Citymapper makes cities usable, helping people move through our urban spaces, getting people from A to B.

Citymapper Pass is a natural next step for the world’s best transport app - solving ticketing. Urban mobility is changing and Pass offers a weekly subscription covering all modes of transport in a city; simplifying booking and payment across public and private transit.

You will help us build better user experiences around paying for your daily commute, scale and secure infrastructure for a growing user base, explore the byzantine charging patterns of TfL, and help expand Pass to a global audience.

This role means trying to answer questions like:

  • What could be better about paying for the tube every day?
  • How can we programmatically enforce a consistent transaction ledger?
  • How do we make sure payments always succeed?
  • Can we drive a change in behaviour when the user is not in the app?
  • What’s a sensible infrastructure where determinism is more important than latency?
  • How do we ship quickly without compromising on reliability and predictability?
  • Is get-me-home green better than hot coral?

Whether you are junior, senior, or Margaret Hamilton, you will:

  • Write Python 3 code and tests
  • Deploy and support your code on AWS
  • Support and be supported by an incredibly welcoming team
  • Design and implement features of all sizes, from a blinking home screen indicator to a Payment Services Directive 2 compliant user authentication flow
  • Work side-by-side with talented software engineers, product designers, data scientists, and customer support operatives on a day-to-day basis
  • Learn and grow at a dizzying pace
  • Teach us how to be better
  • Citymapper’s main office is in London, and we also support hybrid and remote work within the UK.
