Who We Are Looking For:
We are seeking a Cost Accounting Manager to own the cost accounting function for our
metallization and separation operations. You will build and maintain our standard cost structure,
own inventory valuation and overhead allocation, and give operations leaders a clear, trusted
picture of what it actually costs us to produce.
The ideal candidate has owned cost accounting in a manufacturing environment, is as
comfortable on the production floor as in the ledger, and wants to stand up a costing model in a
business where the process itself is still being optimized.
