On Call Network Engineer information

What is an on call network engineer?

On Call Network Engineers are IT professionals responsible for maintaining, troubleshooting, and repairing computer networks outside of regular business hours. They are available on standby to respond to network emergencies, outages, or critical incidents that may occur during nights, weekends, or holidays. Their main goal is to ensure network reliability and minimize downtime by quickly diagnosing and resolving issues. On Call Network Engineers often work remotely or may need to travel to data centers or office sites as needed. This role is essential for organizations that require 24/7 network availability and support.

What are some common challenges faced by on call network engineers and how can they prepare for unexpected issues?

On call network engineers often encounter challenges such as urgent network outages, unpredictable system failures, and after-hours incidents that require quick troubleshooting. To effectively manage these situations, it’s essential to be familiar with the organization's network topology, maintain up-to-date documentation, and utilize monitoring tools to proactively identify issues. Strong communication skills are also important, as engineers may need to coordinate with other IT teams and clearly report on incident status. Preparing by reviewing recent change logs and staying current with system updates can help minimize response times and improve outcomes during emergencies.

What are the key skills and qualifications needed to thrive as an on call network engineer, and why are they important?

To thrive as an On Call Network Engineer, you need a solid understanding of network protocols, troubleshooting expertise, and typically a degree in computer science or a related field, often supported by certifications like Cisco CCNA or CompTIA Network+. Familiarity with network monitoring tools (such as SolarWinds or Wireshark), firewalls, VPNs, and ticketing systems is crucial for efficiently diagnosing and resolving issues. Excellent problem-solving skills, strong communication, and the ability to stay calm under pressure help you quickly address urgent network outages or incidents. These skills ensure minimal downtime, reliable network performance, and effective collaboration during critical situations.

The On Call Network Engineer and Network Support Specialist roles share similar certifications and work environments but differ mainly in their focus. The On Call Network Engineer is typically called upon for urgent, on-demand network issues, often working in emergency situations. In contrast, the Network Support Specialist handles routine troubleshooting and ongoing support tasks.

Job description

What You'll do:

  • Design & Develop: Build and operate the self-hosted GitHub Actions runner fleet on GKE including autoscaling, reliability tuning, and zombie-runner cleanup.
  • GitOps & Delivery: Own the ArgoCD topology powering CI/CD deployments - central architecture, cluster connectivity, ApplicationSets, production reliability (PDBs, replicas, spot-node avoidance), and event-driven flows via Argo Events + GCP PubSub.
  • Shared Platform Components: Maintain and evolve the Helm charts and ApplicationSet patterns used by every Kubernetes workload - versioning, release process, backward compatibility, and developer ergonomics.
  • Jenkins Platform Ownership: Own and evolve our Jenkins environment including shared libraries, controllers and agents, plugins, credentials integration, JVM upgrades and platform reliability. 
  • Self-Service Tooling & Migration: build resusable GitHub actions workflows, actions, and templates, while driving migration from Jenkins and partnering on shared developer tooling 
  • End-to-End Ownership: Lead complex platform projects from architectural design through implementation and long-term maintenance - identifying system-wide bottlenecks before they become outages, and owning the outcomes well past the ship date.
  • Operational Excellence: Own pipeline reliability end-to-end - observability with Datadog (dashboards, monitors, runner log analysis, cluster tracing), incident response and on-call rotation via PagerDuty, plus secrets rotation and vulnerability response.
  • Global Collaboration: Partner with distributed teams of architects, infrastructure and security engineers, and every product team that consumes the platform - coordinating across time zones to translate their pipeline needs into golden paths, reusable workflows, and self-service tooling.

What you'll bring:

  • CI/CD Platforms: Deep expertise in Jenkins administration, Groovy shared-libraries, Docker-based agents, GitHub Actions, reusable workflows, self-hosted runners, secrets management, and pipeline troubleshooting.
  • Cloud & Containers: Strong Kubernetes(GKE) administration, cluster optimization, networking, kubernetes internals, and hands on experience with GCP and AWS services
  • GitOps & Delivery Tooling: Hands-on experience with ArgoCD (ApplicationSets, sync strategies, alerting), Helm chart authoring and versioning, and Argo Events or comparable event-driven delivery patterns.
  • Infrastructure as Code: Strong proficiency with Terraform for GKE clusters, GCP resources, and CI/CD-related modules.
  • Observability: Hands-on experience instrumenting and operating pipelines with Datadog - custom metrics, dashboards, monitors, and distributed tracing.
  • Incident Response: Experience running production on-call with PagerDuty - rotation management, alert routing, escalation policy design, and post-incident review.
  • Artifact & Image Management: Experience with container registries - JFrog Artifactory (including Xray/Curation scanning) and GCP Artifact Registry - and image lifecycle policies.
  • Programming: Comfortable shipping production code in at least one of Go, Python, or Node.js - enough to build controllers, GCP Cloud Functions, glue services, and AI-assisted pipeline tooling.
  • AI Development: Experience or knowledge building or deploying LLM-based applications, AI-assisted developer tooling, or managing AI infrastructure for engineering workflows.
