Our expectations of you

Qualifications

  • You have already explored LLMs or are interested in building the know-how.
  • Interested in taking responsibility and truly understanding the customer's requirements instead of just processing tickets.

Experience

  • Extensive experience in custom Java development - you have developed real projects for real clients.
  • Several years (>5 years) of experience with Java, JEE/Jakarta EE, Spring, REST APIs, PrimeFaces knowledge is a plus but not a must.

  • Further education and time for your own ideas. We learn with every project and provide the necessary space and resources to acquire new knowledge.
  • Responsibility from day one. We hire senior developers because we trust their experience and want to share our knowledge.
  • Manufacturing atmosphere - Small units, short distances, no departmental boundaries. What you build, you see in action. What you improve, makes an immediate difference.
  • Secure job position. We are hiring because we are growing.
  • Meaningful technology - We don't buy what is just trendy. We implement what endures. Open source, well thought out, sustainable.
  • Modern hardware & quiet working environment - Small office units that enable focused work, equipped with top-notch amenities.
