You should be confident taking ownership of technical issues and implementing stable, secure, and scalable solutions.

Required Experience

• Solid hands-on experience with Cisco routers, switches (Catalyst/Nexus), and SD-WAN
• Strong knowledge of routing protocols (OSPF, BGP)
• Experience with Palo Alto firewalls (Panorama / PAN-OS)
• Comfortable with Cisco ISE and 802.1x

• Experience resolving BAU issues and supporting project-based delivery
• Excellent documentation and communication skills
  
  

Desirable experience:

• Familiarity with Python or Ansible for scripting and automation
• Experience with SolarWinds (NPM/APM/NetFlow)
• Awareness of ITIL practices
• Certifications such as CCNA, CCNP, or AZ-700 are advantageous but not essential
  
  

Why Apply:

• Work in a stable, low-incident environment with a clear roadmap for improvement
• Hybrid working (1–2 days on-site) with flexible arrangements
