About the position

We are looking for a Unified Communications (UC) Engineer to help grow, monitor and manage our global voice and video infrastructure. This role sits within our larger IT group and will require you to deliver smart solutions in a fast-paced environment without disrupting the daily workflow.

Our UC Engineers are experts at multitasking, monitoring alarms generated by our voice and video systems, juggling project-related tasks and serving as an escalation point for users and other technology groups. You’ll interface daily with various tech teams across the firm—including IT Operations, Cybersecurity and Networking—to provide capacity planning, develop standards and best practices and improve documentation across our global UC infrastructure.

The right candidate will be passionate about solving complex problems and supporting users with robust and flexible technical solutions.
