About the company

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

Being part of Infobip Engineering means working on an in-house product used worldwide. As a

Software Engineer you will help deliver scalable, highly available messaging services that

companies use to reach customers on OTT channels such as WhatsApp, Viber, Apple Messages

for Business, Zalo, Kakao, LINE, Messenger, Instagram, TikTok, and others.

You will join OTT Channels engineering in Katowice. We connect enterprises to these platforms:

onboarding, sending and receiving messages, templates, payments, and billing — and we keep

that working when partners change APIs, pricing, or rules on short notice.

This is a mid-level role. You already deliver complex work without being walked through every

step, you care about production, and you can propose a design — not only implement a ticket.

You will start in one product area (for example traffic, onboarding, templates, or billing) and grow

into neighbouring ones. You will not be expected to know every channel on day one.

What you’ll do

-You will own features end to end: design, implementation, tests, rollout, and production follow-up

— not only “the coding part”

-You will build and maintain Java / Spring Boot backend services for OTT messaging

-You will work with partner APIs and webhooks, including version upgrades and programmes with

tight deadlines

-You will take part in production support: investigate incidents, separate supplier issues from our

bugs, and ship fixes

-You will improve reliability, observability, and quality of the systems you touch

-You will review code, write tests, and keep a high definition of done. You mentor more junior

colleagues as you grow into the role

-You will use AI as part of the daily workflow (code, tests, docs, investigation)

-You will work closely with Product and other engineering teams across Infobip

What makes you a strong fit

-You are a Mid Engineer looking for a high-growth challenge, with 3+ years building backend

services (or equivalent depth — we care about independence more than years)

-You have strong Java (or Kotlin) and Spring Boot; you are comfortable with Maven, Git, and

automated tests

-You have shipped and operated something in production: logs, metrics, incidents, not only

green unit tests

-You can take a vaguely specified problem, break it down, propose a design, and deliver it

with stable quality

-You write code others can review: clear, tested, no cleverness for its own sake

-You communicate in English with engineers and product; you ask for feedback and give it

-Curiosity about integrating with third-party platforms beats prior experience with a specific

channel

Nice-to-have qualifications

-Kafka, REST APIs, OpenAPI

-Relational and/or document databases; Redis, CI/CD, Docker, high-availability systems

-Messaging, CPaaS, or payments experience

-Polish is useful in the Katowice office, not required

Why you’ll love it here?

-Feature team in Katowice, close collaboration with Product

-Agile delivery; Jira, Git, Confluence, Slack

-Production support rotation — you will learn live systems, not sit on the sidelines

share the same passion and talent that helps us achieve our mission. That’s why Infobip is

committed to creating a diverse workplace and is proud to be an equal-opportunity employer.

-All qualified applicants will receive consideration for employment without regard to race, color,

ancestry, religion, age, sex, sexual orientation, gender, gender identity, national origin, citizenship,

disability, veteran status, or any other part of one’s identity.
