Job description

We are looking for a Full-Stack Developer (Java, Spring Boot & React) for a long-term and full-time position in a growing cloud-native SaaS product. Apply for this role if you want to work on a stable, evolving system while contributing to modern backend and frontend development.


What you can expect:

  • Long-term product development within an international team and established customer base

  • 100% remote, flexible working hours

  • A mature SaaS ecosystem including Web (React), API, and mobile components

  • Ownership of full-lifecycle feature development from concept to deployment

  • Active participation in planning, architecture discussions, and daily team collaboration

  • Room for growth – from structured onboarding for junior developers to architectural responsibility for senior profiles

  • Direct technical exchange with the team – no long HR processes


What you’ll do:

  • Develop and maintain backend services using Java and Spring Boot

  • Build and enhance frontend components using React

  • Work on a high-traffic SaaS platform with focus on scalability and maintainability

  • Refactor and improve existing components in a mature production system

  • Use modern development tools (including AI coding assistants) to improve efficiency and code quality

  • Collaborate closely with team members on architecture, code reviews, and technical decisions


What we expect from you:

  • A bachelor's or higher degree in Computer Science, Software Engineering, or a related field

  • Strong understanding of software engineering principles, testing, data structures and algorithms

  • At least 1–3 years (Junior) or 3+ years (Mid/Senior) of professional experience with Java and Spring Boot

  • Practical experience with React (or comparable frontend framework such as Angular)

  • Your main strength can be either backend (Java/Spring Boot) or frontend (React). What matters most is solid software engineering fundamentals and the willingness to work across the stack where needed.

  • Ability to work independently and take ownership of tasks

  • Good communication skills and proficiency in English

  • Interest in modern development workflows, including AI-assisted development tools


We are happy to explain all further details and answer any questions in a personal call.
