DAS Systems Engineer, Signal Source Solutions

Communication Technology Services (CTS) is an industry leader in in-building and campus cellular managed services through our Forte Neutral Source™ signal source service offering. CTS provides enterprise customers with turnkey, in-building cellular networks providing AT&T, Verizon and T-Mobile signal in any sized building, anywhere in the US. These CTS signal source services support our clients’ mission-critical business applications and wireless connectivity needs.

We are driven by the desire to solve complex customer problems, the excitement of deploying new technologies, and our dedication to providing complex wireless network solutions to customers as simple-to-purchase solutions.

The CTS Forte® signal source team is a national overlay organization to CTS’s nationwide DAS design and deployment teams. The Forte team is seeking a DAS Systems Engineer who blends systems engineering, RF performance optimization, and hands-on commissioning with disciplined project management. You’ll support pre-sales solutioning, project deployment/turn-up, and own post-deployment performance—balancing the DAS and radios, validating KPIs, and ensure multi-carrier acceptance.

What you’ll do

Pre-Sales & Solution Architecture

• Attend pre-sales client meetings and presentations with sales upon request and work with customers to answer questions and provide technical details regarding signal source solutions.
• Translate venue requirements into scalable DAS + neutral-host radio architectures and project-specific BOMs aligned to technical and financial goals.
• Review and iterate iBwave designs for carrier compliance (band plans, MIMO, sectors, head-end topology); propose design refinements to meet coverage, capacity, and zoning constraints.
• Contribute to vendor/technology evaluations and the Forte® signal-source roadmap.

Deployment, Commissioning & Methods of Procedure (MOPs)

• Produce detailed MOPs covering RF, IP, and power for multi-OEM environments (DAS from ADRF, Airspan/Corning, Andrews/CommScope, JMA, SOLiD and radios from Ericsson, Nokia, Samsung, Airspan/Corning, Andrews/Commscope).
• Review field team validation work on the head-end, remotes, and passive infrastructure and ensure their evaluation was complete: line sweeps (return loss/VSWR), PIM testing, attenuation plans, and optical power budgets.
• Stand up backhaul: review IP cut-sheets, define VLANs/QoS, establish IPSec tunnels and firewall rules; troubleshoot routing, NAT, and certificate issues.

Performance Engineering (SPE)

• Coordinate with onsite SPEs and when required, perform the SPE role: Commission and optimize DAS, set gains/AGC, balance UL/DL, manage noise floors, and mitigate PIM/oscillation/pilot pollution.
• Plan oversee the execution of any necessary acceptance testing: e911, Functional Call Test, walk testing. m
• Coordinate multi-carrier integration and acceptance; ensure measurable KPIs (e.g., =95% design-area coverage to spec, session retention targets, throughput) are met with documented reports.

Operations & Support

• Act as the resource for Tier-3 escalation from the CTS NOC; lead complex incident triage and post-mortems.
• Define monitoring baselines and consult with NOC on performance to the baselines, document change control and performance trends for lifecycle upgrades.
• Travel occasionally for critical turn-ups or escalations (nights/weekends possible in mission-critical venues).

What you’ll bring

Required

• 6+ years in in-building wireless with significant time as a DAS Systems Performance Engineer or equivalent systems/optimization role.
• Proficiency across one or more DAS OEMs (ADRF, Corning, CommScope, JMA, SOLiD) and operator-grade small cells (Ericsson, Nokia, Samsung, Airspan/SpiderCloud).
• Strong iBwave skills (L2+ or equivalent) for design review, compliance redlines, and mark-ups.
• Past experience with commissioning/optimization tooling to ensure field teams are performing the work correctly: spectrum analyzers, PIM analyzers, scanner platforms (PCTEL/R&S/Keysight), and walk/drive-test tools (TEMS, XCAL, SeeHawk Touch, etc.).
• Solid Layer-3/IP fundamentals: VLANs, routing, IPSec, certificates, and firewall policy for carrier integrations.
• Demonstrated project execution in multi-site programs with remote field teams; excellent documentation and stakeholder communication.

Preferred

• OEM certifications (any of ADRF/Corning/CommScope/JMA/SOLiD) and operator integration experience with AT&T, Verizon, and T-Mobile processes.
• Experience with DAS-alternative neutral-host architectures (Ericsson Radio Dot, Nokia AirScale).
• Familiarity with element management system platforms and KPI dashboards; scripting/automation for data reduction/reporting is a plus.
• BS/BA in Engineering (or equivalent experience in RF/DAS systems).

Work Setup
100% remote within the contiguous U.S., with periodic travel for key deployments and escalations.
