Job description

Felyx is expanding! The coming years we are facing hyper-growth in The Netherlands and the rest of Europe. Therefore, we are looking for ambitious Full Stack Developers to build our new technological architecture, the foundation of the company, together with the Lead Developer. 

We are a young and driven scale-up, with our innovative and sustainable tech platform, we are making swift door-to-door transportation the new status quo.

Do you want to make social impact on urban mobility and drive change? Plus, you share the same DNA: self-starter, social, driven and values based on integrity. Great! We want you!

Here's the challenge

Currently, we are primarily working with Ruby (on Rails), but we care much more about general engineering skills, than about knowledge of specific programming languages or frameworks. Our ideal candidate enjoys working on both the front-end and back-end parts of any piece of software.

We are building up a new team of 5-6 developers of which you will be a part.


We get truly excited if you

  • Have past experience in designing and building large-scale systems with reliability and maintainability in mind 
  • Master at least two of the following languages: Go, Ruby, Java, Python, Node
  • Are interested in building out your Go knowledge
  • Enjoy being a generalist working across the entire stack 
  • Are uncomfortable shipping code with less than 90% test coverage!
  • Have experience with various forms of automated testing (unit, functional, integration and E2E tests) 
  • Are experienced integrating and working with third party (REST) APIs 
  • Know your way around Git, Docker, AWS, Heroku, Redis, CI & CD tools 
  • Have strong abstract reasoning skills and an agile and pragmatic mindset 
  • Have excellent communication skills and are fluent in English

Bonus points if you 

  • Have experience creating mobile (iOS/Android) apps, professionally or as a hobby project 
  • Have a BS/MS degree in Computer Science or a related field
