Company created by engineers
for engineers

  • We have created a company where experienced engineers implement projects that they have knowingly chosen. We bring the partners closer to their business goals and we continually improve the expertise of j‑specialists. We invest in people, because they are at the heart of j‑labs.

Reliability, merit approach and technology

We create an environment where work gives us satisfaction and personal growth. The organisational culture relies on values and collaboration is initiated with people who share our beliefs. Thanks to this, we face challenges together.

Who we are?

We are reliable

We devote ourselves to what we do and we maintain high quality.

We go with merit approach

We build a team of experts in specific fields, who continue to develop.

We focus on technology

In the Java “laboratory” (hence the name j‑labs!), equipment and results go hand in hand with technology development.

  • I had the pleasure of working on j‑labs obtaining ISO 9001 and 27001 certifications, which confirm the high quality of our services and the safety of our processes! With a base of procedures that have been in place at j‑labs for a long time, adapting them to ISO requirements was just a formality.

  • The technical credentials of our engineers, as well as the choice of projects with respect to technological issues, are our priorities. Whether you programme in .net, Java or prefer front-end is important for us. Wherever possible, we propose solutions relying on verified as well as modern libraries and frameworks. This allows j‑labs, j‑people and me to continually develop in the dynamic IT world!

  • I've been working at j‑labs for almost five years , and I have the opportunity to observe the company's development. Despite the truly dynamic growth, the company manages to avoid a dry, corporate atmosphere and bureaucracy, which is a significant advantage. The ability to switch projects within the company is another major plus.

  • A significant advantage at j‑labs is the space for implementing new solutions. The situation in technology is constantly changing, so the opportunity to introduce innovations gives me considerable satisfaction. At j‑labs, I have the space, resources, and time to both develop my abilities and test them within a live organism, which is a large, functioning project.

  • From the very beginning at j‑labs, we've been guided by the principle: "treat others as you'd like to be treated" – this applies to relationships with employees, candidates, and business partners. Honesty, transparency, keeping promises, and talking about things as they are without any pretense are particularly important to us. I highly value that in our teams, we cultivate these qualities, and integrity is at the top of the j‑labs vocabulary.
