Back-end developer (medior/senior)

What will you do?

We would like to use your extensive skills to further
develop and improve with a focus on rolling out new
features within the portal and app. You will work on: fleet management,
heatmaps, geo-fencing, maintenance plans, ETA tools,
vehicle dashboards, consumer and corporate apps (native) and platform
improvements at your own discretion. You will work a lot independently on projects
working but with specialised colleagues around you.

What do you take with you?

You have been sitting for more than 3 years full-time (as a medior and 5 years as a senior) behind the knobs as a back-end developer and knows his way around code-land flawlessly. A back-end position with a focus on optimising processes, building and implementing new services and further developing these services.

You have experience in one of the following languages:

  • Python
  • Java
  • PHP


Nice to haves are experiences with: 

  • Experience with languages: Rest / Go
  • Unit and integration testing
  • Frameworks such as NextJS, Laravel, Java Spring, Rocket and or Echo(Golang)
  • Docker
  • MySQL / NoSQL
  • Microservice archtecture 

And if you possibly don't know any of the things we are happy to teach you.

You have good communication skills, are independent and enjoy taking responsibility. We are a small, close-knit team, each with their own responsibilities and room to fulfil them independently. Passion for cycling is not a must, but it does have an edge with us.

What we offer...

A job in the world of IoT for bikes at a young and fast-growing company with national and international customers. A cool place in Rijswijk is our home base, offering an inspiring workplace and cosy environment for lunch and drinks. You are flexible in arranging your full-time job. We reward you in line with the market. You will also work on a company MacBook Pro that is entirely at your disposal. And those stories about bikes: you get them for free 🙂 .

About us

Tracefy is a company in IoT solutions for Smart Mobility vehicles. We are a team of young professionals, crazy about cycling and driven to contribute to social challenges such as sustainable mobility, quality of life, safety and health.

Cycling is number one when it comes to sustainable solutions to keep cities accessible and liveable. Look around you and you see more and more bikesharing and bicycle delivery services. Organisations that manage not 1 but an entire fleet of bikes (and e-scooters). With our GPS solution - a combination of a GPS tracker, app and online portal - we offer the possibility to set up fleet management simply and efficiently. And so using bicycles and e-scooters becomes an even more attractive alternative to cars.

A GPS tracker that sends real-time data and an online portal that automatically processes this data. There are some technical tours de force in that, even if we say so ourselves. And we want to keep developing in this. So we are looking for a software developer who can expand our fleet-management portal and app with new features to entice even more organisations to switch to a sustainable form of mobility.
