Senior Backend Engineer
About Fairlo
For too long, people have been trapped in financial services designed to confuse - with hidden fees, rigid terms, and fine print that works against them. This has created cycles of debt and frustration instead of offering real support.
Fairlo exists to rewrite that story - building financial services that are transparent, flexible and designed to give people control, not take it away.
Since launch, we’ve helped thousands of customers solve temporary cashflow needs in real-time at rates that consistently beat banks & credit card providers. Powered by technology, our services are automated, easy to use, and built on transparency and fairness - no fine print, no nasty surprises.
As Fairlo grows, technology is becoming even more central to our mission: scaling our platform, launching new products, and ensuring reliability and security at every step. That’s why we’re now looking for more talented engineers to join the Fairlo Tech Hub in Heraklion.
Here, you’ll work with a diverse team fully integrated with product development in Sweden. When joining Fairlo, you can be sure you're joining a company investing deeply in people, technology, and community, and you will have the chance to contribute directly to building one of the most exciting and respected tech hubs in Europe.

In this role, you will work together with a passionate team in shaping the future of our core services and your work will involve:
Build and maintain core services - from designing APIs to implementing integrations with AWS and third-party providers.
Own the full development cycle - from requirements and architecture to coding, testing, deployment, and monitoring.
Ensure quality and scalability - keeping systems reliable, secure, and built to handle growth.
Collaborate across functions - work closely with product, design, and other engineers to deliver user value quickly and iteratively.
Continuously improve - challenge solutions, explore new technologies, and bring fresh ideas to keep Fairlo’s platform evolving.
