What you’ll do

  • You will become part of our team, which develops software for retail chains around the world.
  • But it's not just about writing code – you will design solutions, analyze requirements, optimize performance, tests, and write technical documentation. In short, you will be involved from the initial design to the final deployment.
  • We build the backend in Java (primarily Spring) and the frontend most often in JavaScript or TypeScript.
  • We work in smaller, independent teams, often connected to colleagues from abroad – so you can expect to communicate in English daily.

 

What you bring

  • We would be happy if you have a university degree in a technical field, but if not, you can compensate for this with relevant experience.
  • Our software is complex, so we are looking for someone who already has experience in development – ideally at least 5 years.
  • A developer who is proficient in Java backend (preferably Spring) and can also handle frontend in JavaScript or TypeScript will in with us.
  • Knowledge of SQL will be useful, also with tools such as Maven, Git, JUnit, or IntelliJ.
  • Familiarity with REST APIs, OpenAPI/Swagger, YAML, and CI/CD tools such as Jenkins or Nexus would be a plus.
  • We are looking for someone who is not afraid of responsibility, likes to come up with their own ideas, and wants to be part of a team where work makes sense
