply Planner, you turn shifting demand into a plan we can trust: what we need, when we need it, and what to order today to get there. You will build the planning processes from the ground up, run them yourself, and work hand in hand with sourcing to place orders and close gaps with suppliers. If you want to be the person the whole team relies on to know what is coming next, this is the seat.
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 escalate 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.
