Senior Back-end developer at Connected Cars

Connected Cars is working on an ambitious project to connect 1,000,000+ car-owners with their vehicles by hooking into the on-board diagnostics available in every modern car. Currently, we have Volkswagen, SEAT, ŠKODA and Audi on board in Denmark and are looking abroad. Our team consists of around 40 people from different backgrounds, such as design, engineering, data science, mechanic, management consulting, marketing, support etc.

The position

We are currently using Node.js, MySQL and BigQuery on the backend, React on web and React Native for our mobile apps on iOS and Android. On the hosting side we are using Google Cloud with Kubernetes and Docker, but our tech stack is continually evolving and we are always looking to do things better.

We believe in release early, release often which is why we currently run many daily releases using our continuous integration and deployment setup.

Developers work closely with product and design in small teams of about 3-4 people each. We focus on minimal overhead and bureaucracy as we want to ensure independence and decision power stay within the teams. This means that teams have a lot of influence on how they work, what they focus on and how they deliver new features and functionality.

As a back-end developer at Connected Cars you will mainly be working with our API’s and backend applications make sure they can scale to handle the very large data sets we are working with. You will be responsible for moving your own code into production.

What we like

It’s not important that you know every part of our current tech stack or that you have years of experience in JavaScript and Node.js. Most important is that you have experience as a developer and that you like to learn new things and know how to leverage your experience across technology stacks and languages.

But here is what would be a good fit:

  • Experience in more than one technology stack
  • RESTful/GraphQL APIs in Node.js, Go or similar
  • MySQL, PostgreSQL or similar
  • JavaScript, TypeScript or similar
  • Dependency management tools like Yarn or npm
  • Continuous integration and test driven development
  • Focus on quality and doing things right
  • Working with large data sets (terabytes)


  • Candidate codes in his/her spare time
  • GitHub or similar account with sample code
  • Open Source development experience

What is in it for you?

  • Be part of a journey to develop the car owner experience of the future
  • Highly skilled co-workers to learn from
  • Competitive salary and pension scheme
  • Flexible working hours and location
  • Company car package (configure a brand new car every six months)
  • Employee discounts on cars (incl. leases and repairs) for yourself and your family
  • Laptop of your choice
  • Cheap lunch scheme
  • All the snacks and sodas you can consume
  • Great beers on Fridays (and yes, we’re open to suggestions)
  • Strong Open Source commitment
