ONHUMAN is an AI robotics company developing autonomous general-purpose humanoid robots. Our goal is to build embodied AI systems that can perceive, reason, and act in the real world. ONHUMAN is headquartered in Madrid, Spain, and this role requires 5 days/week in-office collaboration.

Team & Role Overview

Our Operations & Finance team is responsible for tracking, structuring, and optimizing the capital flows that build humanoid autonomy. We are looking for a Cost Accountant to design and maintain the precise costing models, inventory tracking systems, and manufacturing cost structures for our hardware.

This role focuses on granular cost allocation across the entire robot lifecycle—spanning bill of materials (BOM), variance analysis, and factory floor operations—directly impacting the unit economics and scalable production of our embodied systems.

Responsibilities

• Cost Architecture & Tracking: Design and develop structured cost accounting frameworks for materials, labor, and overhead across our hardware and prototyping lines.

• BOM & Inventory Modeling: Build models to track inventory valuation, scrap rates, and work-in-progress (WIP) dynamics across the supply chain.

• Variance Analysis: Advance variance reporting approaches, including material price, usage, and efficiency alignment to keep actual costs tied to financial targets.

• Capability Optimization: Improve cost tracking accuracy in areas such as precision hardware components, specialized tooling, and long-horizon supply contracts.

• Lifecycle Cost Management: Work across the product lifecycle, from initial R&D component prototyping to full-scale assembly line deployment.

• Cross-Functional Collaboration: Collaborate closely with manufacturing, supply chain, hardware engineering, and corporate finance teams to integrate accurate cost data into the operational stack.

• Rigor & Audit Control: Design cycle counting experiments, inventory audit frameworks, and internal controls to monitor physical inventory behavior and guide process iteration.

• Paradigm Development: Contribute to the development of new cost accounting paradigms tailored to the unique assembly and manufacturing of frontier humanoid robotics.

Requirements

• Cost Accounting Experience: Experience designing and executing cost accounting models within high-growth manufacturing, hardware, or deep-tech industries.

• Modern Inventory Understanding: Strong understanding of modern inventory valuation methods (FIFO, Standard Costing), ERP systems, and warehouse operations.

• Analytical Innovation: Experience improving costing accuracy and uncovering cost-saving opportunities through operational data analysis and internal experimentation.

• Technical Proficiency: High proficiency in advanced financial modeling tools, manufacturing ERP systems (e.g., SAP, Oracle, NetSuite), and database queries/Excel.

• Experimental Rigor: Strong accounting rigor, obsessive attention to ledger accuracy, and the ability to iterate on complex data structures.

• Systems Engineering Skills: Solid process engineering skills with the ability to build reliable, maintainable, and audit-ready tracking systems.

• Autonomy & Ambiguity: Ability to operate independently and organize messy operational data into clean, actionable financial intelligence.

Bonus Qualifications

• Advanced Hardware Environment: Experience working with high-complexity hardware bills of materials (robotics, aerospace, automotive, or medical devices).

• Supply Chain Analytics: Background in raw material procurement tracking, international logistics costing, or tariff impact modeling.

• Frontier Ecosystem Familiarity: Experience working in fast-paced factory scaling environments or advanced hardware R&D prototyping labs.

• Infrastructure Costing: Familiarity with cleanroom operations, advanced tooling depreciation, or specialized high-tech assembly infrastructure.

• Professional Certification: Active certification or progress toward relevant accounting designations (e.g., CPA, CMA, or equivalent local qualifications).

Compensation

The pay offered for this position may vary based on several individual factors, including job-related knowledge, skills, and experience. The total compensation package may also include additional components/benefits depending on the specific role. This information will be shared if an employment offer is extended.
