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 doesWe 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.

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.)
