Winter Internship 2027

Make a first step towards your career in AI engineering. Gain practical experience and learn from experienced mentors. Being a part of Infobip Engineering department means working on an in-house developed product and delivering solutions on a global level. If you are a student of higher or final year of studies in the field of IT, join our AI engineering internship program that starts in February 2027 and get a chance to land your first job at Infobip!

What this role is all about:

As an AI Engineering Intern, you will join our Internship program and work on real, data‑driven problems that directly impact our products and users. You will gain hands‑on experience across the full AI engineering lifecycle, from data processing and model experimentation to building production‑ready AI services. You’ll collaborate with experienced engineers and product teams, learning how modern AI systems are built, evaluated, and scaled in a business environment.

What you’ll do:

  • Build and experiment with AI/ML solutions using Python, Jupyter, and libraries such as PyTorch, TensorFlow, scikit-learn, and Hugging Face Transformers to name a few.
  • Develop production‑ready services in Python, building scalable and maintainable APIs with FastAPI.
  • Work with large datasets and learn the end‑to‑end flow of data collection, manipulation, and usage.
  • Design and build agentic workflows using LLMs, tools, and APIs (agents, tool use, orchestration frameworks, etc.)
  • Integrate with leading AI providers (e.g. OpenAI, Anthropic, Google, open-source models) for text, image, and multimodal use cases.
  • Apply best practices in context engineering, evaluation, and model iteration.
  • Write clean, testable, and maintainable code with a focus on reliability and scalability.
  • Use tools such as Git, Conda, Docker, Kubernetes, and Jenkins to put your code into action.
  • Work in agile teams and learn agile development methodologies.

What makes you a strong fit:

  • Final‑year student in a relevant field (e.g. Software Engineering, Computer Science, Mathematics, Data Science, etc.)
  • Strong interest in both AI as a technology from a theoretical viewpoint and its real-world applications.
  • Comfortable working with Python and eager to learn modern AI/ML and data engineering tools.
  • Fluent in English, at a conversational level.
  • Available to start with internship on February 8th, 2027
  • You hold valid student rights from „Studentski Centar“ throughout the entire internship period (6 months).
  • You can work a minimum of 30 hours per week.

Nice‑to‑have qualifications:

  • Experience with advanced context engineering practices, RAG, and AI agents in general.
  • Familiarity with vector databases.
  • Exposure to cloud platforms.
  • GitHub profile with projects to showcase.
  • Participation in student projects, Kaggle competitions, hackathons, workshops, or similar activities.
  • Previous internship experience.
  • Availability to continue working full‑time after completing the internship.

What you’ll gain:

  • Hands-on experience with state-of-the-art AI systems in production.
  • Mentorship from experienced engineers and AI practitioners.
  • Exposure to modern AI architecture (LLMs, agents, data pipelines, evaluation).
  • Insight into how AI drives real business value.
  • Opportunity to grow into a full-time role.

Internship timeline:

  • Application deadline (mid of December)
  • Imocha online testing (By the end of December)
  • Interviews and selection process feedback (January)
  • Start of internship program (February 8th)
  • Orientation week in Zagreb Infobip campus (February 8th - 19th)
  • Working with the mentor and within a team (February - August)
  • End of the Internship program (August)

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
