About this career

DBAs design schemas, tune queries, plan backups, and stand between an organization and a very bad day. Strong knowledge of SQL, indexing, and one or more database engines (Postgres, MySQL, Mongo) is essential. The role is operational by nature — comfortable on-call rotation is part of the deal.
