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.

Your Profile You have experience working with complex systems in production . 5+ years of backend development experience Experience with distributed systems and architectural trade-offs Comfortable owning systems end-to-end Experience where reliability, correctness, or compliance matter Cloud experience (Preferably AWS) Scandinavian language (Norwegian, Swedish, or Danish) is a plus, but not required.

Everyone contributes to core decisions.
