Headquartered in McLean, VA, By Light supports defense, civilian, and commercial IT customers worldwide.

The Technical Project Manager (TPM) – DISA / PEO Transport Specialization – will lead the execution of complex technical programs supporting the Defense Information Systems Agency (DISA), with a primary focus on PEO Transport initiatives. This role requires deep expertise in optical transport, IP networking, network design and engineering, and implementation services across large‑scale DoD environments. The TPM will serve as a customer‑facing technical leader, directly engaging DISA stakeholders to ensure successful delivery of mission‑critical network modernization and transport‑layer capabilities.

The ideal candidate combines hands‑on engineering credibility with disciplined program leadership, enabling them to guide cross‑functional teams, coordinate with DISA program offices, and ensure solutions meet stringent technical, operational, and cybersecurity requirements.

• Lead end‑to‑end program management for DISA and PEO Transport initiatives involving optical transport, IP networking, and enterprise network modernization.
• Develop and maintain integrated master schedules, risk management plans, and execution roadmaps aligned with DISA’s technical and operational priorities.
• Drive program milestones, engineering reviews, deployment readiness, and acceptance activities across internal engineering teams, vendors, and DISA stakeholders.
• Ensure all deliverables meet DISA technical standards, cybersecurity controls, and mission assurance requirements.

• Serve as the primary technical program interface with DISA PEO Transport, including engineering leads, program managers, and operational stakeholders.
• Conduct technical exchange meetings, design walkthroughs, and implementation planning sessions directly with DISA personnel.
• Provide clear, consistent communication of program status, risks, dependencies, and mitigation strategies to DISA leadership and internal executives.
• Build trusted relationships with DISA engineering teams to support long‑term program success and future modernization initiatives.

• Provide technical leadership across optical networking (DWDM, OTN, ROADMs, 100G/400G transport), IP routing/switching, and network architecture.
• Support troubleshooting, root‑cause analysis, and escalation management during deployment and sustainment phases.
• Ensure engineering solutions align with DISA’s enterprise architecture, transport‑layer strategy, and cybersecurity frameworks.

• Oversee implementation activities including site surveys, rack/stack, optical turn‑ups, IP configuration, testing, and operational acceptance.
• Coordinate with vendors and OEMs for optical platforms, network hardware, and supporting technologies.
• Ensure all deployments adhere to DISA change management processes, security controls, and operational readiness requirements.

• Partner with engineering, operations, logistics, contracts, and security teams to ensure seamless program execution.
• Support proposal development, BOE creation, and technical inputs for DISA opportunities as needed.
• Mentor junior engineers and project staff, fostering a culture of technical excellence, disciplined execution, and customer focus.

• 10+ years of experience in network engineering, optical transport, or IP architecture roles.
• 5+ years of experience managing technical programs or large‑scale implementations for DISA, with direct engagement at PEO Transport strongly preferred.
• Demonstrated experience delivering optical, IP, or network modernization projects within classified or mission‑critical DoD environments.
• Deep knowledge of optical networking technologies (DWDM, OTN, ROADMs, 100G/400G transport).
• Strong expertise in IP networking (BGP,…
