The posting

CLIENT SUMMARY

Our client is a global technology services provider specializing in comprehensive, enterprise-grade IT infrastructure management and digital transformation solutions. Delivering robust managed services to a diverse portfolio of international organizations, they focus on driving innovation, operational resilience, and continuous service optimization across hyperconverged infrastructure, multi-cloud, and cross-technology environments.

RESPONSIBILITIES

The Senior / L3 Network Engineer is a subject matter expert responsible for the high-level design, provisioning, and optimization of enterprise network infrastructure across multi-client environments. This role moves away from traditional manual administration, championing a modern, code-centric approach to network operations.

As an L3 engineer, you will serve as the ultimate escalation point for complex network incidents , architect scalable network fabrics, and build continuous integration pipelines to automate network infrastructure deployment.

1. Network Infrastructure & Automation (IaC)

  • Network Architecture: Partner closely with traditional network engineering and software development teams to design highly scalable, resilient, and fault-tolerant network topologies.
  • Infrastructure as Code (IaC): Automate the provisioning, configuration, testing, and lifecycle management of core network hardware and virtual appliances-including routers, switches, firewalls, and load balancers.
  • CI/CD Deployment Pipelines: Develop, maintain, and optimize robust CI/CD pipelines engineered explicitly for deploying network configurations and operational code safely into production.
  • Source of Truth & Version Control: Maintain and govern centralized Git repositories for all automated scripts, configurations, and network code, ensuring a secure audit trail.

2. Advanced L3 Network Operations & Support

  • L3 Escalation Support: Act as the highest tier of internal technical escalation, diagnosing and resolving complex, multi-domain network performance issues and outages.
  • Load Balancing & Traffic Management: Configure, maintain, and troubleshoot enterprise load balancers (such as F5 LTM) to ensure optimized traffic distribution and maximum uptime.
  • Proactive Performance Monitoring: Implement and tune advanced network monitoring and logging platforms to gain deep visibility into network health and preemptive fault discovery.
  • Trend Analysis & Ticket Reduction: Conduct thorough trend analyses on recurring infrastructure alerts to engineer permanent automation fixes, systematically driving down manual ticket volume.

3. Change Governance & Operational Leadership

  • High-Risk Maintenance: Plan, document, and execute critical network maintenance, firmware upgrades, patching windows, and disaster recovery simulation testing.
  • Risk Mitigation: Author comprehensive change management records, identifying structural risks and establishing bulletproof rollback and mitigation strategies.
  • Team Upskilling: Actively mentor and provide technical triage documentation and guidance to L1 and L2 engineers to improve initial line troubleshooting accuracy.

REQUIREMENTS

Technical Certifications (Highly Valued)

  • Core Networking: CCNA is a mandatory technical requirement. CCNP (Enterprise, Routing & Switching) or equivalent professional certification is highly preferred;
  • Firewalls & Security Edge: CCNP Security, PCNSE (Palo Alto), or advanced certifications in Fortinet (FortiGate/FortiManager) or Check Point architectures.

Tooling & Ecosystem Expertise

  • Network Automation & IaC: Ansible (for network configuration management) and Terraform (Infrastructure as Code).
  • Network Source of Truth: Experience with NetBox or equivalent IPAM tools.
  • Version Control & Pipelines: Extensive hands-on usage of Git, GitHub, or GitLab CI/CD systems.
  • Monitoring Platforms: Experience utilizing open-source or enterprise monitoring toolsets like Prometheus and Grafana.
  • Core Network Services: Solid understanding of enterprise core services including F5 LTM/WAF, Cisco ISE AAA services, NTP, and Point-to-Point/Internet routing architectures.

Academic & Baseline Experience

  • Education: Bachelor's degree or equivalent professional qualification in Information Technology, Computer Science, or Network Engineering.
  • Experience: Proven track record operating in an L2/L3 infrastructure capacity, ideally within a Managed Services or large scale enterprise environment.

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

That is how we know which CVs get called.
