Skilled RoR backend developer to join sustainable mobility startup

Donkey Republic Copenhagen Full-time
Salary Competitive
At Donkey Republic we believe that sustainable mobility should be available to everyone. We do this by providing an affordable bike rental service across Europe in more than 60 cities. We work closely with cities and lawmakers to help transform cities into more liveable places.

What your job will be

You will team up with our product team which today comprises 7 developers, a designer, a Product Owner and a CTO. You will join a group of two very skilled backend developers that work with everything from connecting our e-bikes and e-scooter to the platform to our fleet management tool and bike service backend which is the backbone of our system. You will take an equal part in solving all challenges big and small that we face.


Who you are

We expect you to have years of experience with building services using the Ruby on Rails framework. You should be self-driven enough to drive the development of the backend forward, while also caring about the overall performance of the team.

We cherish virtues like code reviews, consistency and code conventions and have a big setup of tools to help lint and test our code in any way.

Here we would usually write a technical stack that we would want you to have experience with, but the truth is that we want you to be well structured in your code, take responsibility for what you do and want to constantly improve your already great coding skills. And most of all, we want you to be motivated by working in a social team with the ambition to do the best they can.


Here’s some of the technologies we work with:

  • PostgreSQL

  • Vue.js

  • RSpec

  • Heroku - We are hosted on Heroku

  • MQTT

  • And much more


What we offer

A spot in the team of an inspiring international startup, currently growing at a pace that not even we can fully grasp. A job where achieving our vision is as important as creating a bright future for each team member.

We enjoy mindful risk-taking, experimenting with features, getting things done fast and seeing the results of our daily work out there in the real world, where we ultimately help people move easier and explore better - on two wheels.
