Kakao Details DB and Hadoop Engineering Internship Roles

Kakao's Talent Acquisition Team summarized the content of the 2022 Winter Tech Internship briefing to introduce the characteristics of the DB Engineering Part and the Hadoop Engineering Part. The DB Engineering Part manages user-facing data for Kakao services, primarily using MySQL, PostgreSQL, and MongoDB. They develop a DBaaS (Database as a Service) platform to automate instance creation, modeling consulting, performance tuning, monitoring, and incident response. The Hadoop Engineering Part is responsible for a big data platform processing approximately 400 PB of data, operating over 140 clusters and more than 9,000 data nodes. Through KHP (Kakao Hadoop Platform), they perform Hadoop distribution packaging, cluster construction, and resource monitoring, serving an SRE (Site Reliability Engineering) role to provide a stable data analysis environment. Major or experience are not mandatory requirements for hiring; for DB engineering, candidates must pass a coding test and are evaluated on their problem-solving approach through a pre-assignment, while for Hadoop engineering, the focus is on the ability to quickly adapt to new environments and generate ideas.
