Rohde & Schwarz Topex Tech Stack

VoIP and voice switching systems for mission-critical communications

Telecommunications Bucharest, 1 201–500 employees Founded 1990 Privately Held

Rohde & Schwarz Topex builds VoIP and switching infrastructure for air traffic control, maritime, and enterprise environments. The stack—Linux, C, SIP, Cisco, PostgreSQL, plus security tools (Nessus, Qualys, OWASP ZAP, Burp Suite)—reflects a mature, heavily regulated product. Current project work on a VoIP-based ATC voice system and AI-driven quality tooling, combined with pain points around legacy signaling maintenance and release bottlenecks, suggests the company is simultaneously shipping production-critical systems while modernizing underlying architecture.
