About Fairlo

We're a well respected Scandinavian fintech scale-up that's on a mission to outsmart the predatory credit market. Since 2018, we've been creating friendly and sustainable financial services from scratch. 

Our first service, Fairlo Everyday, is a seamless overdraft that has unshackled Swedes from unsustainable credit solutions. Since launch, our customers have replaced opaque and unpredictable loans such as credit cards and buy-now-pay-later options with Fairlo.


Some of the key features that have won Fairlo the respect of customers and peers alike are:

  • A purpose-built core banking solution allows instant withdrawals and deposits to and from the customers current account twenty-four seven—all within seconds.
  • A fully digitalised customer journey. All applications are handled end-to-end in our backend.
  • Transparent and low interest rates, for everyone, made possible by our underlying tech.

The reception we've gotten in Sweden has been humbling. More than one in ten of our customers rate us on TrustPilot, with an average score of 4.9 out of 5. In addition, we're backed by one of the Nordics' most well-known incubators – Sting, Stockholm Innovation & Growth AB – as well as Swedish state-owned Saminvest and a multitude of experienced investors.

UK expansion

However, our mission has just started. Our next big step is to bring Fairlo to the UK. So if you're keen on making a positive impact while developing the next big fintech solutions, we believe you'd enjoy the developer role at Fairlo!

  • A competitive salary and benefits package.
  • Teaming up with and learning from some of Europe's most outstanding developers.


First and foremost, we believe you share our passion for long-term positive impact. Beyond that, we believe you have a few particular skills that'll prove useful in your role as a developer at Fairlo.

We believe you've got:

  • At least 3 years of developing Node.js applications.
  • Experience with a modern backend framework (Node.js, .NET core, JAVA). Knowledge of Node.js is preferred since our backend uses this technology.
  • A few years of experience within an agile software development organisation.
  • Experience writing self-documented as well as clean and readable code with adequate test coverage.
  • Working extensively with REST standards.
  • Experience in communicating and collaborating in a professional workspace.

It'd be nice if you also have:

  • Strong knowledge of relational or non-relational database systems.
  • Experience with API documentation (Swagger/Open API).
  • Experience in TDD and other testing practices.
  • Contributed to open-source projects.
  • University and/or Postgraduate Degree in the field of Computer Science or related field of studies.

The way we work

We're a rapidly growing, dedicated team that believes in mutual respect and high aspirations. Our overarching goal is to simplify the complicated and always approach solutions asking ourselves: is this truly fair? 

We know that making digital products takes a digital company. That's why we run a distributed organisation across Europe. If you join Fairlo, you get to choose to work from our upcoming London offices, home, or, when possible, anywhere in Europe (including our offices in Stockholm and Heraklion).
