Front-end Developer

Front-end Developer with Backend Experience

We are looking for a Front-end Developer who also has some experience with backend development in Java. You are looking for a place where your code makes the difference. At Senfal we are continuously in development and you will be influencing this. You love the newest programming languages and techniques. You also like to make a translation from data to visuals and back and thereby optimizing the frontend visuality of the software!

About Senfal and our Dream

Senfal is a tech company with an explicit dream: a clean world based on sustainable energy. We realize this dream by making smart software. We predict energy prices and purchase energy automatically. We also control devices to let them use green energy instead of grey energy. As a result, energy can be used when there is green energy available. Therefore you can save on energy costs and CO2-emissions.

Our company is growing fast and we attract motivated people. It is important that every employee bears our culture and lives by our three core values: ‘Be a beautiful nerd’, ‘Make your momma proud’ and ‘Rappo Klappo’. These core values, our personal mission, make who we are. It is our ambition to wake up every day again and serve our clients and partners with full persuasion in the most passionate, kind and efficient way.

Are these your Talents?

Besides some knowledge of Java we are looking for someone who loves:

  • Creating good-looking user-friendly user interfaces;
  • A bit of back-end programming using microservices;
  • Knowledge of HTML and (S)CSS;
  • Tight code and communication;
  • Experience with Vaadin is not a requirement but would be beneficial.

We create our user interfaces with Vaadin, a Java-based rich Internet application framework that is quite different from Javascript-based front-end development.

Do you Recognise yourself in this Profile?

  • You are a fast learner;
  • You are enthusiastic about difficult issues;
  • You are an independent team player;
  • You have interest in green energy and smart technology;
  • If you speak Dutch would be beneficial.

Our Offer:

  • A great team;
  • Work with the newest technologies and techniques;
  • Nearly unlimited growth possibilities: the better work you do, the more responsibilities you get;
  • The possibility to contribute to a fast growing organisation;
  • A cutting edge product to take care of;
  • The possibility to work and improve on our tech-stack of Java 8, Maven SCSS, ActiveMQ, JSON, jUnit, MySQL, InfluxDB, Tomcat, ServiceMix, Vaadin and many other technologies.
