TDM Elimination Subject Matter Expert

Location: DISA Scott or Fort Meade
Clearance Required: Active Secret (Top Secret Eligible/Preferred)
Travel: 10% - Rare, but may be required to support customer meetings

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
