Experienced Web Developers

Loco2's mission is to make booking trains anywhere in Europe as easy and affordable as possible, from epic international adventures to everyday local commutes. Our booking coverage is unrivalled and growing.

We're looking for an experienced mobile engineer to join our growing engineering team. You will help us deliver a world-class mobile experience through our hybrid iOS app, combining fully native views with our Single Page Application (see below).

We're a small, passionate and cosmopolitan team, with a healthy remote-first culture and an office in London. Our success is built on trust, empathy and shared knowledge, with our users at the centre of what we do. We're proud to have an average rating of 9.3 out of 10 on Trustpilot after 22,000 reviews.

We’ve been selling tickets since 2012, and we’re growing rapidly as the business matures. Our goal is to scale effectively whilst continuing to delight our users.

  • Our days are not full of meetings and needless distractions, allowing others to achieve flow is a big part of supporting each other
  • Everyone is encouraged to ask questions, think creatively and suggest new working practices. We have a small team so your voice will be heard

Tech stack and role description

We’re transitioning our traditional multi-page application to a React-powered single-page application so our customers can enjoy a fast, reliable and consistent experience across all of their devices.

This role is focused on that challenge, working with experienced members of our existing team to help us separate concerns and scale effectively without succumbing to the potential pitfalls of a microservices approach.

The new front-end will use modern technologies, including React, TypeScript, Redux and modular CSS. We know React is a new technology, and we’re willing to consider anyone with demonstrable JavaScript experience and a desire to learn and grow, with Ruby experience as a nice-to-have.

Whilst we don’t expect you to be a master of the following technologies, our current software stack consists of: current mobile applications are hybrid, mixing fully native views with numerous embedded web-views, presenting 

Whilst we don’t expect you to be a master of all of the following technologies, our current software stack consists of:

  • A Ruby library for communicating with train booking APIs
  • A traditional multi-page web application written in Ruby on Rails, using CoffeeScript and SCSS
  • AWS hosted Docker infrastructure, with continuous delivery
  • A hybrid iOS app written in Swift
  • A hybrid Android app written in Kotlin


About you

An ideal candidate:

  • Has 3+ years of professional web development experience
  • Deep knowledge and experience of JavaScript, HTML and CSS, and ideally Ruby (or a similar server-side language)
  • Is excited about the future of the web platform, the ever evolving JavaScript ecosystem and is motivated to help Loco2 adopt modern front-end technologies and processes
  • Takes pride in their craft and adheres to industry best practices such as testing, code linting, peer review and clean modular maintainable code
  • Has a keen appetite for self-improvement and growth, but doesn't hesitate to ask for help when needed
  • Strives to discover and understand the root cause of problems, suggesting new and improved solutions, rather than treating the symptoms
  • Is fluent in English and confident communicating and sharing complex information and learnings with both technical and non-technical team members
  • Can work hours that have some overlap with London daytime
  • Is motivated by Loco2's mission

Unfortunately, we can currently only accept applications from within the EU (including the UK) or from candidates who already hold a valid UK working visa.


There are some specific questions we'd like you to answer (feel free to be brief if you’d prefer to elaborate in other areas):

  • What country and timezone do you live in?
  • What are your approximate salary expectations? (please state currency)


We welcome applications from everybody, regardless of race, gender, or sexual orientation.


To try to make the hiring process as fair as possible, if we are interested in your application, then you'll be asked to complete a programming challenge which is judged anonymously. We deliberately anonymise responses to this task in order to mitigate any inherent biases in this regard.


Our emphasis is on finding somebody with demonstrable skills rather than somebody who is good at self-marketing. This process helps us focus on that.
