We are a core team of 4 developers looking to expand as we expect a lot of incoming customers in the near future and already now the customer requests are so extensive that we are struggling to keep up with new feature releases.

We’re seeking brilliant backend developers to build scalable systems for client around the globe.

The job

The job is to build and scale our Fintech solution from a couple of customers to a couple of thousand in a few years.

The work will consist of:

• Reading data through APIs

• Cleaning, structuring and analyzing them

• Restructuring them for use in our front end

• Rapidly pushing them to end points

• Scaling it by a factor of a thousand

In that order

 Our tech stack is

• C#

• PostgreSQL

• Extensive use of OpenAI, Grok, Copilot etc.

• Vue

• React

• Azure

You must have solid Back-end experience, but dont need to know everything. We want problem solvers, not dictionaries; if you are smart, we can teach you whatever language or technology you need.

About you

You are incredibly smart - we can’t wait on non-smart staff! And want to learn. And you get things done.

What is in it for you

A great internship with some great people. And a chance to learn and grow as a developer and human being.

At CostBits, we give our interns a lot of responsibility from day 1 and see how they handle it. You might get to interview new candidates. Or you might design the next database version. Something you would never be able to do in a big company. In addition, we will teach you about priorities, communication, collaboration, getting things done, and generally how to build great software with no fuss. These things are not taught at school. And very rarely in big companies.

We expect all our interns to be able to be a team leader at the end of their internship.

About us

Most work in the CET timezone in Copenhagen but all work remote across Europe, our CTO is Denmark based but our lead FE is working from Nairobi. We don’t care where you work from – as long as you can keep up!

We build to scale globally from the start so our corporate language is English and "getting stuff done!"

Do you think you can do it? Apply, and let's see what we can do for you.
