System Architect, DAS / Wireless

AFL Telecommunications•Dallas, TX

11d

About The Position

The System Architect designs, models, optimizes, and supports deployment of advanced Distributed Antenna System (DAS) and in-building wireless solutions for large venues and enterprise environments. The role performs moderately complex to advanced RF engineering activities supporting design, development, commissioning, and optimization of carrier-grade wireless networks using iBwave and other RF planning and design tools. The System Architect provides technical leadership and owns the overall system architecture for assigned projects, including active DAS, Air Radio/DRAN overlay, and other carrier-grade wireless solutions. This includes developing sectorization strategies for high-density venues; evaluating uplink and downlink performance, SINR, throughput, and interference; and integrating multiple frequency bands, radio sources, and wireless operators into a coordinated system architecture. The role works closely with customers, wireless carriers, OEM partners, construction teams, and project managers to deliver solutions that meet coverage, capacity, and performance objectives. The System Architect leads complex technical reviews and architectural decisions and owns the technical strategy for advancing designs through carrier approval.
