What is a Product Manager at Transport for London?

As a Product Manager at Transport for London (TfL), you sit at the heart of one of the world’s most complex and iconic transport networks. Your work directly impacts the daily lives of millions of Londoners, ensuring that the digital products powering the city—from journey planning tools to payment systems—are seamless, reliable, and user-centric.
