What We Do At Qliro

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.

What Your Team Does

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

What We Are Looking For

Experience in modernizing and migrating legacy systems
Practical experience with agile engineering methods and solid software engineering best practices
Strong understanding of system design, data structures, and API development
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
