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 have been working as a front-end developer for over a decade, and I have dozens of completed projects in my portfolio. At j‑labs, I support other programmers as a Front-end Guild Master and here I had the pleasure of fulfilling my professional dream - to appear at conferences such as Devoxx Poland or 4Developers. I am driven by sharing knowledge, and at j‑labs I have space for this. j‑labs gives me a real chance to level up my career. Here we really do good IT or nothing at all.

  • Since I have been working at j‑labs, I experience every day how important it is to have space for professional and personal development. It is not only a place where I can use my skills and passions to implement ambitious projects, but also where I build relationships with people who share my interests and values. j‑labs is a community of experts - full of passion, support and motivation. The variety of projects and the opportunity to work in teams in which each member brings something unique makes me constantly learn and develop. Thanks to this, I feel that my work has a real impact not only on my personal achievements, but also on the success of the entire organization.

  • j-labs is the human side of IT, really good IT. Thanks to j‑labs and the client, I was able to learn Blockchain from scratch, and today, after 4 years, I am giving lectures, sharing the acquired knowledge and experience. My work is appreciated and respected, which gives me a sense of professional fulfillment, and integration and sports challenges create a great atmosphere. Become one of us - j-People are, above all, people, not just lines of code!

  • What continually delights me in j‑labs are the positive atmosphere and openness, which influence our reliable and merit cooperation. We like to argue, to look for improvements and more convenient and more efficient solutions together. In all aspects of our j‑labs life, we are greatly attached to quality – we hire highly-competent specialists and we focus on valuable projects.

  • 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 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.

  • I've been working at j‑labs for almost six 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.

  • For me, j‑labs is, above all, committed people with whom I can implement bold projects, both business and personal. In addition to working for one of the largest technology companies in the world, I take part and engage in organizing events promoting new technologies, programming and the development of digital competences. Conferences, workshops, meetings with interesting speakers - all this allows me to develop comprehensively (not only technically!) and share my experience with others. And at the same time meet a lot of cool people!

  • Thanks to j‑labs, I had the opportunity not only to work every day on an exciting project for one of the largest banks in the world, but also to use my passion for creating graphics and games to promote our company. The employee's potential is used to the maximum, which makes work interesting and effectively prevents burnout. We cannot ignore the atmosphere of mutual kindness between j‑People and the opportunities provided by j‑labs for development in many areas.

  • I still remember the first call from the j‑labs recruitment department. The series of uninteresting employment processes for other companies was interrupted with a huge dose of professionalism. In addition to continuous development for the client, both professional and financial, on behalf of j‑labs I met dozens of people during technical evaluations, created games, conducted training, made public appearances, and currently am leading a project to revolutionize the recruitment process.

  • 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.

  • I have been with j‑labs since 2018 and in the course of these years have worked hard together with the team to earn the client’s respect and trust. We propose architecture, technologies and solutions and are accountable for them and this is great!
