Our focus is to produce high-quality, working, and tested code that not only keeps us happy and productive but also helps the business to succeed. Our development process has been honed through exploring various flavors of agile and we believe that our way of working helps us get the right things done at the right time.

We’re looking for a lead backend developer to join our team; someone who has had years of experience with PHP, has seen its evolution, and understands not just how to code but how to build and architect systems using it. We’re looking for someone who has leadership tendencies, who’s passionate and driven, gets stuff done, and isn’t afraid to ask for help.

  • Collaborate with stakeholders to define technical requirements and develop technical roadmaps

  • Mentor and guide team members in their technical growth

Do you offer remote work?

You need to already be based in one of our office locations or be willing to relocate to one of them.

We have a hybrid-work policy, which means that it’s up to you whether you prefer to work onsite or feel more comfortable working from home. However, in some roles, we might be looking for people living in the same region. You can have a look at what locations we are active in via the button below.

Do you offer a relocation package and visa sponsorship?

Yes and yes.

For applicants relocating to our German or Dutch offices, we provide financial relocation assistance and step-by-step guidance to support you in your relocation journey.

We also provide visa sponsorship for our German and Dutch offices. Currently, visa sponsorship for the French office is not possible.
