About The Position

Motorola Solutions is seeking a Principal Systems Engineer to lead the design and implementation of ASTRO 25 and related communications solutions for Department of Defense and other federal government customers. The engineer will work with a multidisciplinary field team—including project managers, systems engineers, system technologists, construction managers, and customer service managers—to lead technical aspects of projects from design through final system acceptance. The role includes customer and consultant engagement, system configuration and testing, field implementation, troubleshooting, documentation, and upgrades. The position is remote and requires the candidate to reside in the DC Metro area. It requires 25–50% travel to customer sites around the country. The engineer will work primarily from a home office, often without local supervision, and may need to manage multiple concurrent projects and changing priorities.
