Requisition ID 35718 Office Country Bulgaria Office City Sofia Division Information Technology Full-Time/Part-Time​ Full Time Contract Type Fixed Term Contract Length 3 years Posting End Date 06/08/2025

Step into a high-impact role where Java mastery meets real-world complexity. You'll be building enterprise-grade, cloud-native applications using Java 17+, Spring Boot, and microservices architecture. Driving clean code, smart design, and performance at scale. From RESTful APIs to custom integrations and scalable data solutions, you’ll own the full development lifecycle and operate with real autonomy. If writing elegant, maintainable code and solving complex software problems are your strengths, this role will feel like home.

But it’s more than just code. You’ll lead on quality, through robust testing, TDD/BDD, and CI/CD automation, while also ensuring your solutions perform in production with security, observability, and resilience in mind. You’ll collaborate across architecture, DevOps, and cloud teams (Azure, Kubernetes, Docker) to deliver scalable systems that make a real difference. If you’re ready to take the reins and shape the future of enterprise Java applications, this is your moment.
