About Ragnarson

We are the Tech team behind the success of top European Startups, and we are looking for future tech leaders.

What makes Ragnarson’s attitude different from the rest of the market is that we want our developers to be future tech leaders. It means that besides technical expertise we emphasize their development in other aspects such as business knowledge, communication skills, or management.

If you see yourself in the next 5 years as someone who influences tech and team choices, Ragnarson is the place where you can acquire relevant skills. You can become a tech lead, startup owner, CTO, or an especially valuable team member.

We believe in and train the so-called T-shaped developers. This means that you have a deep specialization and broad general knowledge. We know that if you connect technical expertise with business skills, the outcome of your work will be astonishing.

The Position

So, you’re considering a job at Ragnarson? It's in our best interest to help you find out whether Ragnarson is the right place for you. Deciding how we will be spending 6 to 10 hours of our lives together, five times a week, is paramount. It shouldn't be down to a simple benefit versus requirements comparison.

There is no point in running yet another software development company without a good reason. For us, it's how we treat others as we would like to be treated (read our manifesto). That's why at Ragnarson we have created an environment where people achieve their fullest potential and are able to express themselves through their work. If you don’t see yourself in our story, Ragnarson is probably not the place you are looking for.

In order to foster this environment, the company has transparency at its core. All staff have access to our complete financial records, expenses, income, client/employees rates etc. All of the processes, decisions and documents around them are open too. As uncle Ben said, “With great power comes great responsibility.” So you will need all these details to make various decisions at the company - whether or not to recruit somebody, accept or reject a client's project, give feedback to others, allocate the profit or save it for the future. Making such calls will help you develop and broaden your perspective.

Obviously, you will be working with our clients on their products too. But that’s definitely not all there is to working at Ragnarson.

You won’t find empty phrases like “flexible time”, “interesting projects”, “international clients” or “work in a young and dynamic team” commonly used in most job offers. Those terms have become devalued in IT jobs and mean exactly nothing. At Ragnarson you will be able to choose and adjust your perks to boost your productivity.

Given you're still reading this and you haven’t seen the salary yet (because there is none in this narrative), your motivations are not strictly financial. That's great because for us money is a commodity that frankly, is easy to acquire nowadays. It’s much harder for you to find a work environment that you believe in and for us to find an engaged teammate.

Twice a year at Ragnarson you will set your salary to whatever you think is right, based on the company's budget, feedback from the people you have worked with and the market comparison. Nobody will have a right to interfere with that decision.
