Citema Systems is a Munich-based consulting and development firm focused on blockchain, cybersecurity, big data, and AI implementations. The tech stack reveals a hybrid engineering culture: legacy mainframe experience (COBOL, PL/I, DB2, ISPF) coexists with modern web and IoT tooling (JavaScript, Python, Qt, RabbitMQ), and active hiring tilts heavily toward mid-level engineers (24 of 30 engineering roles), suggesting either project staffing across multiple engagement types or internal product scaling alongside services.
