Senior Network Systems Engineer

Job Summary

We are looking for a Senior Network SRE & Operations Engineer to join our Cork team. In this hands-on role, you will be the bridge between traditional network operations and modern NetDevOps or NetAIOps. You will not just keep the lights on-you will treat our global network as code, using your expertise in networking and automation to eliminate manual toil, drive reliability, and ensure maximum service uptime across our hybrid environment.

• Travel Requirement: This role requires 10% to 20% travel to support our global sites, data centers, and collaborate with international teams.

What You Will Do:

• Network Automation & SRE: Design and implement automation workflows (Infrastructure as Code) to replace manual configuration, patching, and troubleshooting.
• Security & Edge Health: Manage and tune the operational health of our security posture, acting as the SME for Cisco ISE (NAC), Palo Alto firewalls, and Zscaler (ZIA/ZPA).
• Enterprise LAN & Data Center: Own the lifecycle and performance of our global wired network and hybrid data centers, heavily utilizing Cisco Catalyst (9000s) and Nexus environments.
• Proactive Observability: Leverage telemetry and APIs via tools like LogicMonitor, SolarWinds NCM, and ThousandEyes to detect and auto-remediate network anomalies before they impact users.
• Escalation & Mentorship: Serve as the final technical escalation point for complex global incidents and champion an SRE culture (SLAs, SLOs, blameless post-mortems) within the networking team.

Job Requirements

• What You Bring:

  • Network Automation: Proficiency in scripting (Python, Go) and automation frameworks (Ansible, Terraform, Nornir).
  • Version Control & CI/CD: Experience managing network configurations using Git, GitLab CI, or GitHub Actions.
  • Core Routing & Switching: Deep, enterprise-scale experience managing Cisco Catalyst/Nexus environments and hybrid cloud connectivity (AWS, Azure, or OCI).
  • Security Operations: Strong operational expertise in administering Palo Alto firewalls and Cisco ISE.
  • Mindset: A strong drive for operational excellence, rigorous change management, and a passion for automating repetitive tasks.

  Highly Desirable Industry Certifications:

  • Automation & SRE: Cisco Certified DevNet Professional or HashiCorp Certified: Terraform Associate.
  • Core Infrastructure: Cisco CCNP Enterprise or CCNP Data Center
  • Demonstrated experience with network automation and IaC is valued more highly than traditional expert-level certifications (e.g., CCIE).
  • Security & Edge: Palo Alto Networks Certified Network Security Engineer (PCNSE) or relevant Zscaler administration certifications (ZIA/ZPA).

  Bonus Points For:

  • • • Experience with Cisco ACI, NAC, or SDWAN (vManage).
      • Operational management of F5 or VMware AVI load balancers.
      • Experience in Manufacturing network environments.
