Senior Network Infrastructure Engineer

Nyla Technology Solutions•Annapolis Junction, MD

10h•$158,000 - $187,000

About The Position

The Senior Network Infrastructure Engineer assists in all phases of network management, from initial architecture design through deployment, operational maintenance, and hardware and software upgrades. The role supports distributed, high-performance software engineering environments by implementing communication system requirements, analyzing network behavior, and resolving complex connectivity issues. An active TS/SCI clearance with polygraph is required. The position requires hands-on enterprise and mission network administration and engineering, including configuring, maintaining, and troubleshooting routers, switches, and firewalls in multi-vendor environments. It also involves analyzing network metrics such as connection time, latency, packet-size distribution, and throughput, and using network verification or digital-twin platforms to create network maps, audit configurations, and map attack surfaces. The role supports Zero Trust Architecture capabilities, including asset discovery, continuous posture monitoring, and network segmentation, as well as communication requirements, VLANs, and interconnects for distributed development frameworks, build pipelines, and developer test environments. The annual base salary range is $158,000–$187,000 USD. Discretionary bonus compensation and a comprehensive benefits package are not included in that range. Actual compensation may vary based on geographic location, work experience, education, skill level, and other factors.

Requirements

Active security clearance at the TS/SCI polygraph level.
Hands-on experience configuring, maintaining, and troubleshooting enterprise or mission network devices, including routers, switches, and firewalls, in multi-vendor environments.
Ability to analyze granular network metrics, including connection time, latency, packet-size distribution, and throughput, using tools such as Wireshark or tcpdump.
Practical experience deploying, configuring, and operating Forward Networks or an equivalent network verification or digital-twin platform.
Technical understanding of Zero Trust security principles, including automated asset discovery, continuous posture monitoring, and network segmentation.
Ability to implement and sustain communication requirements, VLANs, and interconnects supporting distributed development frameworks, build pipelines, and developer test environments.
Bachelor’s degree in Data Analytics, Intelligence Studies, Computer Science, Finance/Economics, or a related discipline, plus 12 or more years of specialized data analytics or financial intelligence experience; or a high school diploma/GED plus 16 or more years of hands-on intelligence analysis, financial tracking, and data discovery experience in lieu of a degree.
