At the forefront of companies committed to a greener future, Alstom develops and markets mobility solutions that provide the sustainable foundations for the future of transport. Our product portfolio ranges from high-speed trains, metros, monorails and trams to integrated systems, bespoke services, infrastructure, signalling and digital mobility solutions. Joining us means joining a caring, responsible and innovative company of more than 80,000 colleagues worldwide.
We are looking for a full-time intern for a 6-month placement starting in September 2026, to join our Customs teams at Alstom Group headquarters in Saint-Ouen-sur-Seine (93 – Seine-Saint-Denis). You will contribute to the roll-out of procedures and tools that enable us to declare and track our products more effectively when exporting and importing. You will interface with around one hundred contacts based across all regions of the world; this position will give you an international-facing experience while developing your knowledge of our products and customs regulations.
Your future role
You will work within the Group Tax & Customs team, reporting to the Customs Data Manager. On a day-to-day basis, you will work closely with central and local teams, in particular customs focal points, technical teams and users of customs management tools. You will help optimise customs classification processes and provide operational support for customs management tools, while developing innovative solutions to improve the overall performance of the customs function (SAP ERP, MDM database management tool, Business Intelligence, deployment of AI as business support for identifying customs classification anomalies, etc.).
We will call on you to:
Internship success indicators: number of customs classifications recorded; reduction of, or justification for, customs classification discrepancies between two countries for the same product; number of system defects and average resolution time; number of users trained; time saved through automation.
Your profile
We value passion and mindset more than experience. That’s why we do not expect you to have every single skill. Instead, we have listed those that we believe will help you succeed and thrive in this role:
We will train you in the basics of customs practices applicable in an international industrial services company (the three pillars of the customs declaration, goods status, customs procedures).
You don’t need to be a train enthusiast to thrive with us. We can assure you that when you step onto one of our trains with your friends or family, you’ll feel proud. If you are ready to take on the challenge, we would love to hear from you!
