Junior database administrator (Clickhouse) vacancy at deeplay

We solve the problems of the gaming industry using artificial intelligence, machine learning and big data. We develop applications and services to provide game quality control, decision-making assistance and behavioral analytics. We are one of the best in game analytics.

We have a tender love for mathematics and game theory, and we are also confident in the future of this direction: the geography of the market is expanding, the potential of the gaming industry is growing and developing.

Responsibilities

Of course, we want to find a unicorn who worked with Clickhouse, but we don't really believe in the likelihood of success. Therefore, we will be glad to have a candidate who administered anything actively used Hadoop or just MongoDB.
More details about the setup: the main database is in a click, there is not much data (hundreds of gigabytes). There are a bunch of customized ETLs inward, there are a bunch of customized dashboards outward, mostly on Tableau.

Requirements

Add data correctly. What are the tricks with group operations, how best to use column specifics, what to do if you want to mutate types.
Make load balancing.
Anticipate, prevent and prevent a rake that we have not yet groped.
And you will also take on the pain of transferring routine tasks for servicing the base to the support.
