Key Responsibilities

• Own the annual budgeting, quarterly forecasting, and long-range planning process for the business line, including revenue, cost of service, and margin analysis

• Track and report on key O&M/hardware operating metrics (e.g., fleet uptime, mean time to repair, cost per unit serviced, service margin by contract/customer) and connect them to financial performance

• Prepare monthly management reporting packages, including variance analysis (actuals vs budget/forecast) with clear narrative on drivers

• Support pricing and contract profitability analysis for service agreements, maintenance contracts, and warranty programs

• Build and maintain financial models to evaluate capital investments (equipment, tooling, spare parts inventory) and business cases for new service programs or geographic expansion

• Partner with Accounting on month-end close, ensuring accurate cost allocation and revenue recognition for service/maintenance contracts

• Identify cost-saving and margin-improvement opportunities across the O&M cost structure

• Develop dashboards and self-service reporting tools to give operational leaders real-time visibility into their financial performance

• Support ad hoc analyses for senior leadership, including board and investor reporting materials as needed

Qualifications

Required:

• Bachelor's degree in Finance, Accounting, Economics, or related field

• 7-10 years of progressive FP&A or corporate finance experience

• Experience supporting a hardware, equipment, industrials, field services, or asset-intensive business (O&M, install base, or service organizations strongly preferred)

• Strong financial modeling skills (advanced Excel required; experience building models from scratch)

• Experience with budgeting/forecasting tools and ERP systems

• Ability to translate operational/technical metrics into financial insights for non-finance stakeholders

• Strong communication skills; comfortable presenting to senior operational and finance leadership

Preferred:

• MBA or CFA a plus, not required
