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.

What this role is all about
As a Senior Software Engineer in Infobip, you will work on Infobip’s documentation products that developers and partners use to understand and integrate with our platform. The team owns Docs (the main documentation platform), API Docs UI (for browsing and exploring API documentation), and partner documentation platforms, including localization coverage. You will build customer-facing experiences in React, TypeScript, and Next.js, and collaborate on platform capabilities behind the scenes, such as authentication/authorization for Docs and services that power discovery across Docs and API Docs. A key focus for this role is helping scale the solution so we can onboard 10–15 new partners who may require customized documentation while staying in sync with core changes.
