Network Engineer- CBP

Work Location: Springfield, VA (onsite)

Travel Requirement: Up to 25%

Citizenship: US Citizenship required

Security Clearance: Must possess existing DHS suitability (EOD) or active Secret clearance

The Network Engineer supports the U.S. Customs and Border Protection (CBP) Operational Technology Operations Center (OTOC) and the design, implementation, testing, deployment, operation, and sustainment of network infrastructure supporting the Office of Information and Technology (OIT) ISS OTOC. This is a full-time onsite position focused on network engineering, secure connectivity, Watchtower Mobile Device Management (MDM), laboratory validation, and field support for operational technology during an assigned 8-hour day shift.

The Network Engineer designs, configures, implements, validates, troubleshoots, documents, and sustains secure network infrastructure supporting OT and tactical systems across laboratory, enterprise, edge, cloud, and field environments. The position engineers solutions using routers, switches, firewalls, VPNs, wireless networks, network services, cloud connectivity, identity and certificate services, and endpoint technologies to provide reliable, resilient, and secure end-to-end communications.

The position provides hands-on network engineering support for Watchtower and associated Android, Windows, Linux, iOS, radio, sensor, wearable, and tactical endpoints; develops representative lab environments; performs network validation and acceptance testing; supports deployment readiness and technology fielding; and resolves complex network, performance, and interoperability issues. The Network Engineer coordinates with systems integrators, cybersecurity, engineering, OTOC operations, program leadership, vendors, and government stakeholders to implement and sustain approved network solutions in operational environments.

Responsibilities:

Network Engineering and Architecture

• Design, configure, implement, test, troubleshoot, optimize, and document network solutions supporting OTOC, Watchtower, operational technology, and tactical systems.
• Configure and support routers, switches, firewalls, VPN gateways, wireless infrastructure, and associated network services in lab and operational environments.
• Support IPv4/IPv6 addressing, subnetting, VLANs, routing, switching, NAT, DNS, DHCP, VPNs, access control, and secure network segmentation.
• Engineer network connectivity across on-premise, cloud, edge, mobile, and disconnected or limited-connectivity environments.
• Analyze network paths and dependencies to identify connectivity, latency, packet loss, routing, name-resolution, firewall, VPN, or configuration issues.
• Use packet captures, logs, monitoring platforms, command-line tools, and other network diagnostic methods to isolate and resolve complex problems.
• Develop and maintain network diagrams, IP address plans, interface definitions, configuration baselines, port/protocol matrices, build records, and implementation documentation.
• Maintain network configuration management, backups, version control, standards, configuration baselines, and repeatable deployment practices.
• Engineer and review network changes for technical dependencies, capacity and performance impacts, security considerations, validation requirements, implementation sequencing, and rollback needs.

Watchtower and Operational Technology Networking

• Provide network engineering and connectivity support for the Watchtower MDM platform and supported OT and tactical devices.
• Validate network requirements for Android, Windows, Linux, iOS, radios, sensors, wearables, and other supported endpoints.
• Support device enrollment, provisioning, policy delivery, certificate distribution, remote management, compliance reporting, and over-the-air updates by ensuring required network paths and services are available.
• Validate Watchtower communications across enterprise, wireless, VPN, cloud, edge, offline, and disconnected-use scenarios.
• Troubleshoot connectivity between Watchtower services, managed endpoints, identity services, certificate infrastructure, cloud resources, and other integrated systems.
• Support secure communications architectures and certificate-based connectivity using PKI, X.509 certificates, Certificate Authorities, and client/server certificate lifecycle processes.

Network Laboratory Engineering and Testing

• Build, configure, and maintain representative network lab environments used to evaluate new technologies, network configurations, devices, software releases, and integration changes before operational fielding.
• Develop and execute network connectivity, interoperability, performance, failover, regression, and operational acceptance test procedures.
• Reproduce field network issues in the lab, collect diagnostic data, isolate root causes, validate fixes or workarounds, and document results.
• Validate routing, firewall rules, VPN connectivity, DNS/DHCP services, certificates, wireless connectivity, bandwidth requirements, and endpoint communications before deployment.
• Test network behavior under representative operational conditions, including degraded, edge, intermittent, or disconnected connectivity when applicable.
• Document test objectives, topology, configurations, procedures, results, defects, limitations, corrective actions, and deployment-readiness findings.
• Coordinate network test events with Systems Integrators, cybersecurity, OTOC support personnel, vendors, and government stakeholders.

Network Implementation and Field Deployment

• Engineer and support the staging, configuration, validation, implementation, deployment, and fielding of network-enabled technologies to operational locations.
• Perform site and deployment readiness assessments to identify network connectivity, addressing, routing, firewall, VPN, wireless, power, rack/space, and other infrastructure dependencies.
• Prepare network configurations, deployment packages, diagrams, implementation plans, test checklists, validation procedures, and rollback procedures.
• Perform pre-deployment verification of network devices, firmware/software versions, configurations, certificates, accounts, connectivity, and external dependencies.
• Provide onsite or remote network support during installation, activation, acceptance testing, and transition to operations.
• Troubleshoot field network issues and coordinate corrective actions with systems integration, cybersecurity, carriers/service providers, vendors, and OTOC support teams.
• Capture as-built network configurations, fielding results, lessons learned, known issues, and follow-on actions.
• Support transition of fielded technology to OTOC operations by providing network documentation, troubleshooting guidance, knowledge transfer, and escalation procedures.

Network Operations, Security, Performance, and Sustainment

• Monitor and assess network health, availability, utilization, performance, and connectivity using approved tools and methods.
• Provide Tier 2/Tier 3 network engineering support for incidents and problems requiring advanced protocol analysis, lab reproduction, configuration changes, performance analysis, or engineering coordination.
• Support incident, problem, and change management activities associated with network infrastructure, integrated systems, releases, deployments, and configuration changes.
• Perform root cause analysis for recurring or high-impact network issues and develop documented corrective and preventive actions.
• Coordinate with cybersecurity personnel to implement approved network security controls, segmentation, access restrictions, secure protocols, and remediation actions.
• Support network device lifecycle activities, including configuration, upgrades, patching, firmware updates, backup/restore, replacement, and decommissioning in accordance with approved processes.
• Maintain technical documentation, SOPs, troubleshooting guides, knowledge articles, network standards, and operational procedures.
• Provide technical briefings, demonstrations, knowledge transfer, and hands-on training to OTOC support personnel and government stakeholders as required.
