Job Overview

About the Role:

The team:

ou will be joining a high-impact infrastructure team dedicated to building, securing, and automating our global network backbone. We are a group of engineers who believe in "Infrastructure as Code" and are transitioning from traditional network management to a fully automated, self-healing network environment. We prioritize stability, security, and scalability, working closely with DevOps and Cloud teams to ensure seamless application delivery.

Responsibilities and impact:

Core Network Engineering (Juniper, Palo Alto, F5)

• Juniper Routing & Switching: Manage the full lifecycle of Juniper EX/QFX switches and MX routers. Configure and troubleshoot complex routing protocols (BGP, OSPF), VLAN segmentation, and port security.

• Security Operations: Administer Palo Alto firewalls. Manage security policies, analyze traffic logs for "Deny/Drop" issues, and implement User-ID/App-ID features to secure business flows.

• Application Delivery: Manage F5 BIG-IP load balancers, including Virtual IP (VIP) creation, pool management, and SSL offloading.

Infrastructure as Code (IaC) & Automation

• Terragrunt & Terraform: Maintain network infrastructure state using Terragrunt. You will be responsible for keeping configurations "DRY" (Don't Repeat Yourself) and managing infrastructure-as-code pipelines.

• Ansible Automation: Create and maintain Ansible playbooks to automate routine tasks such as OS upgrades (Junos/Pan-OS), bulk config updates, and compliance auditing.

What we’re looking for:

Must-Have Technical Skills

• Juniper Networks: Expert-level knowledge of Junos OS (CLI), routing (BGP/OSPF), and switching.

• Security: Strong hands-on experience with Palo Alto Networks (Panorama experience is a plus).

• Load Balancing: Proficiency with F5 LTM (Local Traffic Manager).

• Automation:

• Terragrunt: Must understand state file management and modular infrastructure code (not just basic Terraform).

• Ansible: Ability to write playbooks from scratch for network automation.

Nice-to-Have Skills

• Alkira: Experience with Cloud Network as a Service (CNaaS).

• Public Cloud: AWS (Advanced Networking) or GCP networking knowledge.

• Scripting: Python for network automation.

Soft Skills & Attributes

• Executive Presence: Ability to communicate complex technical issues clearly and calmly to non-technical leadership.

• Independence: Capable of traveling to client sites and executing deployments solo without constant supervision.

• Proactive Mindset: You don't just close tickets; you identify why the issue happened and fix the root cause.
