In LEOCODE we work with international clients. We are proud of about 100 successfully completed projects and try our best to reach the most demanding customers from the technical point of view.

We are a software development company that has been operating on the international market for ten years. As part of our activities, we advise clients on how they can solve business problems using new technologies. We are interested in JavaScript, React.js and Node.js and more.

We are always on the hunt for talent and, above all, engagement, teamwork and initiative.
In return, we provide a highly supportive yet challenging environment in witch you can develop your natural skills and sharpen your instincts with our expert guidance.

We value friendliness and team spirit. You can simply be yourself, no dress-code or unnecessary guidelines - as long as you are a true team player.

We're ambitious and strive to be the best, so our culture is largely based around self-development and knowledge sharing. We want to grow, go to meetups and conferences, and we invest in your skills.

Do you prefer to work in early hours of the morning, or do you feel most productive under the cover of the night sky? Doesn't matter to us - work when you please.

We organize team get-togethers once a year to discuss our progress, get to know each other better, and party the same way that we work - hard!

We believe that remote work is the way of the future. Don't worry about stressing to get to the office on time - work from home, from a coffee shop, or from a sunbed by a pool. 

We are a software house, just better!
