Do you want to save the world?

No, we’re not hiring superheroes (and anyway, lycra in the workplace would be an HR nightmare).

We’re talking about the climate crisis, which we believe needs to be stopped. Like, NOW. Not tomorrow (procrastinators need not apply).

Not only that, but we think we’ve found a way to do it…

We are building a way for anyone to invest in companies and other financial assets that are taking climate change seriously and showing measurable results. The way to do this is an efficient way of combining impact calculation, financial expertise, transparent communication and technology. And that is why we’re looking for a talented Full Stack Developer to join our growing team and help us with our mission.


  • Want to work in a company that is doing big things and offering impactful work

  • Passionate about stopping climate change

  • Able to deliver high-quality work in a fast-paced start-up environment

The role:

  • Work with a small but talented team of developers and designers to turn an exciting (and pretty grand) climate impact concept into reality in the form of a fully functional native mobile app and cross-platform service.

  • The chance to step into a senior development role. So, you’ve got skills you want to show off? Great, because we need you to not only build integrations into 3rd party services but our microservices as well. And on top of that, you will make daily contributions through design, development and QA.

  • Take responsibility for day-to-day production support. We need things to run smoothly and we need you to make that happen.

  • Create and maintain technical and functional documentation — you know what you’re doing, help make sure others do too.

  • Show us cool stuff. That can mean following (and highlighting) emerging tech trends or showing off development best practices — anything to help make our digital solutions shine.

Your skills:

  • You have experience in building B2C applications launched successfully for large customer base with React Native
  • You're right at home with the cloud, web backends and building elegant APIs.

  • You have always been a bit curious about how things work under the hood. You can position yourself in the role of a backend developer, cloud specialist or somewhere in-between.

  • Several years of professional experience, ideally in the full-stack development of web-based and mobile software applications, as well as CICD.

  • Experience working with agile software development methods (e.g. Scrum, Kanban).

  • An architecture-level understanding of software design, with experience of implementing multi-layer services.

  • A good understanding of one or more cloud platforms, scalability, serverless architectures and an understanding of the benefits/drawbacks of microservices.

  • Experience in designing and implementing modern GraphQL or REST-based APIs.

  • A solid understanding of relational database, no-SQL databases and approaches of data engineering.

  • Broad knowledge of the tools, frameworks and technologies related to designing, implementing, deploying and hosting software services.

  • Strong analytical skills.

  • Excellent communication skills that enable you to collaborate with and motivate people of various skills and backgrounds.
  • ideally but not necessary previous experience in a fintech company 

What we offer:

  • A project with a real and measurable positive impact on the world.

  • A new way of looking at, and tackling, the climate crisis.

  • An experienced and enthusiastic team ⁠— we’re small but mighty with experts from the start-up world, financial industry and the front-line of the sustainability fight.

  • Nordic roots and a Nordic way of working, which means a belief in work-life balance and flexible working.

What we stand for:

  • We are authentic and fully transparent.

  • We do things differently.

  • We want to leave the world a better place than we found it.

  • We are hopeful.
