Are you cut out for the job?

As this is applied research position, we are looking for people with university education - Master's or higher degree either in machine learning related field or in cybersecurity. People with Data Scientist, Computer Science, Data Mining or Statistics background are welcome, ideally with previous work experience in the field. This position is also suitable for experienced software engineers that have at least some experience with machine learning or data science.

We are looking for people with advanced programming skills especially in Python, as we strive for quality code that can be understood easily, and not quick fix-and-forget schemes. Of course, for ML prototypes, it’s expected to produce not-so-nice code, but once a prototype turns out to be successful, a proper rewrite with peer code review should take place.

A big advantage is to have experience with ML frameworks and data science (eg. tensorflow, torch, scikit, pandas, etc.) and big data technologies (hadoop, spark, impala, kafka). Bonus points for a basic understanding of computer security, network security or even reverse engineering.

The appetite for drinks, beers, food and a great time will be saturated on several on- and off-site teambuilding activities, annual Christmas party and a big company party with a cover name 'Zranica'.


Brief description of the company

The beginnings of ESET date back to 1987, when two young programming enthusiasts, Peter Paško and Miroslav Trnka, wrote a program for the detection of one of the world’s first computer viruses. They did not know that they had created one of the most successful antivirus programs in the world – dubbing it NOD. In 1992, together with their mutual friend Rudolf Hrubý, they formally established ESET.

What started as the brainchild of a few friends has evolved into the most valuable international brand of any Slovak company. Today ESET’s NOD32 technology protects over 100 million users across the world.

This success did not come overnight. The company’s global success and growth was given a boost in 1998 with its first “VB100” award from the prestigious Virus Bulletin magazine. Since then, we’ve received this accolade more than 100 times.

Today, over 1,800 employees around the world drive the company’s success – a telling increase from 3 in 1987 and 135 in 2006. Almost 900 of them are based in Slovakia, the home of ESET headquarters.

Throughout the company’s expansion, we have stayed true to the principles on which we were founded, and we remain independent in order to continue to meet new challenges.
