Position Overview

CarverBeth is seeking a highly experienced Time Division Multiplexing (TDM) Elimination Subject Matter Expert (SME) to support large-scale modernization efforts across the Defense Information Systems Network (DISN) . This role is critical to the successful transition of legacy TDM-based systems (e.g., SONET, Promina, MSPP) to next-generation IP and optical transport architectures. The ideal candidate will serve as a senior technical leader responsible for engineering, integration, and execution of circuit migrations, enabling the DoD's transition to a modern, resilient, and high-capacity transport network .

Primary Responsibilities

• Technical Leadership & Engineering Serve as senior SME for TDM elimination and DISN IP optimization efforts
• Develop and implement strategies to eliminate legacy TDM interfaces (e.g., RS-232, RS-530, SONET) Lead the removal and decommissioning of legacy platforms including: Optical Digital Cross Connect (ODXC) Multi-Service Provisioning Platforms (MSPP) ADTRAN multiplexers
• Design and implement circuit emulation solutions to translate TDM traffic into Ethernet/IP Network Engineering & Site-Specific Design Produce detailed engineering deliverables on a site-by-site basis , including: Identification of sites requiring circuit emulation devices
• Development of migration solutions to Ethernet/IP architectures
• Integration with DISA Joint Provider Edge (J-PE) and Optical Transport Network (OTN) Equipment configuration, rack elevations, and buildout requirements
• Identification of network dependencies (capacity, ports, DCN, etc.)
• Develop Methods of Procedure (MOPs) and transition sequencing strategies
• Implementation & Field Support Conduct global site surveys to determine infrastructure requirements, including: Power, grounding, and rack space
• Fiber/copper cabling infrastructure
• Data Communications Network (DCN) integration
• Develop Bills of Materials (BOMs) to support procurement and implementation
• Provide engineering support during provisioning, installation, and turn-up activities
• Program Integration & Execution Analyze requirements to identify engineering gaps, risks, and discrepancies , and develop
• Courses of Action (COAs) Support program management activities including: Schedule tracking and milestone alignment
• Identification of critical path risks and mitigation strategies
• Coordinate with cross-functional teams, mission partners, and external stakeholders to ensure execution success
• Strategic Planning & Architecture Compile and analyze existing network architectures to define future-state
• Ethernet/IP transport strategies
• Support development of next-generation transport solutions aligned with DoDIN modernization objectives
• Provide technical input to optimize cost, performance, and network resiliency
• Customer Engagement & Reporting Lead customer outreach and coordination to support circuit transition planning
• Prepare and deliver technical briefings, status updates, and performance metrics
• Provide technical reviews of Government documentation and configuration management processes
• Represent CarverBeth as a technical authority in meetings with DISA and mission partners
• Continuous Improvement Drive improvements in service delivery, cost efficiency, and execution timelines
• Recommend innovative solutions to accelerate TDM migration and reduce operational risk
