Frequentis Tech Stack

Safety-critical command-and-control systems for air traffic, emergency services, and transport

IT Services and IT Consulting Vienna 1,001–5,000 employees Privately Held

Frequentis operates in the highest-stakes corner of enterprise software—air traffic control, emergency dispatch, and transport infrastructure where downtime isn't an option. The company is scaling engineering-heavy (124 engineers across 208 open roles) while adopting Ansible and Python, and actively migrating legacy databases to modern tooling (Jira, microservices frameworks). The project list signals a shift toward containerized deployments and CI/CD maturity, alongside persistent compliance headwinds (ISO 45001, industry standards) that typically consume engineering cycles in safety-critical vendors.
