• Operational Finance Partnership: Collaborate with operations and project teams to support cost control, turnaround execution, and resource optimization
• Accounting Operations Management: Oversee accounts payable (AP), accounts receivable (AR), cash management, accruals, fixed assets, and cost allocations
• Internal Controls & Compliance: Establish and maintain strong internal controls; ensure compliance with audits, tax regulations (sales, use, property tax), and reporting requirements
• Cash Flow & Balance Sheet Management: Provide visibility into cash flow, working capital, and balance sheet performance
• Reporting & Metrics: Deliver key business metrics (utilization, project performance, BRT reporting) to drive leadership decisions
• Process Improvement: Identify and implement process improvements within ERP systems and financial workflows

Qualifications

• Bachelor’s degree in accounting or finance
• 5+ years of progressive experience in accounting, financial reporting, and financial analysis
• Strong knowledge of GAAP, month-end close, and internal controls
• Experience with ERP systems and advanced Microsoft Excel skills
• Knowledge of sales tax, use tax, and property tax compliance
• Ability to translate financial data into actionable business insights
• Strong communication skills with the ability to partner across operations and leadership
• Experience in manufacturing, construction, industrial services, or turnaround environments preferred
