Cost Accountant

Cost Accountant Opportunity At Matternet

Matternet is building the future of delivery with autonomous drone networks that move critical goods faster, cleaner, and at lower cost. We work with partners across healthcare, logistics, food, and retail to deliver everything from medical items to everyday essentials, safely and reliably.

We are looking for a hands-on Cost Accountant to own the cost accounting function for our drone manufacturing operations. This role is the dedicated finance partner to Manufacturing, Supply Chain, and Purchasing responsible for the integrity of standard costs, work-in-process, production variances, and inventory valuation across both in-house assembly and subcontracted subassembly production. You will be based at our Mountain View headquarters, working day-to-day with Manufacturing, Supply Chain, and Configuration Management to make sure the numbers in SAP reflect what is actually happening on the floor.

Responsibilities:

• Own the standard cost framework in SAP Business ByDesign for raw materials, subassemblies, and finished drones, including coordinating proposed cost updates from Purchasing and Manufacturing, validating GL mapping and valuation class, and activating costs in SAP under documented sign-off
• Run and review periodic cost rolls, both annual and ad hoc (triggered by ECOs, BOM changes, or significant supplier price changes), and lead the cross-functional sense-check before activation
• Monitor and analyze production variances, distinguishing real production efficiency from standard cost drift, and partner with Manufacturing to investigate and explain unexplained variances
• Own the monthly capitalization of labor and overhead into inventory: set and maintain absorption rates, partner with Manufacturing to keep standard hours and routings accurate, and perform the monthly capitalization entry.
• Reconcile WIP, finished goods, and raw material inventory each period; ensure production orders are settled cleanly and that month-end WIP clears without ad hoc journal entries
• Support the subcontract manufacturing cost flow, including STO-based component transfers, service-only subcontracting POs, and goods receipt at standard cost, in partnership with Purchasing and the ERP/process owner
• Maintain a quarterly purchased material cost review schedule with Purchasing, and an annual full standard cost refresh aligned to the fiscal year
• Build and maintain unit cost and margin reporting that Operations and Leadership can use to make sourcing, pricing, and capacity decisions
• Support inventory cycle counts and the annual physical inventory, ensuring adjustments flow through SAP's inventory adjustment process and not through manual journal entries
• Partner with the staff accountant and Head of Finance on month-end and year-end close for all manufacturing-related accounts, and prepare schedules and walkthroughs for external auditors
• Continuously improve cost accounting documentation: SOPs, the new product introduction (NPI) cost gate, the cost change control process, and the period-end close checklist
