digitize the telecom industry. Our platform powers next-generation
mobile providers, from traditional MVNOs to eSIM challengers and
non-telecom players looking to embed connectivity into their
offerings. With our roots in Stockholm (Sweden) and our sights on a
global scale, we're building the future of telecom—fast, adaptable,
and customer-first. As we expand into the Americas, we're looking
for a Senior Software Engineer based in Spain or LATAM, working US
