About The Position

ON.energy is creating a new position within Accounting to own inventory accounting and controls across the full inventory lifecycle for spare parts and equipment held in a consolidated pool in Mission Critical LLC. The inventory supports project delivery and commissioning, first-year warranty, long-term service agreements, and direct spare-part sales. Inventory is relieved against an approved work order and charged to the relevant WBS, business unit, and account. The role reports to the US Accounting Director, with a dotted line to the inventory policy owner in Finance during the build, and has a standing seat on the Inventory Governance Committee. The position works daily with Commissioning, Field Services, Procurement & Supply Chain, Project Delivery, and IT. Its first year focuses on building policies, processes, systems, and controls; the ongoing focus is maintaining control and accurate accounting. The manager will co-lead the corporate inventory policy and create supporting procedures, build and govern a consolidated item master, participate in NetSuite configuration and control testing, maintain documentation for every inventory location, and oversee counts and variance investigations. The role owns monthly, location-level reconciliation of the inventory subledger to the general ledger, prepares inventory accounting entries and reporting, and supports audits and internal reviews. It also ensures transactions are documented and inventory is correctly valued, assigned, reconciled, and reflected in the books.
