About Neontri:

Neontri is a leading provider of custom software solutions and total talent management. With a strong focus on fintech, banking, and e-commerce, we pride ourselves on building long-lasting client relationships, as evidenced by our 100% client retention rate in 2022. We have successfully delivered over 400 projects across four continents and have been recognized with multiple awards for our innovative solutions.

What might set us apart from other companies and why should you consider collaborating with us?

  1. We are people who value honesty, openness, and a VERY GOOD work atmosphere.
  2. We listen to your needs. It's essential for us that you feel comfortable with us. If the time comes when you wish to change projects - no problem.
  3. Want to work 100% remotely but still meet at the company's headquarters occasionally? That's not an issue.
  4. Most of our team works entirely remotely; however, we periodically meet during integration meetings or come to the office for a change of work environment.


We're embarking on a project with a large e-commerce company where we'll be developing a middleware layer between the mobile application and the backend. The project is being built from scratch. Tech Stack: Java, Kotlin, Spring Boot, GCP, Kubernetes, JVM.

Knowledge of Kotlin is essential.

If you're interested in having a significant degree of flexibility in how you work, influencing your work environment, and being part of smaller, knowledge-sharing teams - you've come to the right place :)

We don't have fruit Thursdays or a barista, but we can offer:

  • Collaboration based on a B2B contract or a Contract of Mandate,
  • An exciting and developmental project - without maintenance :)
  • Fully company-funded medical care (with a choice from 3 packages),
  • Opportunity to join the MultiSport card,
  • A training budget,
  • 100% remote work,
  • We don't do overtime! Balance is key,
  • A short, usually one-stage recruitment process. Your recruitment adventure will start with a 20-minute phone call with our HR department (Ola here - nice to meet you).
