 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.

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.

Improve discovery across documentation surfaces, including search experiences that span multiple apps and sources
Work with and integrate backend services that support the Docs ecosystem (authentication/authorization, platform resources, localization pipeline, survey/feedback service)
Use AI tooling in your everyday work to accelerate delivery (e.g., code generation, refactoring support, debugging, and documentation) while maintaining code quality and security standards
Collaborate with Tech Writers (who create and maintain documentation content) to ensure the platform supports efficient publishing and a consistent user experience
What makes you a strong fit
5+ years of professional experience in frontend engineering (mid-level profiles may be considered depending on overall match)
Strong hands-on experience with React and TypeScript in production environments
