Job Description
Signature Federal Systems seeks a motivated, mission-focused Senior Principal Cyber Engineer (Network Focus) to join our team in Chantilly, VA.
In this role, you will provide advanced engineering expertise to design, implement, secure, and sustain
complex enterprise network environments supporting critical customer missions. You will collaborate
across technical teams and customer stakeholders to deliver resilient, highly available, and secure
network solutions while driving operational excellence and innovation.
Responsibilities include but are not limited to:
• Interact with engineers, cross-functional teams, and customers at multiple levels to gather,
coordinate, and deliver technical information.
• Work closely with engineering teams to troubleshoot and build complex, highly available network
topologies.
• Develop and manage comprehensive network monitoring and alerting strategies leveraging SNMP,
flow analytics, packet inspection, and infrastructure telemetry to proactively identify performance
degradation, capacity constraints, and service disruptions across complex enterprise and
mission-critical environments.
• Lead complex network troubleshooting and root cause analysis across enterprise, data center,
cloud, and hybrid environments, utilizing packet captures, routing analysis, traffic flow inspection,
and protocol level diagnostics to rapidly identify and resolve service-impacting issues.
• Perform engineering support and system administration for applications and systems, including
installation, configuration, maintenance, patching, and backup/restore activities.
• Provide Tier 2/3 maintenance and engineering support for deployed network and cybersecurity
technologies.
• Support Assessment and Authorization (A&A) activities related to cybersecurity technologies,
where applicable.
• Develop and implement automation solutions for repetitive project tasks and metrics collection
using scripting, supporting testing and production deployment.
• Perform additional project and corporate duties as assigned to support customer mission
requirements.
Minimum Qualifications:
• Bachelor’s degree or 4+ additional years of IT experience in lieu of degree.
• 10+ years of experience in cybersecurity or network engineering.
• Proficiency in configuring and optimizing routing protocols like BGP and OSPF.
• Direct experience implementing network virtualization and encapsulation technologies (EVPNVXLAN,
MPLS).
• Solid understanding of traffic management and security perimeter defenses, including load
balancers, firewalls, and virtualized infrastructure.
• Experience troubleshooting web application traffic to include a strong understanding of HTTPS
transactions and mutual TLS (mTLS).
• Strong understanding of Windows and Linux systems, operating system security practices, and
network security concepts.
• Experience deploying, upgrading, and troubleshooting multi-vendor network equipment and
solutions, such as Juniper, Palo Alto, F5, and Nutanix.
• Experience leveraging SNMP monitoring tools.
• Must have or be willing to obtain an IAT Level II (or higher) certification within 6 months of hire.
Preferred Qualifications:
• Knowledge of Cross Domain Solutions (CDS) technologies on the NCDSMO approved products
list.
• Understanding of architectural principles such as defense in depth, resilience, and integrated
security operations.
• Familiarity with federal cybersecurity guidance, including NIST SP 800-37 (Risk Management
Framework) and NIST SP 800-137 (Information Security Continuous Monitoring).
• In-depth understanding and practical experience with LANs, firewalls, routers, and switches.
• Experience working in Agile environments.
Clearance Requirements:
• Must possess an active TS/SCI with Polygraph.
Physical Requirements:
• Must be able to remain in a stationary position 50% of the time.
• Must occasionally move about inside the office to access file cabinets, office machinery, or
communicate with co-workers, management, and customers via email, phone, or virtual
platforms, which may involve delivering presentations
