Working at Infobip means being part of something truly global. With 75+ offices across six continents, we’re not just building technology — we’re shaping how more than 80% of the world connects and communicates.

As employees, we take pride in contributing to the world’s largest and only full-stack cloud communication platform. But it’s not just what we do, it’s how we do it: with curiosity, passion, and a whole lot of collaboration.

We operate with an AI-first mindset, embedding intelligent tools into our daily workflows to work smarter and more efficiently. Every role here benefits from and contributes to this approach.

If you're looking for meaningful work and challenges that grow you in a culture where people show up with purpose, this is your opportunity.

Let’s build what’s next, together.

As a Software Engineer in the IBOS Base team, you will work on internal products and integrations that support Infobip’s Revenue organization and business operations. The team develops applications and AI-enabled solutions that help automate workflows, improve sales processes, and reduce manual operational work across the company.

You will contribute to products focused on data consolidation, workflow automation, and AI-assisted insights for Revenue teams. The work includes building integrations between multiple internal and external systems, developing backend services, and contributing to frontend and AI-related initiatives where needed. The team works in a fast-moving environment with a strong focus on practical problem solving, ownership, and continuous product development.

This role is suited for engineers who already have solid software engineering fundamentals and want to continue growing in distributed systems, integrations, and AI-supported product development.
