You will work with modern tools

This is how you would progress at Mirumee

We are focused on your progress - If you still lack experience or expertise in some field, our goal is to help you become an outstanding senior developer. If you are already confident about your skills, we will put you in the driving seat and give you the enviroment to further progress your leadship skills and other competencies.

If you’re a JUNIOR...

We offer mentorship and growth. We will give you time, and resources, to gain great experience working side by side with more experienced developers.

Then you will have plenty of opportunities to sit in the driver’s seat. You will be responsible for architectural decisions, planning and most likely will be in charge of a small team, that is if you want to be a leader.
Our effort will focus on helping you grow your leadership skills and aquire new experience with the latest trends and tools.


I remember the feeling when my code was merged to our commercial client’s existing system for the first time. It was a milestone in my career. I felt a great responsibility and satisfaction that people in the real world were using software that I helped to build.

I think that you should always do things you love and constantly strive for a better self. I've been working at Mirumee for several years but I still feel that I am evolving and broadening my horizons. Working in a friendly atmosphere with people I can always count on reinforces my belief that I am exactly where I should be.
