About The Position

The Sr DAS Support Engineer provides Level 3 technical support and service reliability for multi-OEM distributed antenna system (DAS), in-building wireless, and private LTE/CBRS environments. The role diagnoses complex RF, fiber, coaxial, hardware, software, and management-connectivity issues; owns incidents through resolution; coordinates recovery with OEMs, carriers, field teams, and customers; and produces root cause analyses and after-action reports. The engineer prepares and executes approved maintenance and change activities, including firmware upgrades, configuration changes, commissioning, integration, and stabilization. This includes defining risk controls, backups, rollback steps, acceptance criteria, and verification; coordinating remote and onsite work; and supporting customer acceptance testing. The position also maintains accurate site and system records, develops troubleshooting procedures and runbooks, mentors engineers, and communicates service impacts and technical findings to customers and internal stakeholders, including hospital clinical and facilities teams. Scheduled after-hours maintenance and participation in an assigned support coverage rotation are part of the role.
