Position Overview The Client is seeking a Contact Center Systems Engineer to provide operational engineering support for an enterprise contact center platform supporting internal helpdesk and employee support organizations worldwide. The successful candidate will support the existing commercial contact center platform while also contributing to the implementation and migration of a successor platform built on open-source telephony technologies. This role is part of a small, distributed engineering team and requires close collaboration with engineers and operational stakeholders across multiple regions. The engineer will provide production support during an assigned Pacific Time shift, troubleshoot incidents across voice, network, and application layers, and participate in the design, configuration, testing, and migration of contact center capabilities. The position supports global operations during the assigned shift and requires structured handoffs with engineering teams in other regions. There is no separate after-hours pager obligation; issues outside the engineer's scope will be escalated to the appropriate Client engineering resources. Key Responsibilities Contact Center Platform Operations Configure, maintain, and troubleshoot enterprise contact center platforms. Develop and maintain routing strategies, queues, IVR flows, agent targeting, and interaction workflows across: Voice Chat Task Email Troubleshoot production issues involving contact center applications, voice services, network connectivity, and supporting infrastructure. Investigate and resolve call-flow, routing, and media-path issues. Support number provisioning, number porting, and regional telephony routing. Monitor system health and proactively identify potential service-impacting issues. Resolve assigned incidents, defects, and operational requests within defined service levels.
