About Software Mind

Software Mind is a Polish software services company staffing project teams from Kraków and Warsaw. Almost every open European role is engineering: Python and OpenStack, data platform work, Databricks and cloud AI, and Kubernetes SRE. As with any consultancy the work is on a client's system rather than a product of its own, and the bracketed code on each title is the account.
