POSITION SUMMARY

Constellis is seeking an experienced Field Network Engineer to support the Layered Extended Security Operations (LEXSO™) program. The engineer will work remotely when not supporting field activities but must be prepared to travel frequently to customer sites, test locations, demonstrations, installations, and other LEXSO operational environments. Travel requirements may vary significantly based on deployment schedules and customer needs.

LEXSO is an advanced, sensor-agnostic security technology platform that integrates sensors, communications, edge computing, networking, and automation into a unified operational environment. The platform is designed to integrate existing and new technologies into scalable architectures supporting critical infrastructure, defense, government, and other high-value facilities.

We are looking for a technically strong, hands-on engineer who is equally comfortable configuring a managed switch, troubleshooting a VLAN, installing and testing copper or fiber infrastructure, installing a sensor in the field, configuring a communications link, or working inside a server rack. The successful candidate must be capable of deploying to customer and test locations, working independently or as part of a small technical team, and troubleshooting complex systems under real-world field conditions.

RESPONSIBILITIES

  • Design, configure, deploy, and troubleshoot IP networks supporting LEXSO systems.
  • Install and configure routers, managed switches, firewalls, wireless systems, VPNs, and other network infrastructure.
  • Establish and maintain connectivity between sensors, servers, edge-compute systems, communications equipment, and the LEXSO platform.
  • Configure and troubleshoot VLANs, subnets, routing, DHCP, DNS, NAT, VPNs, firewall rules, and related network services.
  • Install, test, troubleshoot, and maintain copper and fiber-optic network infrastructure used to connect sensors, communications systems, compute infrastructure, and remote field equipment.
  • Work with single-mode and multimode fiber, SFP/SFP+ transceivers, media converters, fiber patch panels, and associated optical networking equipment.
  • Perform fiber troubleshooting using appropriate test equipment and understand common causes of optical-link degradation and failure.
  • Integrate field sensors including IP cameras, radar, LiDAR, unattended ground sensors, UAS/drone systems, counter-UAS systems, environmental sensors, and other IP-connected devices.
  • Install, configure, cable, and troubleshoot server racks, compute nodes, UPS systems, network appliances, patch panels, and associated infrastructure.
  • Support terrestrial, cellular, wireless, microwave, fiber-optic, and satellite communications used to connect distributed LEXSO systems.
  • Perform structured network troubleshooting using packet captures, network analysis tools, device logs, command-line utilities, and vendor diagnostic tools.
  • Diagnose connectivity, latency, packet loss, multicast, bandwidth, addressing, optical-link, power, and physical-layer issues.
  • Conduct site surveys and help develop network, communications, power, fiber, and equipment-placement plans for new deployments.
  • Configure equipment in laboratory and staging environments before field deployment.
  • Perform equipment installation, commissioning, operational testing, troubleshooting, and acceptance activities at customer sites.
  • Document network architectures, IP addressing, VLANs, equipment configurations, rack layouts, fiber and copper cable paths, and field changes.
  • Maintain accurate configuration records and deployment documentation.
  • Coordinate directly with software engineers, DevOps, sensor-integration engineers, field operations personnel, vendors, and customer technical teams.
  • Support demonstrations, operational exercises, system testing, and rapid deployments.
  • Identify field problems, determine root cause, implement corrective actions, and clearly communicate findings to the engineering team.
  • Provide remote technical support and troubleshooting for deployed LEXSO systems between field assignments.
  • Business work hours are Monday-Friday standard core hours, however some extended or weekend hours may be required.
  • Both domestic and international travel required for this role up to 60%

QUALIFICATIONS

  • Demonstrated 7 years of experience with enterprise and field-based IP networking environments.
  • Proven ability to configure, maintain, and troubleshoot Layer 2 and Layer 3 network infrastructure.
  • Strong understanding of VLANs, routing, switching, subnetting, DHCP, DNS, NAT, VPNs, and firewall technologies.
  • Experience deploying and supporting managed Ethernet switches and routers.
  • Knowledge of copper and fiber-optic Ethernet infrastructure, including installation and maintenance best practices.
  • Familiarity with both single-mode and multimode fiber-optic systems and their applications.
  • Experience working with SFP and SFP+ transceivers, optical links, fiber patching, connectors, and fiber distribution equipment.
  • Ability to install, inspect, clean, test, and troubleshoot fiber-optic cabling and related components.
  • Proficiency using fiber test equipment, including optical power meters, visual fault locators (VFLs), and optical time-domain reflectometers (OTDRs).
  • Experience utilizing network testing and diagnostic tools to identify and resolve connectivity and performance issues.
  • Working knowledge of Wireshark or comparable packet analysis tools for network troubleshooting and traffic analysis.
  • Strong understanding of TCP/IP and UDP-based networking systems and protocols.
  • Experience supporting wireless networking solutions and point-to-point communication systems.
  • Familiarity with secure remote access technologies, including WireGuard, IPsec, and other VPN solutions.
  • Proficiency with Linux operating systems and command-line based troubleshooting techniques.
  • Experience installing and configuring server racks, network racks, and associated infrastructure.
  • Knowledge of UPS systems and power distribution equipment supporting critical IT environments.
  • Experience integrating and supporting IP-based cameras, sensors, IoT devices, and other network-connected field equipment.
  • Ability to read, create, and maintain network diagrams, rack diagrams, wiring schematics, fiber maps, and technical documentation.
  • Preferred experience:
  • Physical security systems and security-system integration.
  • Surveillance camera and video-management systems.
  • Radar and LiDAR systems.
  • UAS or counter-UAS technologies.
  • Unattended ground sensors.
  • Satellite communications, including Starlink or similar systems.
  • Microwave or point-to-point wireless communications.
  • Cellular communications and multi-WAN networking.
  • Fiber-optic backbone and long-distance communications infrastructure.
  • Fiber termination, fusion splicing, OTDR testing, and optical-link troubleshooting.
  • Edge computing and GPU/server infrastructure.
  • Industrial or critical-infrastructure networking.
  • Government or Department of Defense environments.
  • Remote-site networking and communications.
  • Network monitoring and observability.
  • High-availability and redundant network architectures.
  • Portable or rapidly deployable communications systems.
