About the role

We are seeking an experienced and hands-on Level 3 NOC Engineer to join our Global Network Operations Center. This position plays a vital role in ensuring the performance, availability, and security of our edge compute platforms, SD-WAN environments (Versa), container workloads, and cloud-connected infrastructure. The ideal candidate will have extensive Linux and networking experience, a proactive mindset, and a passion for diving deep into technical issues to resolve incidents, improve systems, and support mission-critical applications in challenging, distributed environments. You'll collaborate with engineering, support, and deployment teams and act as a senior escalation point within a 24/7 global operations model.

Responsibilities

Monitor and troubleshoot distributed edge compute and Versa SD-WAN platforms to ensure high availability and performance.

Respond to escalated incidents from Level 1/2 teams, performing deep-dive diagnostics across Linux, virtualized, containerized, and cloud environments.

Perform advanced troubleshooting of complex production systems-e.g., out-of-memory issues, application crashes, packet loss, or routing anomalies.

Use observability and monitoring tools (e.g., Grafana, SolarWinds, DataMiner) to detect and act on system anomalies; contribute to alert optimization and dashboard tuning.

Support changes and updates to compute nodes, appliances, and edge services under formal change control processes.

Participate in service restoration, incident post-mortems, and root cause analysis.

Collaborate on recurring issue identification and automation opportunities to reduce manual effort.

Create and maintain operational documentation, troubleshooting guides, and SOPs/runbooks.

Participate in a global 24/7 shift-based coverage as needed.

Required Skills & Experience

Extensive and strong hands-on experience with Linux system administration and troubleshooting in production environments is a must (e.g., out-of-memory issues, application crashes, connectivity issues).

Familiarity with Type 1 and Type 2 hypervisors (e.g., KVM, VMware ESXi), including passthrough configuration, resource tuning, and troubleshooting.

Experience with public cloud platforms (e.g., Azure, AWS), including VM provisioning, virtual networking, SSO setup, and datastore configuration.

Solid understanding of IP networking protocols and services: TCP/IP, DNS, DHCP, NAT, VLANs, routing (BGP, OSPF, RIP), VPNs, proxies, and firewalls.

Strong troubleshooting skills using network tools (e.g., ping, traceroute, tcpdump, Wireshark).

Proficiency with virtual NICs, Linux network stacks, and interface configuration.

Hands-on experience testing and troubleshooting REST APIs using Postman, Swagger, CURL, and Python scripts. Familiarity with reading Swagger definitions to automate or validate API workflows.

Exposure to containerized workloads and orchestration, including Docker, Kubernetes, or K3s.

Familiarity with infrastructure automation tools such as Ansible, Terraform, or Bash scripting.

Foundational understanding of TPM, encryption, and measured/secure boot is a plus (can be taught internally).

Experience with tools like ServiceNow, Jira, or other ITSM platforms for case and incident management.

Strong written and verbal English communication skills with the ability to clearly document issues, escalate appropriately, and collaborate across teams.
