Job description

Senior backend engineer? Build payment infrastructure handling 150M+ API calls every month . At Dintero, you are not working on the edges of a product. You build core systems where failure has real consequences .

We develop and operate the entire platform ourselves and control the full payment flow. This gives us deep technical ownership, real responsibility, and engineers who influence architecture, not just implementation.

Dintero operates in a space that is complex in two dimensions:

Technical complexity -- distributed systems, high throughput, strict uptime requirements

Regulatory complexity -- payment schemes, compliance, auditability, and financial correctness

We are also at the forefront of innovation in the payment space:

First to implement Passkeys with Mastercard

Early adopters of real-time clearing APIs

First new acquirer in Norway in over 20 years

This is a role for engineers who want to work on serious backend systems that must work, every time .
