What this role is all about
As a Senior Full-Stack Engineer in Infobip’s AgentOS Base, you will play a key role in building and evolving large-scale customer engagement and automation platforms, including our AgentOS solution. This role is strongly backend-oriented and requires deep hands-on Java expertise, as the core systems are built around Java and the JVM ecosystem. You will work on technically demanding challenges involving scalability, concurrency, orchestration, and distributed communication flows used across global communication channels. You will join small, initiative-driven teams of 5–6 engineers within a larger engineering organization, contributing primarily on the backend while occasionally supporting frontend development when needed.
