About The Position

Trinity Industries is seeking an AAR Administrator based out of our Dallas, TX office. The AAR Administrator will be the primary business owner for Trinity’s insourced AAR repair billing and counter-billing process. This role is responsible for the day-to-day execution of AAR invoice review, Counter Billing Authority (CBA) administration, exception handling, railroad and agent communications, and monthly follow-through on disputed and accepted claims.
The AAR Administrator applies AAR billing knowledge, maintenance judgment, and strong written communication to identify improper charges, manage disputes, and drive recovery through closeout—supporting a durable in-house capability for AAR billing oversight.
This is a process-owner role focused on exception management, counterparty communication, and recovery execution—not primarily clerical or file ingestion.

• Experience interpreting maintenance or operational scenarios and translating them into billing decisions.
• Strong written communication skills, especially for formal business correspondence and dispute documentation.

• Ability to work cross-functionally with Fleet Operations, Finance, AR/Billing, and leadership.

• Prior experience handling exception letters, rebuttals, resubmittals, or counter-billing disputes.
• Prior experience in railcar maintenance, repair validation, or component history review.
• Experience working directly with railroads, railroad agents, contract shops, or running repair agents.
• Familiarity with lease pass-through billing, reimbursable repair billing, or customer credit processes.
• Experience with case tracking, workflow tools, ERP systems, or rail billing systems.

Responsibilities

• Own day-to-day administration of the AAR repair billing/counter-billing workflow; review invoices and determine pay, dispute, reject, exception, or escalation in alignment with Trinity policy and AAR rules.
• Manage the lifecycle of disputes, CBA actions, and exception claims from identification through closeout; ensure proper support, documentation, tracking, and timely follow-up on aged/open items.
• Draft and manage exception letters and dispute correspondence; maintain a contact matrix/playbook with escalation paths and common dispute themes.
• Identify recurring billing issues and root causes (pricing, job codes, responsibility, duplicates, missing support, maintenance history); maintain records, templates, work instructions, and KPI reporting to drive continuous improvement.
• Partner with Finance and internal stakeholders to support credits/rebills for accepted items and ensure clean monthly closeout.
