Sourcelabs is a high-quality consultancy company that was founded for developers by developers. We believe that happy developers make a high impact. That's why we value a good work-life balance, support employee vitality, and invest a lot in professional development and growth.

Our clients appreciate our deep expertise and know they can count on us to tackle complex and technically challenging projects. How? Because we keep being curious, we question the status quo and we keep investing in our technical skills. It's during Sourcelabs internal meetups that we experimented with new technologies like Dapr, GraphQL, Serverless, Kafka, Machine Learning, Game Development, creating your own Chrome extension, or (yep) working with 'no code' platforms. Because… why not? We constantly want to learn and grow - maybe on the next project one of these technologies will be used.

We are one of the proud Community Sponsors of the Dutch Kotlin User Group ( - we believe in Kotlin since its beginning and we support developers by organizing Kotlin workshops, meetups, and trainings.

It’s up to you to tell us what kind of project will make you happy!
  • Build your personal development plan together with Jarno and Stephan (certifications, trainings, conferences)
  • Work on own projects ½ day per month during the internal ‘half meetup day’
  • Prepare or participate in the monthly internal meetups with a focus on a technical challenge ( every last Friday of the month
  • Challenge Sourcelabs colleagues at FIFA, scrabble, padel, and water skiing (to name a few examples) during quarterly outings

What you will bring:

  • At least 3 - 5 years of experience as a software engineer within the Java ecosystem
  • Solid Software Engineering basis backed up with a degree: Bachelor or Master
