Incident Response & Post-Incident Engineering: Participate in the on-call rotation for network services. Lead or contribute to post-incident reviews, turning root causes into preventative engineering changes (new alerts, automations, capacity adjustments, or documentation) that reduce MTTR and recurrence.
AI-Enabled Network Operations: Use AI tooling (e.g., LLM-based assistants, AIOps platforms) to accelerate alert triage, anomaly detection, and root cause analysis, while keeping humans in control of decisions. Identify opportunities to embed AI in network operations workflows (e.g., capacity forecasting, configuration drift detection) and help implement these safely and effectively.
Experience and qualifications
Network Engineering & Operations Background: Significant hands-on experience (4-7 years) in network engineering, network operations, or closely related roles in modern, fast-paced environments (e.g., SaaS, enterprise IT, multi-site corporate networks, or cloud-native infrastructure).
Routing, Switching & WAN Expertise: Deep practical experience designing and operating enterprise LAN/WAN environments, including routing protocols (BGP, OSPF), switching (VLANs, STP, MLAG/VPC), and SD-WAN technologies. Experience with multi-site network architectures and global traffic management.
Fortigate Firewall & Network Security: Proven experience configuring and administering Fortigate/FortiOS firewall platforms, including policy management, VPN (IPSec and SSL), SD-WAN, and high-availability configurations. Experience implementing network segmentation and zero-trust network access principles. Familiarity with other firewall platforms (e.g., Palo Alto, cloud-native firewalls) is a plus.
Multi-Cloud Networking: Hands-on experience with cloud networking across GCP, Azure, and AWS, including VPC/VNet design, peering, transit gateways, cloud-native load balancing, and hybrid connectivity (VPN, Direct Connect/Cloud Interconnect/ExpressRoute). Experience managing network infrastructure across multiple cloud providers simultaneously is strongly preferred.
Automation & Infrastructure as Code: Strong experience with network automation tools and frameworks (e.g., Ansible, Terraform, Nornir, NAPALM, or vendor-native APIs) and with scripting/programming languages (e.g., Python, Go, or equivalent) to automate network provisioning and configuration management. Track record of converting manual, repetitive operational work into reliable automation and self-service capabilities.
DNS, DHCP & IPAM: Practical experience operating and automating foundational network services at enterprise scale, with a focus on reliability, auditability, and integration with broader infrastructure automation.
Network Monitoring & Observability: Proven experience with network monitoring and observability platforms (e.g., SNMP-based tools, Datadog, ThousandEyes, LibreNMS, or similar), including building dashboards, tuning alerting, and working with SLIs/SLOs and error budgets for critical network services.
