Network Engineer- Active Secret Clearance Required

The Network Engineer will provide technical expertise in the engineering, operation, and sustainment of metropolitan-area fiber transport systems using Dense Wavelength Division Multiplexing (DWDM), ring-based fiber topologies, and network architectures such as Optical Transport Network (OTN) technology and SONET/SDH. This role supports mission-critical enterprise transport services across Department facilities, ensuring resilient, secure, and high-performance connectivity between IT networks., * Engineer, maintain, and troubleshoot DWDM optical transport systems supporting metropolitan-area networks, including power levels, optical budgets, wavelength assignments, and fault isolation.

• Support the reliable operation of fiber-optic ring networks, including monitoring of protection switching, managing topology changes, and ensuring continuity of critical data paths.
• Diagnose transport-layer events using carrier-grade telemetry, alarm structures, and diagnostic indicators analogous to SONET (LOS, LOF, AIS, RDI, etc.).
• Develop and maintain documentation, diagrams, optical power logs, wavelength plans, and standard operating procedures.
• Provide technical input for modernization efforts involving fiber plant upgrades, DWDM system enhancements, or new optical routes.

• 5+ years of experience engineering, operating, and troubleshooting carrier-grade optical transport networks, DWDM systems, or fiber-based metropolitan-area transport infrastructures.
• 5+ Years of Tier 2-3 Network Engineering and Administration.
• Engineering familiarity with enterprise network routing and switching systems for LAN/WAN connectivity
• Hands-on experience with DWDM transport systems, optical amplifiers, multiplexers/demultiplexers, transponders, and ROADM-class equipment
• Understanding of metropolitan fiber-optic ring topologies, protection schemes, and failover mechanisms (e.g., UPSR/BLSR-style concepts and OTN equivalents: ODUk (Optical Data Unit) sub-layer protection mechanisms and ODU-MS/RING protection.)
• Knowledge of legacy or carrier-grade transport protocols analogous to Optical Transport Network (OTN) technology framing, alarms, and OAM functions
• Experience working with carrier transport systems during migration phases (e.g., transitioning services between backbone networks or protected optical segments)
• CCNA, JNCIA/JNCIS, Ciena, Infinera, Nokia Optical, or equivalent networking/optical transport certification preferred.
• Must be a U.S. citizen with an Active Secret Clearance.
