Software Engineer

At Qliro we deliver safe and simple payments. We are a dedicated partner to our merchants who serve their customers every day. We believe that if our merchants grow, we grow. We are a company of dedicated, friendly and highly competent people that together have redefined what Qliro and payments can be. We are now on a journey of scaling our business both here in Sweden and the Nordics.

We are now looking for a senior Software Engineer to join STIX — our platform for credit and fraud checks. The mission of the STIX team is to protect Qliro’s payment flows through state‑of‑the‑art credit assessments and fraud detection, while ensuring a smooth customer journey and supporting Qliro’s growth ambitions.

STIX is a backend‑focused team responsible for our credit engine, integrations with credit information providers, fraud detection capabilities, and the internal fraud investigation interface used by our fraud officers. As a core part of the transactional payment path, we operate under strict requirements for speed, accuracy, uptime, and response times. (And if you’re curious about the name “STIX,” there’s a fun story involving a particular type of owl — we’ll happily share it during the interview process.)

• Processing tens of thousands of credit and fraud checks every day

• Running a containerized microservices architecture with daily production deployments

• Tech stack: C#, .NET, AWS, Docker + Swarm, Kubernetes, Microservices, Event Driven Architecture, RabbitMQ, Terraform, GitLab, MS SQL Server, DynamoDB, Redis, OpenTelemetry + Grafana, Kibana

• A mindset that values speed, correctness, and reliability, especially in microservices and event‑driven architectures

It is beneficial if you have experience from:

• Working with credit engines, credit decisioning, or similar financial decision systems

• Working with AWS or other cloud providers

• Working in a team with full platform ownership — including monitoring, infrastructure, CI/CD, and production operations
