The role

The Travel & Expenses Specialist is responsible for the day-to-day execution and control of travel and expense processes for assigned populations or regions.

The role ensures that expense claims and corporate card transactions are reviewed and processed accurately and on time, in line with company policy, applicable local requirements and financial controls. The Specialist also brings hands-on corporate travel expertise, supporting employees with air and hotel bookings and travel-related issues, and applying practical knowledge of airfare structures, fare rules and booking systems. The Specialist performs assigned corporate card reconciliation activities, maintains accurate and audit-ready records, and identifies recurring issues, risks and opportunities to improve processes and controls.

The role combines strong operational execution with employee support, financial accuracy and control discipline, helping employees travel and get reimbursed efficiently while ensuring company spend is appropriately documented, coded and controlled.

Your responsibilities will include: 

• Perform first-line review and audit of expense claims, ensuring accuracy and compliance with company policy, applicable requirements and documentation standards. Follow up on exceptions and missing information before claims progress through the approval process.
• Perform or support corporate travel bookings using the company travel booking environment and, where applicable, GDS tools, applying knowledge of airfare structures, fare rules, booking classes, routing options, ticketing conditions, changes, exchanges and cancellations.
• Support employees with corporate travel and expense queries, including air and hotel bookings, booking changes and cancellations, fare and routing questions, expense submissions, reimbursements and policy guidance. Resolve issues directly where appropriate and coordinate with travel providers or other teams for matters requiring escalation.
• Monitor corporate card transactions to ensure timely claiming, appropriate coding and clearance. Follow up on aged, unclaimed or incorrectly coded transactions and drive outstanding items to resolution.
