This position is posted by Jobgether on behalf of a partner company. We are currently looking for a Senior Backend Engineer (Kotlin/Java) in Slovenia.
This role offers the opportunity to design and build highly scalable backend systems used in complex, distributed environments. As a Senior Backend Engineer, you will work on high-throughput, event-driven architectures and contribute to mission-critical services that integrate with third-party platforms at scale. You will collaborate with experienced engineers in an Agile and DevOps-driven environment, where code quality, reliability, and observability are top priorities. The position is fully remote and provides exposure to challenging international projects. Your work will directly impact system performance, resilience, and long-term technical scalability. This role is ideal for engineers who enjoy solving complex backend problems and taking ownership of production-grade systems.
Accountabilities
We use an AI-powered matching process to ensure your application is reviewed quickly, objectively, and fairly against the role's core requirements. Our system identifies the top-fitting candidates, and this shortlist is then shared directly with the hiring company. The final decision and next steps (interviews, assessments) are managed by their internal team.
We appreciate your interest and wish you the best!
