Data Engineer

At Slovak Telekom, we are constantly moving forward with the maximum priority of digital products for our clients (mobile applications, online shopping, internal and external tooling for our customers). We create solutions on the level of individual countries (Czech Republic / Slovakia) or even on the level of transnational solutions using modern delivery, automation, DevOps and the creation of new solutions using the microservices architecture.

For our Data and Analytics department, we are looking for Data Engineers, who will help us to modernize our data stacks and enable teams’ visibility on their customers happiness. Are you someone that likes to work closely with software engineers and teams to help them push data to a more modern stack (or even contribute directly to their products)? Send us your CV or a story or two about how you crashed a dwh or how you were able to write an ELT job that pushed data to object storage…. 

If you want to participate in solutions for millions of clients, at the same time use the latest technologies and do things differently than is common in the corporate world, send us your CV.
