Responsibilities:
The Field Engineer is responsible for deploying, configuring, and sustaining network and systems infrastructure at customer and program sites across the United States. This role carries the technical depth of a systems engineer but applies it in the field, where the engineer is frequently the only technical presence on site and must diagnose and resolve issues independently. Success requires a strong hands-on foundation across networking, server administration, and endpoint support, combined with the customer-facing judgment and adaptability to work effectively in unfamiliar environments under schedule pressure.
Field Deployment & Site Operations
- Travel to customer and program locations throughout the United States to perform installations, system deployments, and infrastructure build-outs.
- Conduct site surveys to assess power, space, connectivity, and environmental requirements in advance of deployment.
- Rack, cable, and configure network and server hardware, validating functionality prior to turnover.
- Execute customer handoff procedures, including acceptance testing, walkthroughs, and end-user orientation.
- Serve as the on-site technical point of contact during active deployments, coordinating with remote engineering staff as needed.
Network Infrastructure
- Configure and troubleshoot routers, switches, firewalls, and wireless infrastructure to established program baselines.
- Establish and validate site connectivity, including VPN tunnels, circuit turn-up, and remote access.
- Diagnose network faults on site using structured troubleshooting methods and escalate complex issues with clear supporting detail.
- Verify network performance and security configuration against program standards before closing out a deployment.
Systems & End User Support
- Install, configure, and maintain Windows and Linux servers, workstations, and virtualization hosts.
- Perform system administration tasks including account provisioning, access control, patching, and backup verification.
- Support end users on site and remotely, resolving hardware, software, mobile device, and peripheral issues.
- Deploy and configure imaging, endpoint management, and software distribution tooling.
Security & Compliance
- Apply security baselines and hardening standards to deployed systems and network devices.
- Maintain accountability for equipment, media, and sensitive material while in transit and on site.
- Follow established change control and configuration management procedures for all field modifications.
- Report security concerns and anomalies encountered in the field through appropriate channels.
Documentation & Collaboration
- Produce accurate as-built documentation, site records, network diagrams, and trip reports following each engagement.
- Contribute to installation guides, runbooks, and knowledge base articles that improve repeatability across sites.
- Coordinate with Systems Engineers, Network Engineers, and program management to align field execution with technical design.
- Provide informal guidance and on-the-job training to Technical Associates supporting field operations.
Required Qualifications:
- Associate’s degree in Information Technology, Computer Science, or a related field OR 4+ additional years relevant experience in lieu of education.
- 3+ years of relevant experience in field operations, IT infrastructure, or systems and network administration.
- Hands-on experience configuring and troubleshooting network hardware, including routers, switches, and firewalls.
- Working knowledge of Windows and Linux administration and virtualization platforms.
- Demonstrated ability to work independently at remote sites with limited supervision or on-site support.
- Willingness and ability to travel frequently to field locations throughout the United States, including extended on-site assignments.
- Valid driver’s license and ability to obtain and maintain a passport.
Desired Qualifications:
- Bachelor’s degree in Information Technology, Computer Science, or a related field.
- Certifications such as CCNA, Security+, or Network+.
- Experience with multi-site deployments or distributed infrastructure programs.
- Experience with air-gapped, isolated, or closed network environments in secure settings.
- Experience supporting secure communications and VTC infrastructure.
- Familiarity with structured cabling, power distribution, and rack layout practices.
Key Competencies:
- Broad hands-on technical capability across network, systems, and endpoint domains
- Strong troubleshooting skills in unfamiliar environments and under schedule pressure
- Self-sufficiency and sound judgment when operating without immediate technical backup
- Professional customer-facing presence and clear communication with non-technical users
- Disciplined documentation habits and attention to detail
- Adaptability, resourcefulness, and comfort with frequent schedule changes
