Jobs in Prague, Czechia

About the role

As part of the CallMiner Engineering and Operations Team, the DevOps System Administrator is responsible for the reliability, security, and performance of the infrastructure that delivers CallMiner's intelligent CX automation solutions to enterprise customers, including OmniAgent. The primary focus of this role is managing and supporting customer-facing infrastructure: deploying, operating, and troubleshooting the systems that connect AI virtual agents to customers' contact center and telephony environments. A central part of this responsibility is SIP telephony integration – owning the end-to-end technical path from the moment a customer's phone rings to the moment the AI agent answers, across SIP trunks, carriers, PBX systems, session border controllers, and enterprise networks. The DevOps System Administrator partners closely with Engineering, Delivery, and Customer Success teams to support customer deployments, resolve infrastructure and connectivity issues, plan capacity, and ensure the availability of real-time, voice-first services handling millions of customer interactions annually. The ideal candidate is a proactive problem-solver who thrives on ownership and operational excellence in a fast-paced environment. This position is based in Prague, Czech Republic, and supports CallMiner's Intelligent CX Automation platform serving customers throughout Europe and globally.
