Join Sportradar's Blue Team, a backend engineering group building core betting platform infrastructure. You'll work with Java, Spring Boot, Kafka, and event-driven architecture to develop high-performance, scalable systems processing millions of transactions for betting clients worldwide.
In this role, you will implement domain logic and system definitions, collaborating with product teams to provide technical feedback and shape requirements. You'll build reliable, maintainable solutions that minimize bugs and reduce operational overhead. The team values continuous learning—whether deepening domain expertise, mastering current technologies, or exploring new tools and approaches. You're expected to actively suggest improvements during planning sessions, retrospectives, and code reviews.
Sportradar is the world's leading sports technology company, serving over 1,700 sports federations, media outlets, betting operators, and consumer platforms across 120 countries. The company operates with engineering offices in Europe, Asia, and the US, fostering a collaborative, globally distributed environment with social events and team-building activities.
The role emphasizes autonomy and structure in equal measure. You'll work in an office-first model (five days per week on-site in Mostar, though certain exemptions may apply by location). The company offers flexible working hours, global Employee Assistance Program, well-being apps (Calm, Reulay), online training, and an inclusive community.
