- 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).
