The ideal candidate will have 4-6 years of firsthand experience with firewall administration, load balancer configuration, and network troubleshooting, with a strong understanding of network protocols and security best practices.

Key Responsibilities:

• Manage and troubleshoot complex Layer 3 networks using TCP/IP, OSPF, EIGRP, and BGP.
• Architect, deploy, and manage advanced firewall solutions (e.g., Palo Alto, Cisco ASA, Juniper SRX, Checkpoint) to secure enterprise networks.
• Design and optimize load balancer configurations (e.g., F5 BIG-IP LTM/GTM) for high availability, scalability, and application performance.
• Implement complex IPsec/SSL VPNs, zero-trust security models, and advanced threat prevention mechanisms.
• Lead firewall policy optimization, log analysis, and performance tuning to meet security and compliance requirements.

Required Skills:

• Advanced expertise in Layer 3 networking (TCP/IP, OSPF, EIGRP, BGP).
• Strong proficiency in NAT, IPv4, and firewall operations (TCP/UDP).
• Design, implementation and migration experience on CISCO and Juniper switches and Routers.
• Extensive experience in cloud network troubleshooting (GCP and AWS required).
• Proficiency in change management and operational support processes.
• Ability to mentor and lead technical initiatives.

Qualifications:

• Bachelor's degree in computer science, IT, or related field.
• 5-8 years of progressive experience in network engineering, with at least 2 years focused on firewall administration and 3 years on load balancer technologies.
• Experience with enterprise-grade platforms like F5 BIG-IP (LTM, GTM, ASM, APM), Palo Alto, Fortinet, or Cisco Firepower.
• Proven track record in leading network service transitions, migrations, or large-scale deployments.
• Hands-on experience with cloud-native security and load balancing solutions (e.g., AWS ALB/ELB, Azure Load Balancer).
• F5 Certified Technology Specialist (301a/b, 401), Palo Alto PCNSE, Cisco CCNP Security or equivalent.
• Advanced certifications like CISSP, CISM, CCIE Security, or ITIL Foundation are highly desirable
