About The Position

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.

Requirements

Bachelor's degree in Accounting, Finance, or related field
4+ years of cost accounting experience in a manufacturing environment with multi-level BOMs (raw material → subassembly → finished good)
Strong working knowledge of standard costing, WIP accounting, production order settlement, and inventory valuation under US GAAP
Hands-on experience with an integrated ERP system (SAP, Oracle, NetSuite, Microsoft Dynamics, or similar), including the manufacturing and inventory modules
Experience capitalizing manufacturing labor and overhead into inventory under US GAAP, including setting absorption rates and analyzing absorption variances.
Comfort working directly with Manufacturing, Supply Chain, and Purchasing teams to gather inputs (labor rates, routings, overhead, vendor pricing) and translate them into accurate standard costs
Demonstrated ability to investigate and explain production variances, and to distinguish standard cost drift from real operational performance
Strong Excel skills and the ability to build clear cost and margin analyses for non-finance audiences
Excellent attention to detail and a control mindset — you naturally separate "who proposes" from "who approves" and document your work

Nice To Haves

SAP Business ByDesign experience, particularly with Production Models, BOMs, transport lanes, and production order settlement
Experience supporting subcontract / contract manufacturing flows, including service POs and stock transfer orders
Background in hardware, robotics, aerospace, medical device, or other complex manufacturing environments
CPA, CMA, or progress toward either
Experience preparing for and supporting external audits at a venture-backed or pre-IPO company
Familiarity with PLM and ECO processes and how they tie back to ERP material masters and standard costs

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
