Summer Internship Data Scientist

July – October 2022

Do you want to gain professional data science and machine learning experience in a fast changing world of online advertising? Would you like to learn from leading data scientists and machine learning experts in the industry for a few months? Do you want to deepen your knowledge and gain practical experiences through mentored internship?

We are seeking individuals passionate in areas such as deep learning, computer vision, natural language processing, machine learning, reinforcement learning, mathematical optimization, computational statistics, graph theory, heuristic search and applied mathematics.

What we do

At Zemanta, we’re building the most advanced native advertising platform in the world. With over half a billion machine learning predictions calculated every second we are committed to advancing the field of artificial intelligence and machine learning.

Summer Internship

Our summer interns have an opportunity to make scientific and core algorithmic advances and apply their ideas at a large scale and materialize them directly to production with an immediate effect on the business. We use state-of-the-art tools and cutting-edge machine learning and deep learning algorithms, produce terabytes of data daily and process it with an in-house distributed AutoML framework for effective offline research.

Our interns have a chance to improve their industry-grade data science skills, gain additional knowledge and work experiences and take advantage of our internal knowledge sharing practices (talks and presentations from coworkers, invited talks, reading scientific papers and books, guided discussions or watching conference talks).

This is a paid internship lasting 12 weeks starting in July 2022. We are looking for students that are pursuing a Masters or PhD degree in one of the areas listed above and have some software engineering or data science experience.

The interns (3-4 students) will work with their mentors on specific individual projects and will be part of our teams of data scientists. The majority of the work will be done in the hybrid mode (2-3 days at the office in Ljubljana), depending on the state of the epidemic. The research findings of the internship projects could also have a potential to be upgraded into a research paper or thesis (Zemanta has a rich history of mentoring data science undergraduate and graduate theses).

Responsibilities & Requirements


  • End-to-end ownership of a specific research project and performing individual research (under the mentorship of our experienced data scientists).
  • Analyzing and presenting results and research findings to other coworkers.
  • Learning about the latest technologies and testing them in practice.
  • Working closely with our data scientists and software engineers to expand and enhance our data pipelines and infrastructure.


  • Currently is in the process of obtaining a Masters or PhD degree.
  • Knowledge in fields related to artificial intelligence,  machine learning, data science, computer vision, natural language processing, optimisation, computer science, statistics or applied mathematics.
  • Some experience in solving analytical problems using quantitative approaches and analyzing large scale high-dimensionality data.
  • Practical knowledge of at least one of the following programming languages: Python, Java, Go, C, C# (Knowing TensorFlow and the SciPy stack is a plus).


  • Registration open: 7.3.2022 - 17.5.2022
  • Selection process: 17.5.2022 - 22.5.2022
  • Internship: 4.7.2022 - 30.9.2022


When will this summer internship start/end?

The Zemanta Data Science Summer Internship will start on 4th of July and will conclude around the end of September. If there is a wish from both sides, we could extend it for a couple of weeks into October, subject to later discussion.

Can I start at a later date?

Sadly no. We plan an intensive week of onboardings and scheduled presentations aimed at preparing you for your upcoming projects and getting to know your mentors and coworkers.

Will I be compensated?

Yes! This is a paid internship.

Do I need to have prior work experience?

No! However, having past work experience, especially from fields of data science or software engineering is an advantage.

Can I study something different than Computer Science?

Absolutely! We are looking for bright individuals regardless of their background.

Do I need to have programming experience?

Some basic practical knowledge is required. You will need to implement all of your research ideas, from prototypes to production models. It is advised that you are familiar with Python and Tensorflow.

How will you select the interns?

We want to select the interns which will be able to learn the most in this experience! Our selection will be based on a number of different criterions, including past software engineering and data science experience, motivation and so on.

Can I work remotely?

No. You will need to be able to come to work in our Ljubljana office. However, some of the work will be possible to do remotely.

Can I register for summer school and summer internship at the same time?

Yes! Although our interns will have a reserved spot in our summer school automatically, it is still advised to register for both (if you are interested in the summer school) in case you are not selected for this internship.

Can I take a vacation/break during the internship?

Yes! You can take up to a week or two long break any time during the duration of the internship. However, be aware that this internship is primarily meant for you (acquiring additional knowledge and practical skills) and we expect that you will take on this internship with all seriousness and devote quite a bit of your time.

I do not have a student status, can I still attend the internship?

Yes, as long as you are not employed elsewhere and have a permission to work in Slovenia.

Do I need to know Slovene in order to attend the internship?

No. Our coworkers come from different parts of the world and we all speak English.
