Portfolio Analyst

Aar Data Analyst

Trinity Industries is seeking an AAR Analyst based out of our Dallas, TX office. The AAR Analyst 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.

What You'll Do:

• Process ownership & invoice decisions: 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.
• Disputes, CBA & exceptions: 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.
• Counterparty communications: Draft and manage exception letters and dispute correspondence; maintain a contact matrix/playbook with escalation paths and common dispute themes.
• Analysis, reporting & controls: 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.

Qualifications:

Bachelor's Degree 5 years of relevant experience in one or more of the following: AAR repair billing, Railcar maintenance, Fleet maintenance, Lease repair accounting, Railroad mechanical operations, or Car accounting or billing dispute administration Experience interpreting maintenance or operational scenarios and translating them into billing decisions.

Ability to manage multiple open issues across railroads, agents, and internal stakeholders. Ability to work cross-functionally with Fleet Operations, Finance, AR/Billing, and leadership. Direct experience with AAR Office Manual Rule 111/112/113 and CRB workflows. 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.
