• Incident Response: Provide senior-level troubleshooting and root cause analysis for critical network issues, driving swift resolution with minimal impact.
• Operational Readiness: Manage and respond to PagerDuty alerts while participating in a global on-call rotation to maintain 24/7 network reliability.
• Collaboration & Reliability: Partner with IT Operations teams to reinforce network performance, availability, and security through proactive monitoring, automation, and architectural improvements.
• Continuous Innovation: Research evolving threat landscapes and evaluate new network security tools, ensuring the enterprise stays ahead of emerging risks.

Basic Qualifications

• Experience: 8+ years of progressive experience in enterprise network engineering, design, and operations within large-scale, globally distributed environments.
• Certifications: Professional-level network certification (e.g., CCNP, JNCIP, or equivalent).
• Core Networking Expertise: Extensive hands-on experience with advanced TCP/IP networking, routing protocols (BGP, OSPF), MPLS, and modern network architectures.
• Network Automation: Demonstrated proficiency in network automation and infrastructure-as-code using tools such as Python, Ansible, Terraform, or similar.
• Operating Systems: Familiarity with cross‑platform corporate environments, including macOS, Windows, and other enterprise operating systems.
• Security Tooling: Proven experience with DNS security platforms and Zero Trust solutions (e.g., Cloudflare, Zscaler, Cisco Umbrella).

Preferred Qualifications

• Cloud Networking: Hands-on experience designing and managing networking in public cloud environments such as AWS, GCP, or Azure.
• Security Expertise: Strong background in enterprise network security, including DDoS mitigation, IDS/IPS, DNS security, and Zero Trust architectures.
• SaaS Security Tooling: Deep understanding of modern networking and SaaS-based security platforms (e.g., Zscaler, Cloudflare, Cisco Umbrella) and enterprise firewalls (e.g., Palo Alto).
