Be Part of the Future of Rail

The railway in Britain is undergoing its most significant transformation in a generation, and Rail Delivery Group (RDG) is at the heart of it. With the creation of Great British Railways (GBR), we're helping shape a new era of smarter, simpler, and more connected ticketing.

RDG's Digital Ticketing Services (DTS) team leads innovation in smart ticketing, enabling fully interoperable digital solutions across the country. Our work helps Train Operating Companies (TOCs) deliver seamless journeys for millions of customers - now and into the future.

About The Role

With the first major iteration to the ITSO Specification in years, the ITSO on Mobile project is enabling the use of mobile credentials across National Rail. This project combines the flexibility of mobile eTickets with the security and speed of NFC technology. You'll be at the forefront of this transformation, designing solutions that bring true walk-up convenience to passengers across the UK.

This role is focused on delivering the technical vision and architecture for RDG's ITSO on Mobile programme. You'll shape the end-to-end technical architecture of this programme, delivering the UK's first national mobile smart ticketing solution. You'll also line-manage our in-house ITSO expert, guiding the blend of transport standards and mobile-first thinking.

This is an ideal opportunity for someone who has worked on secure, scalable mobile platforms (such as mobile wallet, tokenisation or contactless services) and wants to apply that expertise in a transport context.
