The Role

To complement our rapid growth, we are sourcing a Network Engineer II to operate in a 24/7 Software-as-a-Service (SaaS) environment, taking ownership of complex LAN infrastructure initiatives and driving operational excellence across Cisco Nexus, Palo Alto, and F5 platforms. You will lead projects, own end-to-end troubleshooting, drive automation strategy, and provide technical leadership during incidents — while mentoring junior engineers and representing the network domain to senior stakeholders.

Troubleshooting & Incident Response

  • Own end-to-end troubleshooting of complex LAN connectivity, firewall policy, and load balancer issues, and drive resolution with customers and internal teams.
  • Conduct in-depth analysis of network incidents, identify root causes, and implement preventive measures to reduce repeat occurrences.
  • Lead and coordinate responses to network and security incidents, ensuring timely resolution and minimizing potential impacts.
  • Participate in on-call rotation following the Sun Model schedule; provide technical leadership during outages and lead post-incident root cause analysis and corrective action planning.
  • Lead the review, analysis, and execution of network change requests within the data-center fabric domain, ensuring adherence to change management and risk-mitigation standards.

Projects & Architecture

  • Lead and drive LAN infrastructure projects involving Cisco Nexus switching, Palo Alto firewalls, F5 load balancers, and NDFC fabric management.
  • Partner with cross-functional stakeholders to design and deliver next-generation data-center fabric architectures, leveraging VXLAN, Cisco Nexus Dashboard, Kubernetes networking (Calico), and AI/ML-enabled networking.
  • Manage and operate data-center fabric services across hybrid and multi-cloud environments — on-premises Cisco Nexus infrastructure, GCP, and AWS.
  • Perform traffic engineering and capacity planning to guide long-term infrastructure investments.
  • Develop and maintain technical roadmaps, architecture standards, and configuration policies for LAN, firewall, and load balancer environments.
  • Manage and maintain existing network infrastructure (Nexus, Palo Alto, F5), ensuring reliability, performance, and equipment lifecycle planning.

Monitoring & Observability

  • Develop and report operational and performance metrics using observability platforms including Prometheus, Grafana, and SolarWinds.
  • Define, measure, and report site reliability using SLI/SLO
  • Maintain operational focus on the data-center fabric while coordinating cross-team efforts with network security and load balancing functions to ensure end-to-end service reliability.
  • Analyze historical network incidents to identify systemic issues and inform preventive engineering.

Automation

  • Drive automation strategy and execution using Ansible, Terraform, Python, and CI/CD pipelines for provisioning, configuration, and monitoring.
  • Implement automated remediation to prevent recurrence of known issues.
  • Demonstrate and scale a culture of automation across engineering and operations teams.
  • Track and manage projects, processes, and technology initiatives across the team, ensuring alignment, visibility, and timely execution.
  • Maintain runbooks, topology diagrams, and SOPs.

Security

  • Manage overall network security including routing policies, Palo Alto firewall rules, and access controls to protect infrastructure.
  • Own all operational aspects of network security infrastructure — OS maintenance, vulnerability management, capacity planning, lifecycle management, and certificate administration.

Requirements

  • Bachelor's degree in computer science or a related technical field preferred, or equivalent practical experience.
  • Minimum 5 years of experience in medium-to-large networks, IP routing, switching, and security principles in a production SaaS or enterprise environment, including experience as a technical subject matter expert.
  • Deep hands-on expertise with Palo Alto firewalls — security policy design, Panorama management, Global Protect VPN, and threat prevention.
  • Advanced experience with F5 BIG-IP — LTM, GTM, iRules, SSL offloading, and application delivery configurations.
  • Expert-level knowledge of Cisco Nexus 9k/7k/5k/2k, NX-OS, and NDFC, including VXLAN/EVPN fabric deployments.
  • Extensive hands-on experience with software-defined networking (SDN) — OpenStack Neutron and Calico (Kubernetes).
  • Hands-on skills with Cisco IOS required; Nexus OS and NDFC expertise required.
  • Proven experience automating infrastructure processes and deployments using Ansible, Terraform, Python, and CI/CD pipelines, with demonstrated ability to drive and scale a culture of automation.
  • Demonstrated expertise in LAN protocols and technologies — VXLAN, EVPN, OSPF, BGP, MPLS, and STP/RSTP — with strong hands-on experience with dynamic routing protocols, particularly BGP in data-center fabric environments.
  • Experience implementing solutions involving large data centers, inter-business routing plans, site-to-site IPSec VPNs, firewalls, and MPLS VPNs.
  • Strong experience with network monitoring and observability tools — SolarWinds, Prometheus, Grafana, NetFlow, SNMP, and packet brokers.
  • Demonstrated experience with incident response, root cause analysis, change management, and operational governance; experience defining, measuring, and reporting reliability using SLI/SLO metrics.
  • Knowledge of Linux network functions and SaaS/cloud-based environments.
  • Knowledge of AWS and GCP cloud platforms, including cloud networking concepts such as VPCs, security groups, transit gateways, and cloud-based load balancing.
  • Proven ability to mentor engineers, lead technical projects independently, and manage multiple initiatives in parallel, with demonstrated project management skills.
  • Excellent communication skills, both oral and written; ability to clearly represent technical domains and team outcomes to senior leadership and non-technical stakeholders.

Nice to Have

  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
