Back-end Developer (NL/EN)
#LI-DNI
Help build the systems that serve millions of customers
At Gomibo, we do almost everything in-house—from payments and logistics to warehousing and our product catalog. Our backend systems make all of that possible. As a Junior Backend Engineer (Software Engineer I), you'll be writing production code from the start—working on real features, fixing bugs, and improving the systems that power our platform in over 30 European countries.
You'll contribute independently to well-scoped tasks while developing a deeper understanding of our architecture and tooling. Experienced teammates are there to support you, but we expect you to take initiative, write reliable code, and ask smart questions when things get tricky.
