Location: Oslo

Your Headway is recruiting for Dintero.

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 .

Production at Scale

150M+ API calls per month

10 senior engineers -- small team, high ownership

Infrastructure designed for high availability and robust transaction flows

What You Will Work On

Design and own backend services end-to-end

Build APIs used directly by merchants and partners

Make architectural decisions with long-term impact

Work with scalability, observability, and operational quality

Ship to production frequently and take ownership of what you build

In short: less coordination, more engineering.

Tech Stack

Deliberate choices. Minimal hype.

Infrastructure as Code

API-first

We value sound engineering decisions over chasing trends.

This Role Is Likely Not Right If You

Prefer frontend-focused work

Want heavy processes and multiple decision layers

Prefer narrowly defined tasks over ownership

We are intentionally a small team. Everyone contributes to core decisions.
