Senior Network Engineer

F5 is a company striving to enhance the digital world by empowering organizations to create, secure, and run applications. They are seeking a Senior Network Engineer to deliver reliable, scalable network services across multi-region and global environments, focusing on network reliability, performance, and incident response.

Responsibilities:

• Engineer, build, operate, and deliver network solutions for global data centers, cloud platforms, FedRAMP-authorized environments, build environments, and product connectivity needs
• Engineer and optimize routing for a global IP backbone, including multi-region route propagation, redundancy, and traffic-engineering strategies
• Engineer, build, and operate scalable, highly available L3 topologies using BGP, OSPF, and robust routing policy (communities, AS-path manipulation, MED/local-pref tuning, ECMP, route-reflector hierarchy)
• Design and implement secure network segmentation, boundary controls, and traffic isolation required for FedRAMP Moderate/High environments
• Implement hybrid and cloud-native routing across AWS/Azure/GCP using Direct Connect, ExpressRoute, VPN, Transit Gateway, Virtual WAN, and cloud router constructs—ensuring alignment with FedRAMP architectures and security control requirements
• Develop and maintain automated provisioning, configuration, compliance, and validation pipelines using Python, Ansible/AWX, and Git-driven CI/CD workflows, including FedRAMP configuration baselines
• Ensure connectivity, availability, and performance across multi-region data centers, backbone sites, cloud platforms, and regulated FedRAMP environments using proactive monitoring, telemetry, and lifecycle management practices
• Operate networks in accordance with FedRAMP continuous monitoring requirements, including configuration drift detection, vulnerability mitigation, and audit readiness
• Troubleshoot complex routing, TCP, and connectivity issues using tools such as netcat, ping/ICMP, logs, and packet captures
• Lead or support major incident response when needed, including FedRAMP-relevant incident handling, escalation, and reporting procedures
• Execute changes, upgrades, and migrations safely using structured procedures (MOPs), documented approvals, automated workflows, and validated rollback mechanisms
• Remediate vulnerabilities and maintain compliance across network OS versions, configurations, firmware, and security posture in coordination with Security and Compliance teams
• Engineer enhancements, new capabilities, and service-driven connectivity features supporting product, platform evolution, and FedRAMP boundary services
• Design automation that enforces least privilege, segmentation, encryption-in-transit, logging, and configuration compliance for regulated environments
• Replace manual operational steps with automated workflows incorporating pre/post-checks, compliance gates, evidence collection, and safe-rollback logic
• Test new network OS versions, automation logic, routing changes, and security controls in controlled environments prior to production and FedRAMP deployment
• Partner with Build, Engineering, Architecture, Product, Security, and Compliance teams to ensure reliability, scalability, and alignment with FedRAMP control objectives
• Translate product, regulatory, and platform requirements into network designs that meet FedRAMP architectural and security expectations with clear timelines and dependencies
• Conduct capacity planning across links, devices, cloud gateways, backbone segments, routing domains, and FedRAMP boundary components
• Manage procurement cycles, RMA workflows, vendor escalations, and equipment lifecycle, ensuring vendors and solutions support FedRAMP use cases
• Evaluate vendor technologies for performance, resiliency, automation compatibility, FedRAMP eligibility, and cost-effectiveness
• Create and maintain high-quality runbooks, architectural diagrams, and troubleshooting guides, including FedRAMP boundary diagrams and network control documentation
• Maintain accurate documentation required for FedRAMP audits, assessments, and continuous monitoring activities
• Define lifecycle standards for network roles, routing constructs, appliances, and platform components
• Ensure monitoring, alerting, and operational procedures are documented, auditable, and continuously improved
• Mentor engineers through structured troubleshooting, technical deep dives, FedRAMP design considerations, and post-incident learning sessions

Requirements:

• Bachelor's degree in Computer Science, Information Technology, or related field (Master's preferred)
• 10+ years in network engineering with experience in large-scale, multi-region, and global routing environments
• Experience engineering, operating, or supporting FedRAMP Moderate and/or High environments is strongly preferred
• Deep hands-on expertise with BGP and OSPF in global IP backbone environments, including traffic engineering and multi-vendor interoperability
• Strong operational and engineering experience with JunOS (MX, QFX, SRX preferred)
• Proficiency with additional network OS platforms (e.g., EOS, NX-OS, IOS-XE) is a plus
• Strong troubleshooting across routing, switching, TCP/IP, asymmetric paths, latency, packet loss, MTU/fragmentation, and QoS behaviors
• Experienced with hybrid cloud and cloud-native networking across AWS, Azure, and/or GCP
• Hands-on automation skills using Python, Ansible/AWX, configuration templating, Git workflows, and automated testing/validation pipelines
• Strong understanding of network security controls, boundary protection, encryption, logging, and segmentation concepts required for FedRAMP
• Familiarity with firewalls, VPNs, DDoS mitigation, IDS/IPS, and NIST 800-53-based security frameworks
• Strong incident leadership skills, able to coordinate cross-functional teams under pressure
• Excellent written and verbal communication across Architecture, Product, Security, Compliance, Operations, and Build teams
• Ability to mentor and elevate peers and junior engineers
• Effective in fast-paced environments with competing priorities and regulatory constraints
• Strong analytical thinking, structured problem-solving, and continuous-improvement mindset
• Reinforces a positive culture and demonstrates our expectation to 'be kind.'
