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
Basic Qualifications
- Minimum 10+ years of experience in telecommunications engineering or network modernization
- Deep expertise in:
- TDM technologies (SONET, Promina, MSPP, ODXC)
- Circuit-to-packet migration and circuit emulation
- Optical transport and IP networking architectures
- Proven experience supporting large-scale DoD or DISN network environments
- Strong understanding of:
- TSO's, TCOSS, and DISA circuits/leases
- Ethernet/IP networking
- Optical transport (OTN, DWDM)
- Joint Provider Edge (J-PE) integration
- Experience developing:
- Engineering design packages
- Methods of Procedure (MOPs)
- Bills of Materials (BOMs)
- Active Secret clearance with ability to obtain/maintain Top Secret
Preferred Qualifications
- Direct experience supporting DISA TDM elimination or IP optimization programs
- Familiarity with:
- SEANet (Serial-to-IP Edge Adaptation)
- CTP (Circuit-to-Packet) and NGT-E technologies
- Ciena 6500, Cisco 15454, Sycamore SN9K
- Background in global network implementation and site survey execution
- Strong program integration and stakeholder coordination experience
- Experience briefing senior government leadership and technical stakeholders
