Role Description We’re looking for a Senior Network Engineer who dominates cloud networking — someone who can design, secure, and scale complex, global environments across AWS, Azure, and GCP with total confidence. This isn’t a routine admin job — this is for the person who owns the network layer of a modern cloud-first enterprise. You’ll lead the charge on F5 load balancing, next-gen firewalling (Palo Alto and FortiGate), and cloud interconnect design, ensuring high availability, zero downtime, and airtight security. If your idea of “troubleshooting” involves packet captures in one window and Terraform scripts in another, you’ll fit right in. What You’ll Do: - Design, build, and optimize cloud-native network architectures across AWS, Azure, and GCP. - Engineer multi-cloud connectivity — Direct Connect, ExpressRoute, and Interconnect — for high-performance, redundant global networks. - Own F5 in the cloud (BIG-IP VE / NGINX / Distributed Cloud) for advanced load balancing, traffic management, and security. - Lead firewall strategy across Palo Alto (Panorama, GlobalProtect) and Fortinet FortiGate for segmentation, VPNs, and advanced threat protection. - Architect and secure VPCs, VNets, and shared service models — routing, peering, NAT, and private connectivity. - Integrate Cisco virtual appliances and cloud-native routing solutions for scalable, secure interconnectivity. - Automate everything — leverage Python, Ansible, or Terraform to enforce consistency and speed up deployments. - Monitor and optimize performance across hybrid and multi-cloud networks using advanced observability and telemetry tools. - Lead incident response and root cause analysis for complex network or connectivity issues. - Collaborate cross-functionally with Cloud, Security, and DevOps teams to ensure seamless integration and security alignment. Qualifications - 7+ years of experience in network engineering, with 3+ years focused on cloud networking. - Deep hands-on expertise with Azure (VNets, NSGs, Front Door, peering, route tables, Private DNS). - Strong experience with AWS (VPCs, Transit Gateway, Route 53) and GCP (VPCs, Interconnect, Cloud DNS). - Master-level skills in F5 BIG-IP VE, NGINX, or F5 Distributed Cloud. - Proven experience managing Palo Alto and FortiGate in cloud deployments. - Advanced routing and security knowledge — BGP, IPSec, GRE, NAT, segmentation, and high-availability designs. - Scripting and automation skills (Python, Ansible, Terraform) — you treat infrastructure as code. - Performance and reliability mindset — you know how to design for scale and uptime. Bonus Points - Certifications: F5 CTS, Palo Alto PCNSE, Fortinet NSE, Cisco CCNP/CCIE, AWS/Azure/GCP Network Specialty. - Experience with SASE, Zero Trust, or Cloud Security Posture Management frameworks. - Strong background in large-scale network transformations or multi-cloud migrations. What Makes You a Fit - You build secure, scalable, self-healing networks that never go down. - You’re cloud-native to the core — no rack, no cable, no problem. - You can visualize complex architectures and explain them simply. - You stay calm in the fire and find elegant fixes under pressure. - You’re hands-on, proactive, and proud of running a network that just works — flawlessly.
