Citymapper makes cities usable, helping people move through urban spaces, getting people from A to B. We’re looking for a Full Stack/Web Engineer with some backend as well as frontend experience to join our Cities Engineering Team.

Our Cities Engineering Team manages our in-house data pipeline and creates bespoke tools and applications for our data analysts. As a Full Stack/Web Engineer on the team, you will be responsible for shaping, designing and maintaining the UI for upcoming projects and existing tools.

This role covers a huge array of problem spaces; some of the things you’ll be working on:

  • Creating sophisticated internal tools to help double our number of cities
  • Participating in the discussion on what we should do with our web tech
  • Supporting other devs to help them grow in skill and knowledge
  • Ensuring the infrastructure can scale around the world

In the course of doing these things, you will:

  • Write code and tests in Javascript (React and Node.js mostly)
  • Write code and tests in Python 3
  • Deploy and support your code on AWS (We use AWS ECS for most of our tools)
  • Wrangle our webpack pipelines
  • Support and be supported by an incredibly welcoming team
  • Design and implement features of all sizes, from user authentication flow to complex bus route maps
  • 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


We need you to be smart, curious, and keen to get stuck in. Some commercial experience building full-stack apps - from infrastructure to CSS- is preferred, however we accept applications from recent grads who can demonstrate proficiency with our stack.

Our stack

  • Frontend: React (with Next.js in some places), Redux, CSS-in-JS
  • Backend: mostly Python 3 and Node.js, AWS EC2, Lambda and RDS.
  • Tooling: GitHub, yarn, webpack, AWS, SQL, Linux
  • Best practices: code reviews, tests, CI


We’re a genuinely hybrid company. Our employees have the choice of working from our headquarters on the south bank of the Thames in London, or from home (within the UK) - or a bit of both! If you’re based outside of the UK we’re also able to consider UK visa sponsorship for international candidates wanting to relocate to the UK.

  • Competitive pay & meaningful equity / stock options
  • 25 days’ annual leave plus bank holidays
  • Generous Family Leave policies for if/when you start a family
  • Free dinner in the office every day
  • Services to support your mental wellbeing
  • Cycle to work scheme
  • Pension scheme (we pay in, you pay in)
  • Conferences
  • Drinks and social events throughout the year
  • Citymapper swag
