Senior Accounting Specialist

J National Contractors | Dallas, TX | Full-Time, In-Office


About J National Contractors


J National Contractors is a growing, multi-location commercial service and construction company headquartered in Dallas, with operations in Houston and San Antonio. We provide plumbing, HVAC, electrical, roofing, restoration, and construction services.


We are looking for a sharp, highly organized, and resourceful Senior Accounting Specialist to join our Dallas accounting team.


Position Overview


We are looking for an accounting problem-solver — someone who enjoys digging into numbers, finding discrepancies, organizing financial information, and making sure everything adds up.


This is a hands-on accounting position, not a management role. The ideal candidate is analytical, detail-oriented, comfortable working independently, and thrives in a fast-paced environment where priorities can shift.


We need someone who doesn't just process transactions but understands what they're looking at, asks the right questions, and takes initiative to resolve issues.

• Research and resolve discrepancies, unmatched transactions, and accounting inconsistencies.
  
  
• Assist with month-end closing and financial reporting.
  
  
• Review financial transactions for accuracy, proper coding, and supporting documentation.
  
  
• Maintain accurate and organized accounting records.
  
  

Accounts Receivable & Accounts Payable

• Investigate billing discrepancies and unapplied payments.
  
  
• Review vendor invoices, statements, and payment records for accuracy.
  
  
• Identify duplicate charges, missing invoices, and incorrect allocations.
  
  
• Support the accounting team with AP and AR reporting and account cleanup.
  
  

Job Costing & Operational Accounting

• Review labor, materials, subcontractor expenses, and other job-related costs.
  
  
• Help ensure expenses are accurately allocated to the correct jobs and locations.
  
  
• Investigate discrepancies between operational records and accounting systems.
  
  
• Work with internal departments to obtain missing information and resolve accounting issues.
  
  

Reporting & Process Improvement

• Prepare and maintain Excel spreadsheets, reconciliations, and accounting reports.
  
  
• Assist with identifying accounting errors, inefficiencies, and opportunities for improvement.
  
  
• Help streamline accounting processes and improve accuracy.
  
  
• Support accounting workflows and data accuracy as the company transitions to ServiceTitan.
  
  
• Take ownership of assigned accounting projects and follow through to resolution.
  
  

Qualifications

• 3–5+ years of hands-on accounting experience.
  
  
• Strong understanding of general ledger accounting, AP, AR, and reconciliations.
  
  
• Excellent Excel skills, including pivot tables, lookups, and working with large datasets.
  
  
• Experience with QuickBooks or similar accounting software.
  
  
• Strong analytical and problem-solving abilities.
  
  
• Exceptional attention to detail and organizational skills.
  
  
• Ability to prioritize multiple tasks and meet deadlines.
  
  
• Comfortable researching and resolving accounting discrepancies independently.
  
  
• Experience in construction, contracting, or service-based businesses is a plus.
  
  
• ServiceTitan experience is a plus but not required.
